Title: Fordson tugger hoist
Post by: Chuck Doan on January 10, 2017, 11:04:51 PM
I have begun another unfinished project, a 1/16th scale M.A.C. Skagit tugger hoist. I have been drawing up the parts in Solidworks for eventual 3D printing.  For reference I used the pictures I took of the one at Willits Ca, a few found pictures online, and a sparsely detailed, but scale drawing in the Timberbeast magazine.  The tractor will be another converted die-cast. I have designed the hoist and tractor to be built separately and then joined together on the sled.
Time will tell if it gets built, but it has been fun so far.

These parts will be lost wax cast in brass, so they can support the heavy die-cast tractor. 00-90 screws will join them together.

Very, very ... very inspiring work!




Title: Re: Fordson tugger hoist
Post by: Chuck Doan on January 11, 2017, 09:16:30 AM
Thanks guys! Peter, there will be some wood carving to do! Helmut, I am planning to use the Kyosho roller chain, and the gear teeth mesh, so technically it all could rotate. But it will be a static model, though I will probably test the rotation anyway while making motor sounds (when no one is looking). Theoretically, the opportunity for weathering is very great, which is what I like the most.

You are right Dave, it has a lot in a small package.

Thanks Jerry, I am sure a gas pump will appear somewhere.

Beautiful renderings Chuck!!
I am curious, how do the rear axles of the tractor engage the tugger sprockets? 
Are they keyed, splined, or some other way?

Great project, looking forward to seeing it happen
Rick


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on January 11, 2017, 08:41:17 PM
Thanks Rick! The Skagit sprockets are designed to re-use the splined bushing that normally mounts the rear wheels.

Phew, what a bright look-out! Don't forget rolling the front wheels through some modeling clay and inserting some grass stalks to the gears and chains while making the engine noises ...
Aside of that premature praise I've got to say I'm simply glad you didn't stop posting at all ...

Sorry to nit pick on such a beautiful set of renderings, but you left the throttle (?) rod in the second picture out.  And, in same picture note that the tractor on the skidder in the background still has at least one headlight.

Post by: Chuck Doan on January 16, 2017, 04:20:52 PM
The rear drum did the hoisting, and the forward drum was the haulback line for pulling the main line back out to the load point. I'm sure there were other uses as well for different rigging setups.

I pretty much finished it up, and should be ready to build:

Danbury Mint. Yep, another diecast conversion.


Title: Re: Fordson tugger hoist
Post by: Ray Dunakin on January 17, 2017, 12:28:23 AM
How long did it take you to draw that? Did you use Sketchup or some other CAD program?



Title: Re: Fordson tugger hoist
Post by: finescalerr on January 17, 2017, 02:10:18 AM
SketchUp probably couldn't produce as clean an image of such a complex subject. You use SolidWorks daily, right? Given your expertise, I'm curious how long it took you to crank out that drawing. -- Russ


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on January 17, 2017, 09:25:55 AM
Yes, Solidworks. It's hard to say about the time. A lot of it was spent looking for and at pictures for research. That part is the same regardless of the build method. If I knew the size of the parts and what they looked like at the start, it would probably take me two work days or less to model the items (less the Fordson that was done a couple of years ago.)  There aren't any really hard shapes to figure out on this one.

One cool thing was the chain. SW has a fairly new chain pattern feature that lets you make a rotatable model really fast. I modeled the inner and outer chain links. Then I drew a sketch of the chain path and mated the two links to it, then it automatically fills the path with all the links.

To figure the chain, I used a motorcycle sprocket calculator I found online. I knew the pitch (distance between the chain pins) and I knew the number of sprocket teeth from a Skagit factory spec someone found for me on the Yahoo logging group.  The calculator showed me the pitch diameter for each sprocket and the centers between sprockets for an even number of links. Easy!

Post by: 5thwheel on January 17, 2017, 12:22:08 PM
Beautiful rendering, can't wait to see it in model form.  One suggestion, there should be a slight slack in the chains.


Title: Re: Fordson tugger hoist
Post by: finescalerr on January 17, 2017, 02:03:25 PM
Only two days of actual drawing? At my current level of incompetence that would take me two months!!

Incidentally, I've drawn chain in both AutoCAD and SketchUp ... link by link. Not fun at all.

Post by: Chuck Doan on January 21, 2017, 04:52:07 PM
John Geigle of J and S Technologies invited me to send a file of one of my parts to try on one of his printers. My first impression after receiving it was that it was injection molded. I gave it a quick coat of primer to see how it looked. I used Mr. Surfacer 1500 black, which I have found to be the least forgiving and most revealing primer for finding print lines. This part has the least amount of visible print lines I have ever seen on a part. On most surfaces, there are no visible lines at all, even on the curved sections, which is usually where the lines are most prominent. The lettering came out perfect, it is .06” tall .008 wide and .010 high. The material is grey in color and seems stronger than Shapeways FUD/FXD parts, though I am not inclined to test it. Best of all, there is no wax residue to remove. I can’t gauge the cost difference yet; I have more parts in for quote so I will soon find out, but the time saving in cleanup will be a factor.

After seven years of working with 3D printed parts, I am finally seeing some of the better quality prints becoming available to modelers. And just in time for my new project!

Grey primer after clean-up. I spent less than 10 minutes on it as opposed to 2-3 hours (or more) on a Shapeways parts.

Good thing I read the whole thread before asking how you modeled the chain. I had to do one a few years ago, and it was a nightmare. Is the chain feature new for SW 2017, or was it in 2016?


