I am making a small mini-gun from scratch, and have run into a little snag.
Since I need only the barrels to spin. I've made the barrel assembly out of 1/2" CPVC (Barrel) and cut spacers out of Acrylic sheet. I also have a center support / bearing made of 3/8" PEX tubing slid over a 5/16 threaded rod (sorta like a sheath) that attaches to a spacer and travels through the barrel base into the drive train area.
I was able to re-purpose a 12v (RS-385SA) motor out of an appliance. It has a 10-point gear which looks to me, to be press fit to the motor shaft. A quick Google search mention that the RPM is about 14500-17500 RPM. I tried a wooden pulley rubber band system, by having a 2 1/2" pulley and a 1 1/2" wooden pulley press fitted on the 10 point gear. It worked with very limited success, dislodging the rubber band within a few turns.
I think a mate for the 10 point gear might be the best way to go. Does anyone know where I might be able to find a 2 - 3 inch plastic gear or something.
If you have any information, ideas, comments, or suggestions I would look forward to hearing them.
Thx
