Title: Logging Arches
Post by: NORCALLOGGER on October 27, 2013, 08:34:50 PM
Hi all,
Have been meaning to get these built every since I finished the Cat 60's a couple years ago.  It has taken quit a while to run down enough prototype information to satisfy my mind about the build.
Anyway finally getting a start and thought somebody (besides me) might be interested in the process.


This arch is located at Collier State Park in Chiloquin, OR and is a modern (1930's) all welded Fairlead Arch with Athey Truss wheels.  I have no idea what the extra framing on top of the boom is all about, some kind of a later years adaptation for a use other than logging arch I assume.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch0.jpg)


This particular arch caught my eye because of its wide stance, look at the width of the cat tracks in the background, it could carry a 5 foot diameter log with no problem.  That width probably took some getting use to by the "Cat Skinner" before he quit hanging a track up, probably a good thing those Athey tracks were flippers.

Anyway I will get some build pictures up soon.
Later
Rick

I'm looking forward to watching this build!

Did you get pics of any of the other equipment there? Looks like they have some cool old crawlers.

Ray,
I have taken lots of pictures at Collier through the years and took a bunch more on this last trip.  I posted a few over on LSC but they didn't stir much interest so I didn't post any more.

Anyway on with the build.

For some reason it seems like I always start with the wheels on most any build project, I think it is because I like playing with the lathe.  Anyway for this build I used ¾ inch PVC pipe and turned it down to the required inside and outside diameter and cut a shoulder in that the spokes would mount into.  Duplicating the first one 15 more times was a bit tedious but they all came out usable, well, 16 out of 21 ain’t too bad.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch1.jpg)


The “Athey Truss Wheel” for the actual wheel part has a 9 spoke layout between hub and rim.  This took some head scratching trying to remember how to lay out a regular polygon in a circle that wasn’t an oct or hex.  This layout works for any un-even number of points with all sides of the polygon being equal.  I can give an explanation of the diagram if anyone is actually interested. 
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch2.jpg)


With the 9 point polygon laid out on a jig piece I cut .020 styrene to use as a base to weld the spokes to.  I decided to use a stock ½ round styrene shape as the spoke as nothing in a triangle shape matching the prototype was available.  By using the backer piece it allowed me to tie the hub and spokes together in a solid unit.

Well that's it for now, thanks for taking a look.
Rick

Rick, great to see you back building and posting.

Already reminds me of your crane build, learnt a lot from that and sure will do so again from this build.

Looking forward to the next instalment

Rick,

I'm looking forward to your build of the arch. Collier Park is a great place. We go back to the late 1960s.  I used to communicate with Cap who started the collection. After he died is started going down hill with a minimum of upkeep.  I have photographed many of the pieces and have built three major pieces based on those measurements.  It was sad to see it going down hill however almost at the last moment it is getting attention and several pieces are in restoration. It has been many years since I was there but they now have a couple of rangers on duty there. A good place for research.

Bill

Hi Gordon,
Thanks for the nice words.  I have been busy building all along just not much that would interest folks on this site.  Mostly just "durable" builds that will hold up to some handling and the outdoor use.  Did just outshop my 3 truck Shay that came out pretty good but is only semi-weathered so of no interest here.

I have been following along with all of your adventures posted here, most excellent work young man!!!



Hi Bill,
I was never fortunate enough to meet Cap but have sure heard a lot about him through the years. 
Yes the park went pretty far downhill before rescue, which is surprising for an Oregon State Park as they are so well known for their excellent facilities.  But, the last 2-3 years has sure seen an upswing in care and growth for the park.  As you say they have rangers on duty as well as docents, and a fully staffed gift shop.  Equipment being cared for and restored as well as new buildings being built.  You should go down and see their new "dining hall" museum building its really great.

We like to go up and stay at the RV park across the road, great place to spend a few days visiting the museum, fishing and hiking, and running down old rail lines and logging sites.

