IMO, just get correctly sized chain and the tensioners won't be needed. Once again, great job! Now let's try and see how you can make this better, since improvement is always fun!

EDIT: Madison, is there any way possible to make the attached file Mac-friendly? I can't seem to open it, and now that I've downloaded it's like waiting for a game hint 4 days before kickoff!

The C-Base makes it impossible to adjust the center-center distance between wheels, so while things are an even number of pitches between wheels, the gearbox isn't an even number of pitches without shimming it upward some. This might be fine, but the tensioners also up to get the chain away from the floor; it isn't always necessary to do that, but I try to do when I can.

What software are you using to to open the STEP file? STEP should be a platform neutral format.

IDK why, but my Mac says there is no application available to run the file, and I have A LOT of applications.

OSX doesn't really have a good program to open STEP with.
You generally need solidworks, inventor, ProE/Cero and none of those are for mac.

Can it be made into a PDF, or does it not work that way?

It doesn't work like that.
You need a CAD program as Madison said.

Try ida-step. Its not fantastic, but it does let you view universal .stp CAD data on a mac.

This may be of some interest.

Well, it's a CAD model -- so you'd need some variety of 3D CAD software. Solidworks, Creo, Inventor, CATIA, etc. should all open it without trouble. AutoCAD probably can't; nor can SketchUp. I am not sure about VectorWorks, but it's not really built for the mechanical design market, so who knows.

I'll see if I can't make a 3D PDF. I haven't tried that in awhile.