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on January 21, 2017, 11:16:08 PM
I think it first came out in version 2015. We have 2016, and it worked like a peach. I just recently added some sag (thanks Bill!) just by changing the path sketch.

That is impressive resolution! It would be interesting to stress test a scrap piece of the material to compare it to Shapeways resins.


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on January 22, 2017, 11:20:53 AM


http://www.jandstechnologies.com/

When I received the part, I asked if could post it with their info. John said fine, they are looking for customers!

I haven't broken the part yet, so I don't really know it's properties. I don't think it's any worse than the FUD. I haven't tried any solvents either. Not having any wax to deal with is really nice. The Shapeways FUD/FXD is basically the same tech and material as the parts I first got from Print A Part back in 2009. And they were around before that. Most industry based companies using newer tech don't want to bother with model builders.

I haven't received my quotes yet for the parts I need, so it could still be a surprise for the wallet. So it is promising, but...

BTW, Form 2 printers don't seem to be that expensive...

I received the brass parts for the front section of the hoist. They needed to be strong to support the die-cast tractor. I will probably pin and solder them together. Printed in wax, and then lost wax cast by Shapeways.

The brass parts look really good!
In fact, much smoother than the brass part I got from Shapeways some years back.

Do you have a closeup image of your parts, It would be very interesting to see if the quality of Shapeways brass parts have improved.

Here is a link to my brass part (http://www.folk-rovere.org/mj/bilder/SW_brass_cp_01) for comparasion. The whole assembly of all the coupler pockets  is about 10mmX20mm)

Looking delicious.
Are these from J&S Technologies as well? Did you ask if they are open for general business?

As far as I can see they use a Objet printer, so If they are not taking business from everybody, moddler.com should be able to offer the same quality. They are using Objet printers as well.

Yes, J and S are open to anyone. I think he said it was a Form 2 printer.

The large gear you showed earlier looked far better than the Form 1 prints I have seen. If it really is prints from a Form 2, some dramatic improvements have been made.

And it is a printer that my local model railroad club could afford!

I received the bulk of my parts from J&S. There are some nubs left from the print supports to sand off, but for the most part, the quality is very good. On one drum I left the nut/bolts on (they are .06 wide BTW) and they printed very cleanly. I have never done that before, and it will be a big time saver. The material is fragile, about like the frosted parts from Shapeways. But like those parts, the breaks are clean, and ACC makes a strong repair.

For the record, the gears all mesh perfectly, and they turn with or without engine sounds.

(If you can avoid drooling or spraying you definitely should make engine sounds. They will add so much to the model's realism ....)

Less seriously: Overall, do you prefer the output from Shapeways or the other place -- or do you have a preference? How would you compare strengths and weaknesses?

Great stuff this - have you any info' on the colour of the paint work - would the tractor/engine be the same as the winch assembly or was the winch supplied separate  and bolted to a tractor and come as a different colour ?

Nearly solved the problem - should have looked at the beginning !!
Just looked at the advertisement for the MAC hoist /winch (on page one of your post) and it looks like they used a Ford power uint/tractor  - but I wonder if they supplied the hoist unit separate to bolt to your own tractor unit

Barney, I don't have a clear idea on the color. Logging guys only remember the post-war grey. I am probably going to go with black. They made this unit with mountings for different tractors. I have also seen a John Deere and a Hart-Parr tractor connected to one of these. Supposedly there were others too. I know there is more info out there, but the demise of all but one logging magazine has limited our access. 

Russ, I'm not drooling yet, at least as far as I can remember. The two materials have different issues. The FXD has the wax that needs to be thoroughly cleaned, and somewhat more prominent layer lines depending on the print orientation. The new parts are printed on supports that need to be trimmed. These can imperil finer details and edges and must be trimmed with care. Both materials are brittle, but can be easily repaired if broken. I am leaning towards the newer stuff, but I still don't know the true cost difference yet. I am looking at another local source; I'll report on results when known.

The sled will be a challenge due to the size. I can't fake anything in this scale.

Here is the brass load bearing front with the rest of the frame. I thought of building this a couple of years ago, but I couldn’t figure out how to duplicate the delicate Skagit design in material strong enough to hold up the die-cast tractor. Thanks to a previous unfinished project, I learned about the brass “printing” available at Shapeways.The brass part will be screwed down to the sled, isolating the plastic parts from load. When finished, the difference in materials won’t be detectable.

The chain is from Kyosho, and it's made for big scale RC motorcycles. Thankfully it comes assembled, but it is pretty easy to press the pins out and shorten it up, or to join for longer lengths. The number is GP 15. Kinda pricy, but very accurate for my scale and I don't need a lot. Shop around, the prices vary a lot.

The texture is JB Weld sponged on, and then lightly sanded when dry. I also used JB Kwik for touch ups.

Post by: Chuck Doan on April 16, 2017, 07:25:44 PM
Thanks Guys! Narayan, I used the regular JB Weld, and some JB Kwik for small areas and touch up.

Main difference is the dry time, overnight for the regular and 4-5 minutes for the Kwik (making it best for smaller areas). The regular can be worked for 1-2 hours before it starts to become un-workable.

Finally got a start on the paint and the beginning of the weathering. I have found that a good paint stripping method is as important as any application method. This is the sixth try. I have a vat of Windex, and I’m not afraid to use it!

Some more weekend progress. Added some nuts and the adjusting struts, and continued with the weathering. For what it’s worth, here are the steps. So far this is just a big experiment.

