Fordson tugger hoist

[Chuck Doan]

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.

Chuck, that's going to be an exquisite model. Please keep us up to date. Your drawings are just superb! --  Russ

Hi Chuck,

Simply great design performance.

Just how is this to be solved with the roller chain or will it remain motionless?

[Bill Gill]

"CHUNK" away, Chuck! This will be another good one to follow along.

When I saw this thread this morning I became dizzy by such marvelous engineering work. In contrast, one feels like carving wood with a Swiss Army knife 
Very, very ... very inspiring work!

[Chuck Doan]

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.

Chuck-- For those of us who like things that bolt together, THIS thing is downright pornographic. There is a little of everything! What do we have to do to speed you on your way? It would be great to include a representation of Mr. Do-Right from the ad photo-- ever seem a CLEANER lumberjack?  DF

"I will probably test the rotation anyway while making motor sounds...."

That may be the funniest hobby related line I have ever read or heard.

What a way to start the New Year off...

Your usual excellent drawings and research.

Question will this need a gas pump along side it for fuel?? 

Jerry

[Chuck Doan]

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

People often say our models are toys...that doesn't bug me, but what does is that I don't get to play with them!

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

[Chuck Doan]

Thanks Rick! The Skagit sprockets are designed to re-use the splined bushing that normally mounts the rear wheels.

Fantastic! I've been wondering what you were up to lately and when we'd be treated to another of your fascinating builds, so I'm very glad to see this.

[Hydrostat]

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 ...

Cheers,
Volker