Speaking of old days I went up there 2-3 times years ago and met Bill Roy and we would measure and photo equipment, and BS the day away.  Now there is a guy I miss talking to, oh well.

Later
Rick

Rick,

The last time we were there we stayed at the RV park. But it was soon after the snow melt and I got eaten up by mosquitos.  I'm now nearly 82 and had to give up my motorhome because of bad heart and knees.   It is a long drive from Eugene to there. I would like to go back up there again but the wife doesn't want me to attempt the drive alone.  I am hoping I can talk my son into taking me up there next summer.

Yes I really miss Bill Roy. We did a whole lot of work together putting out kits. I did most of his early castings.  We were up to the park a couple of times  and up to sisters and Redmond for horse drawn equipment auctions and sales. Every once in a while I find myself starting to reach for the phone to see if he can have coffee.  Was a big loss.

I started the metal spoked wheel arch. Made the patterns and built the wheels but never got any farther.  Maybe I can finish it in plastic.  I'm happy to see some one doing logging equipment.  Keep it up.


Title: Re: Logging Arches
Post by: NORCALLOGGER on October 31, 2013, 09:27:35 PM
A little more work to show.

After the hub and all the spokes are glued to the .020 disc they are trued up in the “poor man’s mill” to fit into the recess cut into the wheel rings.  The .020 backer is then cut out from between the spokes leaving a solidly constructed wheel center.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch4.jpg)


This picture is just showing an assortment of pieces that went into the wheel construction.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch5.jpg)


A set of completed wheel “rims” set in the track assembly and held in place with the wood block.  The track is an extra set I ordered when I built the Cat 60’s, they are not really correct for the Athey Truss Wheels but more on that later. 
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch6.jpg)


Question; what glue, preferably a welder will work to attach Styrene to PVC?  The welders I am using, Bondene and ProWeld, will attach the pieces but they are easily broken apart so there is no true bond there.

Thanks for taking a look.
Rick


Title: Re: Logging Arches
Post by: Ray Dunakin on November 01, 2013, 01:12:19 AM
Looking good! Nice work on those spokes.

I use Weld-On 16 for gluing styrene to PVC. It's not a straight solvent type, kind of syrupy, but it works well.

Really neat project. Looks like it's off to a running start. Really looking forward to following along on this build. Like Gordon said...there is so much to see and learn from your builds.




Title: Re: Logging Arches
Post by: NORCALLOGGER on November 03, 2013, 10:09:43 PM
Thank you gentlemen for the kind words.

So I'm Back with a little more progress. It has been a fun build so far, trying to engineer from pictures is always a little problematic.  I always find a few spots where I scratch my head and think "why didn't I take a couple more pictures or measurements in that spot while I was there?"


The “Athey Truss Wheels” did not have cleats on the track pads so obviously the “cat” tracks had to be altered to make them at all usable. I found that I could mount the track section in the drill press vise and hold them reasonably well while I ran them through the mill and cut the cleats and bolt heads off.  There was quite a lot of variance in the cuts because each individual pad would be held tight or not so tight depending on the part of the casting clamped in the vise.  I only ruined 3-4 pads but they are easily replaced and when all done everything had to be hand dressed with a file for uniformity anyway.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch7.jpg)


The completed “Athey Truss Wheel” assembly with the axle beam in place.  The tracks look alright on there but they are definitely not a reproduction of the original.  I just don’t feel that this project warrants fabricating a master, casting 96+ pieces, then assembling them to get a finished product that will look so similar once painted that not one in a hundred will know the difference anyway.

(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/arch9.jpg)


Thanks to all for the tips on glue for the Styrene/PVC connection.  I was able to get a can of the Weldon #16 that seems to have really done the job.  I remember using this stuff several years ago and found that once you open the can the shelf life is very limited due to rapid evaporation.   As for using PVC pipe joint glue, well, it might work fine but I have enough trouble trying not to make a mess without using that stuff.

