Re: Re: Re: Buffing Machine Plans
You are right Don, to some extent, however since it is only a 6 inch wheel and has a nut in the middle, varying the speed is somewhat limited. That doesn't seem to be a problem for polishing cabochons and other small objects. The nut could be dispensed with by using a backup disk with a threaded 1/2 hole and having the disk spinning in the proper direction to keep the disk from spinning off the threaded shaft during use. Most motors can be reversed by switching a couple wires within the motor. The motor can also be turned around to reverse directions. The speeds can also be varied by changing the pulley sizes.
I am also building a flat lap that has a potentiometer to vary the speed. The plans for building the flatlap were posted at McRocks. Denise might want to consider building the flat lap since it can be used in many more different ways that just sanding or polishing small objects such as cabochons. However, to utilize the old motor she has, my cheapy design should provide a useful polishing wheel or sanding wheel. I keep a plastic cover over the disk and pad to keep it from becoming contaminated when not in use.