Base coat was Mr. Surfacer Mahogany primer. Followed by hairspray (from a spritzer bottle) airbrushed on. Then a spray can coat of Tamiya enamel Dull Red as a thickener coat for more defined chip edges (multiple or heavy coats of acrylics only tends to make rubbery peels). Then the color coat mix of of Tamiya XF-1 Flat black and XF-63 German Grey airbrushed on. Chipped with a sharp plastic stick after dampening the surface.

Started weathering using Prismacolor Premier pencils. Dip tip in water and rub on sandpaper to get “paint” (can mix colors, no problem) Apply with damp cosmetic sponge: Dab in “paint”, then tamp on a hard surface to unload as desired, and then lightly duft on the model.  Build up or remove, to desired effect. Can be removed with a damp sponge if it goes to heck. Seal with lite Dullcoat spray, which does not affect the penciling. Final step is sodabrushing using a Mini sandblaster and baking soda at 15-20 PSI to dull.

Oil residue is Black and Brown oil paints mixed with very fine powdered dirt.  Applied with a soft brush and edges blended with the sponge. Assuming final coloring/dulling/ glossing will be done when the oil paints finally dry (someday).

Apart from the fact that you use Prismacolor pencils to get paint (never heard of that) I especially like your oil residues.

Chuck-

Amazing. For the JB Weld texturing (which looks spot on) are you just working it with a brush? Ive seen similar texturing done in 1/35 for castings for armor with Mr. Surfacer but never with epoxy. Very interesting. Also JB Weld seems to remain a bit gummy, has that been an issue at all?


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on June 14, 2017, 12:29:25 PM
I use a cosmetic sponge to dab it on. It does remain soft for a long while and will "self heal" until it reaches a certain surface cure time (3 plus hours). So I come back and re dab for a while to re-texture. It dries plenty hard (overnite), but can be sanded. I give it a light sanding to knock down the texture a bit.  The JB Quick is too quick for large surfaces and I wish there was an in between version that surface cured faster.

Builders plate fresh from the printer. 16 micron print layers. .375 x .75” (9.5 x 19mm) Letters are .028 high.  True size would be 6” x 12”   This is the same as Shapeways FXD, but this was not printed by them.

I did a smaller version, maybe .019 high. The letters were legible, but they were more blobby. The text tool in Solidworks doesn't allow kerning, so I can't adjust the space between letters. If I could it might be doable.

Chuck, that is just perfect. Did you have to smoothen the gear's teeth surface to achieve that extremely convincing look of greased sheer metal?
Thank you for posting that. I once knew a guy who made printed magazines. This for sure would have been a more than worthy topic to publish.

Post by: Chuck Doan on August 09, 2017, 01:08:05 PM
Thanks very much!

Volker, the teeth were sanded smooth, and then I used a pencil to apply the metal shine. This was covered with a light coat of Polly Scale high gloss. When the teeth catch the sun, they are quite shiny. I applied the oil paint and dirt mix to the valleys and tops of the teeth, and then the gloss when it dried. The large gear on the rear drum should be neat when done, though I am not excited about the 72 teeth on it!

Thanks Franck!

Finished the builder’s plate and mounted it. McLeod model RR nuts finished it off. These were made of cast steel, but I don't know if the letters were polished or not. So, I just painted it.

Thanks for the nice words!

I made some more progress this weekend. Dry fitting the haulback (trip) drum (pardon the drill bit). The 3/8” diameter (.024 actual) wire rope is 7 x 19 strand stainless from Mcmaster-Carr (the more strands, the more flexible it is). I wrapped 25 tedious feet around the core using super glue to hold it (excess easily removed with acetone). Hardest part was keeping it from kinking and away from the cat. The core is separate from the ends to facilitate handling and do-overs (already needed). I used a heavy wash of black oil paint to simulate well kept and oiled rope. Will make a nice contrast to the war weary look of everything else. The end fitting (closed spelter) was also 3D printed and buffed with Rub N Buff and oil warshed.

Much more to do, thankfully. I haven’t enjoyed a model like this for a long time.

I would go further: Chuck Doan IS the best in his field - far ahead from all of us (and I hope I will not offend anybody here  ::)). Ok, there are a some others too, but all in other branches, and they can be counted on one hand, e.g.
Chris Flodberg, Kim hyun-soo - maritime modelling
Randy Hage, Ichiyoh Haga - diorama modelling
...

But what distinguishes the work of Chuck is, that he has, against current trends, never strived his own style. Maybe you know the work of Adam Wilder and his methode of color modulating or the style of Mig Jimenez - all outstanding modelers without daubts and all with their personal syle.
IMHO Chuck goes a step further: He never cares about styles, he "simply" captures the real thing, and that in such a way, non of all other artists can archieve. His models ARE the real thing.

So... thank you, Chuck, for sharing us your techniques.

Thanks very much again for the nice words! I keep seeing some astounding model work on the internet, and thankfully weathering has become a big thing. Very nice to see (and learn) all the different techniques being used. I consider the hairspray paint chipping method as one of the best ever.

I have now glued the haulback drum in place and installed the bearing caps and 00-90 brass nuts. The grease on the gears was based pics of Shay locos and other open gears. The gear teeth were treated the same as earlier described. I am adding bits of pine needles and such to some of the bearing cap grease; this is another thing seen on some Shays that run in the forest. The chain drive sprockets will eventually attach to the brass axle stubs.  Now I need to figure out how to install the brake strap that winds around the wide end of the drum.

Thanks!

Finally some bench time; I finished the trip drum brake band and spring hanger, and added a grease cup to the bearing.