Thanks for taking a look, more to come.
Rick

Rick,

this looks good to me. I especially like the worn touch resulting from filing all parts individually. Are you going to burnish the tracks?

A lot of people are counting rivets, but maybe never have seen any used machinery in reality (or even worked with it). There are so many possible changes in the life of an object. So if you don't want to model one very special prototype or do the modeling for preserving, museal or educational pourposes you can make a lot of compromises. It has to be alright for you.

Rick, do yourself and the can of Weldon # 16 a favour, go stick it in the door of the fridge.

Chilling it down just about stops the evaporation, the can will last for years if you do this.

Leaving it out on the bench, you might be able to find some in 12 months time.

Post by: NORCALLOGGER on November 08, 2013, 10:32:28 PM
Volker,
You are correct about the transformation of equipment throughout it's lifetime.  Hard used equipment, and it doesn't get much harder used than logging equipment, can become almost Unrecognizable as being from a certain builder after a few years in use.  Years ago we had an old New Holland wire baler that had been rebuilt and repaired so many times it was difficult to recognize it's origin. 

Greenie,
If you think I would be doing myself a favor by putting a can of glue in my wife's refrigerator I think you may be very much mistaken ;) :D

Anyway, another update, this project is taking much longer than expected due to the fact that real life keeps interfering with model building time.  I need to come up with some way to correct that, any ideas?

The angle arch was laid out and cut from ¼ inch Sintra and laminated between sections of .030 Styrene sheet.  In this picture I am drilling the holes for the “Athey Truss Wheel” axles before laminating on the edge pieces of .040 Styrene strips. 
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/archa10.jpg)


This picture shows the Truss Wheels mounted to check the axle bores and the truss wheel clearances before beginning the edge strips.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/archa11.jpg)


OK, for a way to anchor the vertical arch to the angled arch I had to stop and rethink the possibilities.  My original idea was to just use some Styrene plates glued to the angled arch and drilled to hold the vertical arch pin bolts, but I realized (in time which is unusual) that this could be a very weak point in the model construction.   So, after a lot of foot dragging I decided that there was only really one way to do it.  Route out both sides on the top of each arch leg and insert a brass plate that would tie the truss wheel axle to the vertical arch pins.  This procedure though time consuming (Sintra doesn’t grind worth a darn) is proving to be a very good solution. 



This view shows the edge pieces in place but needing the uneven gaps along the edges filled with putty.  You can also see the brass anchor plates that will hold the vertical arch in place once everything is assembled.  After routing out the areas for the brass connector plates I had to cover the mess with Styrene “patch” plates.  I don’t think this will be much of an issue, if you go back and look at the prototype pictures you will see similar plates in different places.

Just a glamour shot showing the tracks draped over the wheels and Ole Hansen, the shop foreman, getting another photo op.

That's all for now, thanks for taking a look.

Sintra is an American brand name for PVC foam board. There may be something similar under a different brand name in your country.



Title: Re: Logging Arches
Post by: NORCALLOGGER on November 13, 2013, 10:36:05 PM
Thanks all for the interest in this little project
I finally have some more progress to show.


I thought it might be a good idea to explain that I lay out each segment on card stock before transferring to styrene or Sintra sheet.  That way I can make all the mistakes and changes on the card and not mess up the styrene sheet.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/archa18.jpg)


Cutting out the .040 Styrene skins for the vertical arches, I have been using the E6000 glue to laminate to the Sintra.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/archa19.jpg)


Here is one of the vertical arches with some of the wrappers on and the holes drilled for the start of the wrapped cutouts.
(http://freightsheds.largescalecentral.com/users/rick_marty/_forumfiles/archbuild/archa20.jpg)


A couple of shots of the vertical arches completed and attached to the angled arches and tracked wheel assemblies.  The card stock beam pattern is in place to give some perspective and to make sure the measurements are correct.  Notice that the brass has all been burnished with A-West’s “Blacken It”, things are moving along.

