This project is a homemade feather plucker. I had an old homemade bench-type grinder laying around in my basement, and figured it would be an easy conversion to a plucker. I bought a 4" PVC cap, then drilled and slotted 16 evenly spaced holes in it. I also bought 8 rubber bungee cords and cut them into 4" end sections (16 total). I threaded each bungee section through the slots in the PVC cap, and drilled a 1/2" hole in the center of the cap. After removing one of the grinding discs from the bench, I slipped the PVC cap onto the shaft. I retained the washers that were already on the grinder, and they worked perfectly to stabilize the cap.

The old grinder setup...


PVC cap with slots cut in them. The cap wasn't as tall as I'd like, so I staggered the holes so there would be enough plastic left for strength...


PVC cap with 4" bungee cord "fingers" mounted on the grinder shaft...


I installed a light switch on the other side to turn it on and off. Here's a short video of it running...

I finished by adding a piece of plywood over the top to keep the motor and belt feather-free...