The brake pad was made from .02 black styrene that was textured on the sides by rolling a file along the edge. Then it was heat formed in a circle shape by taping it to a socket and dipping it in hot water. Then painted with an asbestos-ey white color and glued on. The brake band is .01 styrene strip that was embossed with rivets. I printed the pattern on paper and taped it to the styrene, and then I pressed the rivets to depth using a shaped brass wire in my (non-spinning) drill press, using the depth stop to get consistent sizes. I 3D printed some linkage parts to the brake pedal rod, and installed it all with 1mm brass screws at each end of the brake band.

The spring hanger (that relives pressure when the brake pedal is released) was made from .03 x .09 brass strip that was bent to shape. The spring was made from annealed brass wire and held down with 1mm brass nuts and styrene washers.

The grease cup was printed, sanded and installed with yet another 1mm screw and nut in the base. Painted with oils and fine dirt.

I added the drive sprockets and finally hid that ugly brass axle. I wrapped a section of the roller chain as a mask and then applied the oil paint. The polished areas are made using a pencil, and the oil paint and fine dirt grease mix is finished off (when dry) with touches of clear high gloss.

  The problem with that suggestion is that he uses a kit to demonstrate his painting and weathering techniques . These techniques are possibly achievable for us lesser mortals if we practice enough , but what chance would we have of trying to reproduce in any meaningful form what Chuck does ?

   What it needs is a high quality magazine that is not afraid to publish articles on top quality modelling . There used to be one , but the owner grew old and quit to enjoy pleasures of the flesh in his dotage ,

Finally a reason to exclaim this to the world: Nick, go stand in the corner!

I hope you guys realize that I didn't get "too old" to keep publishing. It just wasn't worth the enormous time and effort to please a handful of superior artists with superior intellects for an insufficient income. As much as I love publicizing a gorgeous model, editing articles and restoring photos, laying out pages and, worst of all, needing advertisers, became too great a burden for too little compensation. The best I can offer is this website and I've always hoped it would be, if not quite enough, then at least adequate.

Sorry, not a thong girl, but today I took a couple of quick shots with the Fordson tractor in place. The tractor will eventually (hopefully) be completely re-done, including the replacement of the current anti-gravity front mount with something more conventional. The main drum is still in process.

A friend told me about Chuck's article. Bob discontinued my Gazette subscription after somebody incorrectly reported a comment I made on this forum, maybe in the "private" Blue Note Room, about his magazine.

I had written, as an honest analysis, that changes in the hobby and, to some extent, Bob's complacence had left the Gazette a caricature of what it used to be. The tattletale told Bob I called his magazine a "comic book". Bob never read the post and never phoned me. Instead he asked Mal Ferrell to call me and, despite my clarification, I never received another Gazette.

Cliques, politics, and childish behavior are symptoms of a dying industry and are the reasons I stopped attending the NG Convention years before I stopped publishing.

Can someone tell those of us who don't get the Gazette what the article is about? Is it this Fordson tugger hoist, or some other project?
Whatever it is, Congratulations, Chuck!

The article is about using 3D printing to produce brass detail parts, such as Chuck has done on his tugger hoist.

Post by: Chuck Doan on March 18, 2018, 04:32:11 PM
Thanks very much! I think it’s been over 14 years since my last gazette article. Just a brief description of “3D printing” brass parts. I thought it would be interesting to folks who haven’t heard of it.

Also got some bench time, finally starting on the main drum. 25’ of stainless line is kinda heavy all wrapped up in one place! And then there are the 144 gear tooth faces to polish. :-\

That photo gives a pretty good idea of the size of your model and its parts. There's no room to approximate anything; every detail is in your face. On one hand I understand why you moved up from 1:48 but, on the other, the model is BIG and every nuance is important. No wonder it's heavy. Satisfactory. -- Russ

Go big or go home!
Big stuff equates to lots of small models assembled into the final piece.
That is why those of us who love to scratch build end up in larger scales.

Marty and Jerry, go stand in the corner. In Marty's case, that may be the only way to keep him around the forum for a while.

As a trivial matter of interest, the first time I met those two rascals in person was at a National Narrow Gauge Convention and, as I recall, they were sitting together at a table and drinking adult beverages. It was a shock from which I never have recovered.

Nick, although I have hung out with Mario a couple of times, several years after meeting Marty and Jerry, those experiences were nothing in comparison to the trauma I suffered a few years ago when you phoned me. I'm still on heavy medication and full recovery is doubtful.

Erratic behavio(u)r is a trait I have enjoyed and cultivated since birth, possibly because my therapists kept me in a humidor for 11 years.

Hi Russ ,

   I attend your sermons every day , but I sit at the back so as not to draw attention to myself . I always whisper a Hallelujah when you say something profound .

 Your trauma was nothing to the shock my bank account had at the cost of the phone call to you .

  I had a new knee just before Christmas ( must be all the praying I do ) so have supposedly been taking it easy for the last three months . So I have just been building/fitting the kitchen in the house that has been on the go for the last ten years .

   Modelling wise , not a lot . I thought I would get some done during my enforced layup , but that didn't happen . I have started a couple of projects , but they await completion when I find some motivation again .

 

 Chuck ,

  Sorry to hijack you thread . Yet again .

  I haven't commented on your latest build , because , as usual , the quality of your modelling has rendered me speechless . Again .

   Will this model be on a diorama or just a stand alone model ?