Rick,

after thinking a while about your construction and comparing it with the prototype I feel there's something missing: starting from the arch closer to the dozer there should be one more hole to adjust the level of the tow beam. Otherwise the complete construction wouldn't need to have joints?

Looks very impressive (the structure and your modeling  :)).

Cheers,
Volker


Title: Re: Logging Arches
Post by: NORCALLOGGER on November 29, 2013, 11:09:55 PM
Hi Volker,
You are absolutely right on both counts.
Well actually there should be two adjustment holes in both arches for
changing the tow angle/height.
But as there is only one Cat model towing these the adjustment holes were not
a critical factor for me.
Thanks for the interest.
Rick


Title: Re: Logging Arches
Post by: Max Corey on November 30, 2013, 02:58:21 AM
Both the Cat and the arch are favorite models.  I only have the 1/48 Brommer Cat and arch and the dozer wants a blade.  Your scratchbuilt versions are wonderful.  Now all ya need is a log to replace the clamp.  If you can model a really good looking log (difficult and rare - probably a found section of tree branch would be best) I will be bowing before your awesomeness.

Hi Ray,

I apologize for the confusion. 
I Took an Idea from Aaron over on LSC and and turned a coupla of diecast John Deere crawlers into Cat 60's and as I look back at the information it was more than a coupla years ago, Spring of 2009 to be exact,  I did a build log on them on LSC or maybe it was MLS  but anyway it is all gone now.
Phil at TimberTimes was kind enough to give me a little space in his last issue (#53) to tell a little bit about the cat 60's and how I built the models.

Good luck with that search Ray,
I tried for a long time to come up with plans but had no luck at all.
Luckily I had access to original equipment that I was able to measure and
photograph, that was a great help.

Might check with these guys, when I was in contact with them back in '09
all they had were photos and specs no drawings.  Maybe they now have some.

http://www.hcea.net/Default.aspx?pageId=1493557

For photos get a hold of one of the Iconografix (photo archive series)  books
"Caterpillar Sixty photo archive" lots of good pictures.

If your ever in Sacramento go over to Woodland to the Heidrick Ag Museum
they have all kinds of crawlers and other equipment and aren't adverse to
letting you crawl all over a piece and measure and photograph (ask first of course)

Just the engine. Not too particular about whether it's gas or diesel. As for era, something "not modern" -- anything up to the post-war period, maybe even into the 50's, would suffice.

What I'd like to do is model it as the power plant for a mine or mill. I might also be interested in using one on a mine loco or critter.

Well you probably don't need my build pictures now to build an engine but damn it I finally found them and got them loaded so I am going to post them anyway :) ::) ;D
I will start another thread for them because someday I will finish the arches and use this thread for that ;).


By the way Gordon,
Is the flywheel on backwards on that engine?
the bar holes look like they are elongated the wrong
direction but it is hard to be certain from the views.

Rick, shows you how much I know about these engines..... I modified the kit's flywheel, had too many holes, but never thought of the direction of rotation.

Will add that to the other things that are wrong with it and that have been pointed out to me  :(

Hi Gordon,

I wasn't trying to be a pain.  I just happened notice that because I had such a difficult time building the ones for my Cats.  As it is I have only about half as many holes in them as they should have.

Later

No progress to report on my Arch project but I ran across this old film of logging operations that took place just up the road (60-70 miles) from here and there is some really excellent footage of cats and arches at work.

Take a look here.

No audio but none is really needed.

Wow, I knew that it had been a while but didn't realize that it had been 2 1/2 months.  Well I finally have them painted and weathered and am able to call them finished.  The prototype picture is of an arch that was built in the late 20's early 30's and what it looks like in 2013.  My builds represent the same arch but in 1939 and still being used so they are not quite so weathered and battered.


Everybody claims to like pictures so here they are, hope its not too many.

Thanks for taking a look.
Well, on to something else.
