Yeah your probably right. The one picture linked above by fr05ty27355 pretty much shows it as well as the picture that I have.

It shows the pulley setup pretty well.

The top and bottom plates on the wheel part of the shooter are 1/8" waterjet AL. We had to find high speed 1/2" diameter bearings for the top, which are pressed into the bearing blocks on the top plate. The lower bearing are 5/16" diameter. I would of prefered larger, but I wanted to try to not add the weight of additional bearing blocks on the bottom too. So 5/16" was the largest we could go and still meet the RPM requirements (+10,000 RPM). So far so good. We lost a couple lower bearings on the practice bot, but I think those were more from being installed incorrectly.

I am planning to create another Tech Notes as soon as things with the robot settled down. Hopefully, I'll get a chance to do that sooner rather than later.