  Nick

Post by: Chuck Doan on April 14, 2018, 08:41:45 PM
Hi Barney,

It is Stainless 7 x 19 miniature braided wire from Mcmaster-Carr. If you search the Mcmaster site for Part no. 3461T632, this will get you to the catalog page with details. Somewhat pricey, but very flexible; almost like a wet noodle. It was perfect for me and they made the two exact sizes I needed. Apparently, the higher the number, the more flexible it is.

Nick, you're always welcome, glad to hear you are still kicking. No diorama for this (assuming I finish it). That would be a crazy amount of ground cover to do!

Thanks very much! Yes, that sun is both 16 times brighter, and hotter! Or at least it felt that way today.

Thanks Dave, nice to hear from you again; hope you’re latest project is going well. The drums were made in 3 pieces; the core and the two ends. Each item was pre-painted and weathered. After primering, the ends were put in my drill press “lathe” and I used dampened Prismacolor Premier pencils to apply the rust rings. This was followed by a damp toothpicking in an annular fashion to blend them. Then Dullcote followed by a soda blasting to dull the traditional not-so-Dull Cote. The gypsy drum was finished in a similar way, but I used a regular lead pencil to get the steel look started, and then some Prisamcolor pencils applied in an annular way to simulate cable winding marks. No Dullcote for this.

Today, I got the main brake strap applied, along with it’s linkage to the brake pedal shaft. All of these parts are made from styrene, brass wire and brass nuts from Walthers. The nuts  tension the brake strap over the drum. The spring was wound from brass wire.

Thanks very much for the nice words! This has been a lot of fun so far.

I have installed the rear drum brake spring thingy, and the gear “guard”. The spring bracket was bent up from .032 x .125 K and S brass stock, and the guard was made from .01 x .188 Evergreen styrene. I cut the strip to length and heat formed it in boiling water while it was taped over an empty soda can, which just happened to be the right diameter. I bashed it up a bit; prototype photos show them bent up pretty well, not sure if by logs or brawling loggers.

This side is done, now to finish the operator controls on the other side.

Started on the chain guard. Made from .010 sheet styrene with brass strip bent up for the support brackets. Using 1mm and 00-90 nuts and screws to fasten.

(https://media.fotki.com/2v2JV8juLxU6NJ5.jpg)

Primed with Mr. Surfacer Mahogany spray, then hairspray airbrushed on, then Tamiya XF flat yellow with a few drops of flat red. Chipped with a toothpick and a soft nylon brush.

I found a crudely painted number in a picture I had, and reduced it and printed it on paper. Then taped it over some Tamiya masking tape that was stuck to a piece of glass. Cut out the number with an X-acto knife and then pulled up and re-applied the tape “mask” to the guard and airbrushed it black. Chased it with some handbrushed paint for a painted-on look. (Ray Dunakin is a lot better at this than I am.)

(https://media.fotki.com/2v2JV8jUhxU6NJ5.jpg)

The inside wasn’t painted yellow, and I sponged on some Prismacolor pencil “paint”, then speckled it with thinned oil paint (flick a light brushfull over a toothpick). Followed up with oil paint mixed with dirt, and pigments.

The guard is about as fragile as a potato chip, hoping I get it done and installed safely.

"[T]echnically it all could rotate. But it will be a static model, though I will probably test the rotation anyway while making motor sounds (when no one is looking).

Chuck, once again, an absolutely incredible job!

But, after all the anguish you have caused us on this project, leaving a number of people speechless, others staring endlessly at the photos, and all of us needing therapy of some sort to address our feelings of inadequacy, I'm thinking a video of you testing the rotation would be in order and go a long way towards restoring our sanity.

Well Chuck, you've certainly reached the pinnacle of realism. No matter how long or how closely one studies this model, there is literally nothing to break the illusion of reality. What's more, the studying is a pleasure! The construction, paint, and weathering all combine to perfectly portray the singular beauty inherent in a well-used piece of industrial equipment.

Chuck-- I'm with Ray about reaching the pinnacle of realism... though maybe we should say "nearing" so there can be the possibility of an encore. This is WAY more than a model, and there is a great deal of satisfaction in just seeing such outstanding work. Your hand was a great background, as it implies so much more than simply being a scale reference. (I have always wanted to make a really large quarter to place in model photos.)

Chuck,

I'm still in awe of your incredible modeling skills and even more: your eye for detail, wear and traces/stains of time and use. I didn't dare to ask: May this work of art have a glimmer of politicallyness? The yellow cover once more vaguely reminds me of a statesman's headdress or something. Howsoever: Great work.

Here are all the individual 3d printed parts used in the hoist. The bulk of the parts were made from plastic. The orange items were cast in brass from 3d printed masters for strength. All were modeled by me in Solidworks, based on my research of the prototype.

Some sub assemblies could have been consolidated, but I made individual parts to facilitate sanding the print lines, and also for painting and assembly.

The only sub-assembly painted as an assembled unit was the frame (only 6 redos). All other parts were painted separately and then assembled. I knew I would screw up some of the painting, and this way I only had to strip and redo a single item instead of an entire assembly. This decision paid off! Over and over.

Thanks again for the nice words! Thanks Russ, adequate is just enough without being too much. The best thing is trying new techniques. This is the biggest 3D printed model I have attempted, and I enjoyed modeling it twice, once on the computer and then in Real D. Using oil paints for the first time as well as discovering the unexpected Prismacolor “paint” added to the fun.
 
It has been over ten years(!) since my last Fordson, so I am also trying new things on this next one. Instead of re-working some of the marginal Danbury parts, I am going to try printing them. They will definitely have better detail than I achieved last time. So far, I am just going to do the parts above the engine and still use the die-cast body parts. Those parts are more difficult to 3D model, but I might look into having them scanned after I get the assembly re-done.

