We built a very similar intake this past year but powered the rollers off of the upper feed system (to reduce motors and save weight), and direct-drove the angle-adjustment motor by internally coupling it to an extension inside the roller.

In retrospect it was way over-complicated and this looks like it would have been a much simpler (and easier to maintain) way to go. :rolleyes:

Where can I buy the pulleys that are next to the intake wheels and the belt/tubing thing that rounds the pulleys?

That tubing is called polycord (or Urethane Belting if you actually want to find it). McMaster (http://www.mcmaster.com/#round-belts/=13he34i). I am guessing that they 3d printed their pulleys.

We made the pulleys ourselves using 2.25" acetal that we got pretty cheap from a company in our town. We have access to three lathes and eager students so it wasn't too time consuming. We cut them to length, turned down a groove in the center to fit the cord, bored them to 1/2", and then hex broached them.

Looking back I probably would have just done what 188 Blizzard did which was use the Colson wheels as their pulleys. https://www.youtube.com/watch?v=UOMRgVIzI0M

That's the stuff. We used the 1/4" round solid core tubing.
