Topic tags/keywords: craftsman wood lathe model 351217170

This model of lathe has an electronic speed control that has a high failure rate, and is no longer available. A treadmill speed controller can be made to fit with a small amount of modification. Caution the voltage can kill you. If you do not have a background in electronics you should not make this change. A mc-60 speed control from several different places, a 5k linear taper pot, and a choke also from most treadmills worked in mine. Some slight modification is needed.

Can you describe the changes you made to the LATHE.. I have one and have found that the drive power reduces as i try to cut..and if pushed too hard it comes to a halt. Maybe this change you have suggested will make some difference.
Thanks

I had to cut 3/16 inch off the end of heatsink farthest from the large transistors. Then if the resistor marked rps on same end is not cut out of circuit, it must be. I used a 5 k reverse taper pot from digi-key kb5021s28-nd. I also installed a choke that is used in treadmills (common part for most are the same. The motor wires are marked, but check direction of rotation, and if wrong just reverse the motor wires. The a.c. input is marked white and Blue. The blue wire is the black in U.S. Caution I accept no responsibility for safety. Only you can decide if you are qualified. The voltage can be lethal. I don’t know if you can get by with the 10 k pot that is in the lathe for testing or not. You can do without the choke, but it should be smother when it is installed. It just goes in series with a motor lead.I got the controller and the choke from Century Service co. 1-877-627-0349 Once again Please use Caution. 120 volts can be fatal.

Thanks .. Any other relevant info you can give would be appreciated..This should get an electrifying result though..( Sorry British humor) I am very cautious with electricity as in England its 240 volts not 110 its a little more hair raising..
Thanks again. Maybe I can try this before I throw the thing out..

Ps do you know if this motor and its structure will allow it to be reversed?

If it is a two wire motor, it should be ok. If you are not in the U.S. and it is a 220 volt motor, then you probably have to have a 220 volt treadmill controller for it to work correctly. Also, the wiring is essentially the same as the original in respect to the potentiometer. I am not familiar with other than a motor rated at less than or equal to 120 volts. I don’t know how the U.K. handles a 220 volt line, and if it is a d.c. motor rated at more than 120 volts. I assumed that if the lathe model number was the same as mine, that it would have to operate at 120 volts. But I have been wrong before.

Sorry I forget to mention I am running a 110/120 motor.. So I hope to be able to reverse the motor for sanding and other things that need a reverse..Thanks for the info…The motor should be the same as the one you have..

If you are using 220 volts input, unless you have a motor controller that is rated at 220 input, it will fry. Also it has to be a D.C. motor for the lead reversal to work. If it is an A.C. motor, all bets are off.

Is there a 3rd party source for the electronic speed control (circuit board(?