Here are the beginning computer models:

Awesome!

I just got back from my annual Nevada trip last week. While I was there, I came across the remains of a Fordson in the ruins of a mine structure. It looked like it had been used to power a compressor. I wish I could have gotten photos of it but it was late at night, and there was too much debris to get close.



Title: Re: Fordson tugger hoist
Post by: finescalerr on August 30, 2018, 12:17:20 PM
Chuck, how did you arrive at the dimensions for those parts? Presumably they must fit the Danbury tractor. Did you spend a lot of time with a ruler and a real Fordson or did you "imagineer" the dimensions from photos and common sense? Either way I expect the results to be most satisfactory. -- Russ

Lacking access to a tractor or blueprints, I am going with Pretty Damn Close (PDC). I am using the Danbury parts for the basic sizes, as well as pictures of individual parts from auction sites and restoration forums for the finer details.

To keep my hand in real modeling, I made a quick 5 lb. grease can from a Grandt Line O scale part. Wrapped it with a Microscale gas station decal and grunged it up with oil paints. There could be 6 months worth of clutter alone on this.

Title: Re: Fordson tugger hoist
Post by: finescalerr on October 10, 2018, 12:52:32 AM
That was going to be my first question. The second is how did you break down the printed parts. I see as many as nine on the cast metal depending on whether the radiator frame is a single piece or consists of two sides.

My third question is what you think about the 3-D parts from your new supplier. I see some "grain" you may have to fuss with to remove, especially around the Fordson lettering.

Russ


Title: Re: Fordson tugger hoist

Title: Re: Fordson tugger hoist
Post by: Chuck Doan on October 10, 2018, 09:01:26 PM
I am still shopping around for printer services. 3D Hubs is an interesting place. These parts are combatable to Shapeways; some grain, but nothing too bad. I can't remember what the printer name is. Printed on wax rather than supports. I want to try other printers, but it is an expensive thing to just try.

Good eye Russ, yes 9 parts. The radiator is just like the prototype, 4 parts. I figured they would be easier to sand (and paint) as separate parts, and now I can install my new core from the top instead of the back as I had to do on the Danbury one. I made tabs and it all fit together perfectly. I am currently soaking them in Bestine solvent which dissolves all the wax, inside and out.


Title: Re: Fordson tugger hoist
Post by: finescalerr on October 11, 2018, 01:11:13 PM
Shapeways and other commercial printers are fine for most stuff. When the quality must be as good as possible, we may have to look for a small "mom and pop" outfit. Geoff Ringlé, who used to post here, uses a jeweler on the east coast. Volker uses a guy in Germany. In both cases the results are clearly superior. The key is that those shops spend much more time on the print itself and have an intimate knowledge of resins and their printer's strengths. Chuck, if you want a referral, send me an e-mail. -- Russ

I couldn’t bring myself to modify the Danbury manifold, so I spent some time making my own. This is a different version than the Danbury one, and I did a little photo scaling to figure most of it out. The nuts and pipes will not be printed, but will be added as separate items.

Title: Re: Fordson tugger hoist
Post by: finescalerr on November 04, 2018, 03:09:49 PM
That might depend on who does it. If Shapeways, while the price might be lower, you might have to clean it up a lot. If a 3-D printing expert were able to produce parts requiring virtually no cleanup, it would require a lot more time and care to print and the price might be much higher.

By the way, remember how you were a little reluctant to learn SketchUp at first? I wish more people were as willing to overcome inertia.

Russ

I finished the manifold and cylinder head.

(https://images51.fotki.com/v731/photos/9/777399/15566928/xc-vi.jpg)


The previous parts were about sixty dollars, and this cluster is about forty (printed in the higher res version material). I did double up on the parts to allow for different orientations. In 1/16th scale, if everything was done including the wheels, probably over 250. Maybe more.

Title: Re: Fordson tugger hoist
Post by: finescalerr on November 05, 2018, 11:01:44 PM
Chuck uses a very expensive professional program called Solid Works, something he works with in his profession everyday. The rest of us use SketchUp and it is pretty much all we need. Most hobbyists use the free version (SketchUp "Make"). It is available from a company called Trimble at https://www.sketchup.com (https://www.sketchup.com). Any problem you encounter is more likely to be with a printing company than with SketchUp.

I'd encourage you and anyone else on this forum to download the program and mess around with it. You should be able to learn the basics quickly (two or three sessions) and it's fun. Our forum has a long sticky describing its use: http://www.finescalerr.com/smf/index.php?topic=877.0 (http://www.finescalerr.com/smf/index.php?topic=877.0). Marc Reusser spent a lot of time creating the original instructions and others added a lot of very useful information for when you're a little farther along.

Creating a 3-D drawing is almost like scratchbuilding a model except you do it with a keyboard, mouse/trackpad, and monitor instead of knives, saws, and files. It can be very satisfying.

Russ


Title: Re: Fordson tugger hoist
Post by: Hauk on November 06, 2018, 05:16:04 AM
I have used Sketchup quite a lot, both at work and as a hobbyist.

But for creating .stl masters for 3D-printing, I have switched to Autodesk Fusion360.

This is a program with features comparable to SolidWorks. But it is free for hobbyists and small businesses. You can earn up to $ 100.000 a year without paying for the software.

The learning curve is a bit steeper than SketchUp, but there are tons of tutorials and videos available online.

I really urge people to look into Fusion360 if they are serious about making masters for 3D printing.


