The shirt compresses to about 2/3 of its normal diameter for an effective shot (independently tested with the first shooter stage and second shooter stage, but not together). The wheels do not mark up, although a few cloth fibers sometimes gather after several shots.

To clarify, I've already built this device. There's a bit more wiring to do before it's ready to test in its entirety. Indexing with the ratchet and pawl is functional. The total price of the unit is approximately $350.

That's awesome then! Do you have any videos of it shooting?
