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.

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.

Looks fantastic Chuck!  The little details like the builder's plate really make a huge difference in the overall effect.

Fantastic work , as always , Chuck ........ Very inspiring for us mere mortals  ;D

Thanks for the info on grease and wear &  tear on the gears might well come in useful to me shortly

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.

Chuck, Sacré noir! The wire rope looks well oiled. Glad to read you are really enjoying this project, I'm really enjoying seeing it.

It is the subtly of your work which is the real joy to look at , that and the accuracy of your observation ..... The way the inside of winch drum is rusted being a great example . Lovely just lovely


p.s. Thank for info on the wire you used, managed to track down some 0.8mm dia stainless steel wire in the UK which should work for a 1/35 scale project

Most excellent Chuck!  I echo Mr. Fergusson's comment on your observational skills.  This is the key ingredient in making the model believable!

All those little details. Your the master at making them look so real.
As always exceptional work.

You are really one of the best modeler I've ever seen!!!

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.

Actually I am a much better modeler than Chuck, and quite prolific, but far too modest to post my work. Chuck and the others are aware of that, of course, because I taught them everything they know, help with the detail work, and do all the final finishing. Their nickname for me, in French of course, is le menteur. If you don't know the translation, you should look it up; it's very flattering. -- ssuR

 "Le Menteur" . That is one of the many nicknames they have for you . I rather favour an even more flattering nickname :

   " Le LegEnd " !

You're right, he's not too bad. Looks like he models in about 1:12 scale but I couldn't find any verification. -- Russ