Title: Re: Fordson tugger hoist
Post by: finescalerr on November 06, 2018, 02:50:48 PM
I can't find a free version, only a free 30 day trial version with "conditions". I never trust conditional offers, and we can't read the conditions beforehand, so I didn't download the software. Maybe you could help us with that. My experience with AutoDesk products has been positive; Fusion 360 may well be excellent. -- Russ


Title: Re: Fordson tugger hoist
Post by: Greg Hile on November 07, 2018, 01:11:52 AM
I have both SketchUp (I sprung for the Pro version this year) and Fusion 360. There are two free versions of SU, a web version called SketchUp Free, and the old SketchUp Make 2017, a downloadable program that isn't being upgraded but is still quite usable and, to many users, preferable over the web version. To get the Make version, go to https://www.sketchup.com/products/sketchup-make (https://www.sketchup.com/products/sketchup-make). There are some features of the pro version that do not come with Make but overall they are very powerful programs.

Fusion 360 works the same way SU used to. You download a trial version and after the 30-day trial is over you can convert to the free account that Hauk referred to. I have had the account for a year or two and have never had any problems. Like SU, the free version lacks a feature or two but the customer support is the same.

I use both products, although I use SU a lot more than Fusion. I do architectural type design in SU and product or object design in Fusion.


Title: Re: Fordson tugger hoist
Post by: Hauk on November 07, 2018, 05:27:15 AM
Here are a couple links to some more info on the subject:

https://knowledge.autodesk.com/support/fusion-360/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-activate-start-up-or-educational-licensing-for-Fusion-360.html

https://www.autodesk.com/campaigns/fusion-360-for-hobbyists

I am very happy with Fusion360, but I must admit that I am a little worried that Autodesk might change their licensing policy in the future. I would hate to invest a lot of time learning Fusion360, and then be forced to pay for using it.

Building a user base by giving the product away or selling it cheap and then jacking up the prices to cash in is an all to familiar business strategy. Photobucket is just one example that comes to mind.


Title: Re: Fordson tugger hoist
Post by: finescalerr on November 07, 2018, 02:35:15 PM
Thank you both for those posts. After looking over the first link, Havard's point about AutoDesk's possibly giving away its program for a while and then maybe hitting us with an annual fee after we're "hooked", is exactly what worried me in the first place. When Adobe went to a subscription-only policy, I refused to do business with them. I kept the Adobe programs I own and, if I need a new feature, other companies' products are available.

As for SketchUp, I spoke to a subscriber a couple of years ago who uses 3-D CAD daily for work he does for Hollywood movies. I think he uses SolidWorks now but it's worth reporting what he told me because it reinforces what Greg and Havard say:

He thinks SketchUp is an excellent program and even devoted a lot of time to learning it in classes and working with it professionally. From a professional standpoint, it may become a little clumsy if you need some plug-ins to make it do what SolidWorks or Fusion360 do natively. SolidWorks also handles certain kinds of shapes more conveniently. An example might be Chuck's Fordson manifold.

SketchUp's inconveniences may be more important to professionals working against the clock than to hobbyists.

The bigger issue for most of us might be the threat of corporate blackmail: Do you want to use a subscription-only program, even if currently free, or one you actually possess and may reinstall on a new computer or hard drive?

Russ


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on February 06, 2019, 12:12:48 AM
All of this is interesting since I will likely lose my access to Solidworks in the future. There is one called On Shape that looks interesting, but still has the risk of commitment since I think it is only cloud based.

On another note, It took a while but I finally finished the mods to the Danbury tractor body. It was hard to do another one, but I think the new 3D printed parts will be more interesting to work with. Hopefully it will start to progress faster.

Post by: finescalerr on February 06, 2019, 01:49:21 PM
For some reason our annoying forum software reads photo resolution and size rather obtusely. If you have a photo editing program that allows it, try to set a somewhat lower resolution (e.g., 72 dpi) with a larger corresponding image size and make sure the total file size remains below 230kb. Photoshop doesn't seem to do that well but I bought a $50 competitor called Affinity Photo that does permit such manipulation. Much less frustrating that repeated attempts with my senile version of Photoshop. -- Russ

Eric, I am posting links from a photo site (Fotki).

Some progress on the tractor body:

I sponged on JB weld to simulate cast texture and to cover the metal for better paint adhesion. Then light sanding and Mr Mahogany surfacer base coat. Then hairspray airbrushed on straight from the bottle, Then a chip thickener coat of Tamiya TS spray paint (for larger scale subjects). Then Tamiya XF- Royal Light Grey. Chipping has commenced, softening with water and picking at the paint with a plastic toothpick. The Tamiya paint chips very well.

For me Chucks work is a phenomenon. I will be honest: At first sight all I saw was a pinkish engine piece with some heavy chipping - not very spectacular! And I remembered the same thought I had some time ago at post 94 of this thread. 
To me it seems, Chuck knows exactly what is of importance at that very moment and is not afraid of doing steps, I would never dare to do. I have reflected on my modelling and came to the conclusion that I have always the right balance at every moment in mind and so most likely miss some very important extremes that are important on the way to such a results Chuck can archieve. Hmm, very difficult for me to explain in English... :-[

Painting and weathering is always daunting to me.  It's fun when it works but it often doesn't, so I plan to fail. The initial coats will sluff off nicely in a vat of Windex. The weathering is done with pigments and Prismacolor pencils; both things that can be readily altered or removed. I also tend to paint and weather items separately, so If I don't like something I can strip it or whatever before I add it to the model.  The tractor body is the single largest piece, so finishing it (and liking it) will be a big step.

