1953 Ford standard transmission (1/3 scale)

[gbritnell]

Trying to fill up the winter with projects so I took my CAD drawings for the 1953 Ford standard transmission and made Solidworks models for all the parts. My CAD drawings are meant for machining from metal so changes had to be made to make them printer friendly. Things like shaft to hole dimensions, ease and assembly of printed parts and the big one for me making the parts so I don't need as much support material.
Anyway, I'm happy the way they came out. You can even shift gears albeit carefully.
The trans is a 1/3 scale model of the real thing. About 10 inches end to end. I started with PTEG, not my favorite but initially everything was going fine then my Ender 3 Neo decided it didn't like the PTEG so I switched to tough PLA.
The problem with the PTEG was that flat surfaces on the build plate would curl up at one corner. I tried adjusting temps and feed rates but no luck. The build plate was level and clean with just a hint of hair spray. The PLA has to be knocked of when cool so I know it's not that.

That is a most impressive 3D printing/design project.
Very nice.

Are you planning to machine the metal parts as well?
I saw that a while ago. Thought that would be a nice project to make, but It is too much challenge for now. Making the housing seems to be the most difficult part.

Is the function of this straight gearbox similar to your model?

Are you willing to provide/sell the STL files? I have a MarkForged printer that uses a very hard medium that could work very well here. It doesn't get much use, so having a fun project would be interesting.

Hi kvom,
I'm putting together a build information sheet so soon as I get it together you can send me a PM for my email address and we will talk.

Looking good!
Did you also make a model with straight cut gears?
Also how does one make the gears end up on the same centre to centre distance?
I did try to make a cad model of the webster and I think I followed the gear specs quite well.
But the gear axles didn't end up I the same place as in the drawing...
Doesn't matter much in that case but for a transmission that wouldn't work.
