Here is a video of a setup that I built a couple of months ago.
I had run across this compact 120 volt DC motor and I thought that it might be useful for something. I did some tests on it and it had plenty of power to use as a power source for shaping cork. I estimate that the top speed of the motor is about 3,000 rpm, but I can not verify that for sure. I made a heavy aluminum base plate for the setup and then bent up a piece of aluminum to form the motor mount that I attached to the base plate using rubber isolation grommets to reduce motor vibration to the base plate. I used XL pulleys and an XL belt to couple the motor power to the head stock shaft. I happened to have an AC power variac sitting around that will change the ac voltage to the load from 0-130% of nominal. So, I can regulate the 120 volt ac wall voltage from 0-about 135 volts. After the variac, I added a full wave DC bridge to convert the AC voltage to pulsating DC voltage. Then, I put on a filter capacitor on the final load to smooth out the pulses for a good dc voltage that could be varied from 0-135 volts. I estimate that the power from the motor is about 1/3rd - 1/2 hp. i.e. plenty of power to spin a rod or mandrel to shape a grip. [www.amazon.com] Re: DC motor - taig head stock - Taig Chuck

Nice. Looks like a lot of torque when that motor starts up. Re: DC motor - taig head stock - Taig Chuck

Lance,
One big advantage of a DC motor and that is torque from 0 to maximum speed. The 2nd thing is the advantage of easy speed control on the motor. Sorry, only registered users may post in this forum.
