« Part 1: Delta 14-651 Mortiser Switch Reliability Part 2 of Tool Reliability... series no next part

Not sure, but I think I’ve had this for about 5 years now. The lathe doesn’t spin up right away. Sometimes it doesn’t start and other times, it starts but turns real slowly for a while, then speeds up to full speed. It also seems to lack power when I do get it running.

It has a DC motor 1/2 horsepower, 120 VDC, 60 Hz, Class E 1700 RPM.

I am assuming that the speed control has gone bad, but can’t be sure. Here’s a photo of the circuit board.

Has anyone else had this issue? Is there some kind of industrial strength replacement for this board that I should look into?

Have you called the guys at Penn State? I have the Turncrafter Pro, which is similar but much older than your lathe. Mine is not variable speed. The ONLY issue I’ve had is I broke a belt. When I called Penn State they were very helpful and quick-shipped three new belts to me at no charge. My lathe is about 8 years old now. I’ve done a lot of turning on it and I love it.

Yes, actually, I’ve ordered the VS upgrade kit from PSI. It’s usually sold for the lathe you have Ron, but contains all the parts including the speed control and a backup motor, that replace the parts on my lathe. If the speed control was the problem, I’ll see if I can get a rebuilt one from them so I have a spare. I was mostly looking to see if others had had this same problem.

So I received the VS upgrade kit which included the motor and speed control that are identical to the parts on the lathe. I replaced just the speed control and now it runs fine. I think I’ll get back in touch with PSI and ask them to offer just the control board which should be cheaper than the $120 I spent for the kit.