I am finally beginning to add parts and start the weathering process on the tractor.  I’m starting on the rear half first. The footrest and the dashboard/steering box are 3D printed parts.  I am using Prismacolor Premier pencils, Oil paints, finely sifted real dirt and Bragdon weathering pigments. Fortunately, the Fordson tractor could (and often did) leak oil out of pretty much every seam and joint.

Now that Nick has thrown down the gauntlet, its time for him to show all of us how it is done.  I personally want to see 1/32 scale working spark-plugs from him.

Hi Chuck - The Prismacolor pencils  "me being a bit thick in this area " can you give us a brief description of process of using them in conjunction with the other bits e.g. oil paints and Bragdon pigments how do you start ? to achieve this amazing finish !

and Im sure a few others !

Thanks very much! Nick, have a good trip!

Barney, here is the pencil process:
I smear wet Prismacolor pencils on squares of 320 grit sandpaper and let them dry. I pick up this “paint” with barely dampened cosmetic sponges and dab them on the base color. The first ap is a fade coat that is then sealed with Dullcoat. Then an ap of mixed grey mottling and seal again. The pencil coats are pretty transparent and work well over the textured surfaces (done with JB Weld). I also use my mini sandblaster with baking soda on LOW pressure to dull the often not-so dull Dullcote seal coats.

Continuing the oil and grease, using oil paints, fine dirt and pigments. 

I mix the dirt with the brown and black oil paints and apply with a brush in a thin coat. Then I use a cosmetic sponge to tamp in some pigments. This is a back and forth process until I am happy with the look.

I installed the ignition magneto. This is an aftermarket style that replaced the troublesome Model T trembler coils that came from the factory. I didn’t want to repeat all the same details I did on the last Fordson.


(https://media.fotki.com/2v2ETB9HNxU6NJ5.jpg)
Designed in Solidworks and printed by Shapeways in their smoothest detail plastic. I cored the parts for a .030 brass wire to strengthen the fragile material.


(https://media.fotki.com/2v2ETB9ejxU6NJ5.jpg)
There are grease cups to keep this well lubricated. Sadly, the front side will mostly be hidden when the radiator is installed.


(https://media.fotki.com/2v2ETB9Z8xU6NJ5.jpg)
The screws on the magneto caps were made from Tichy model RR rivets with the screwdriver slot cut in with an Xacto.

Thanks very much! Russ, this is just the FXD material with a different name. They have dropped the FUD/FXD names for some reason.

Bill, unfortunately no. The parts require sanding/ scraping to get rid of the print lines. I consider it a form of "sweat equity".

Title: Re: Fordson tugger hoist
Post by: Chuck Doan on June 16, 2019, 09:25:35 PM
Thanks Gordon!

The steps:
Primed with Mr. Surfacer black spray.
Applied thin ap of Rub N Buff Silver Leaf, and when dry, I, um, buffed it.
Then coated with Dullcote and soda blasted at low pressure (with my mini sandblaster and baking soda) to start to reveal the black, but just. Had a coupla do-overs here.
Then lightly cosmetic sponged Prismacolor pencil paint White and sealed again with Dullcote.

The (I assume Bakelite) distributor cap was painted with a grey/black mixed Prismacolor paint and then dusted with Bragdon pigments.

The grease is brown and black oil paint with fine dirt mixed in. The natural sheen of the oils can be left as is, or dulled with a touch of Prisma paint or brought up more with drybrushed high gloss.

Prismacolor paint is a wet pencil rubbed on a square of fine sandpaper. You can use it immediately as paint (brushed on) or let it dry and then pick up with a damp cosmetic sponge for subtle applications. I usually tear off a small bit of sponge and hold it with tweezers. EDIT: I use the Premier version of the pencils for this.


Title: Re: Fordson tugger hoist
Post by: Dave Fischer on June 16, 2019, 11:58:33 PM
Chuck-- I am SO glad you are willing to lay out a step-by-step on these techniques The Prisma paint is a great idea-- is that a standard Prismacolor pencil (the somewhat waxy, thick-leaded one) or the Prisma watercolor pencil? I remember back in the good old days of illustration using rubber cement thinner on a soft brush to soften and blend Prismacolor pencils over a painted background... works quite well and easily controlled, but rubber cement thinner is getting awfully hard to find (and WAY more expensive). I'm also wondering if anyone else can SMELL the dirt and oil on that engine?   DF


Title: Re: Fordson tugger hoist
Post by: Chuck Doan on June 17, 2019, 10:56:05 AM
Good point Dave. I have tried both types of the Prismacolor pencils, but I find the Premier pencils work better for me than the Watercolor (the Premier pencils are also water soluble for those who haven't used them). I hadn't heard of the rubber cement thinner method, could be a bit too potent for my workbench area! FYI, Bestine is back on the market after a couple of years of being out of production. I use it to clean the Shapeways FUD parts.

Thanks Frithjof!

After riding out a couple of rolling earthquakes this weekend, I got back to work. Two more bits applied. First was the seat spring. I made a forming buck out of brass strip, and clamped a piece of styrene strip to it. Then a quick dip in boiling water and a nice formed part is made. I wanted a styrene part because I hate painting metal.

The steering wheel will be missing, so I 3D printed the splined shaft that would be left. (printed by Shapeways)

As usual, more real than life. Great work and most interesting to follow. btw, with a good metal primer, painting metal is as easy as painting styrene. (Which I don't like... :D) And there are several ways to color metal chemically aswel;  But then again, I am the 'Wood Man '  ;)....
