Fordson tugger hoist

Your model is shaping up beautifully...could we expect anything else.  The 3d printing is amazing.

I am going to have to learn how to do the computer drawings o that I can get some decent manhole covers made.

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.

They came out pretty clean.

I see you started the sled.  I'm really interested on how you stain the wood parts.

DAMN!!!!!!!!!!!
Makes we want to build a steam donkey!
Thanks for posting!

The results look spectacular - and in such short time! Drawing and 3D printing is definive the way to go ...

(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.

Very awesome!

[TRAINS1941]

Very awesome!

I'll say!

Test fitted the chains tonight. Seem to fit.

Great project Chuck, love the use of 3D printed parts and the engineering involved.

[Bill Gill]

Chuck, this project is progressing rapidly and coming along well.
