I have the 12x33 HF lathe. It's fine for most uses but turning larger platters and bowls just takes more than the motor has to give. I am not familiar with the name of the motor mount it uses, but it for certain isn't the NEMA 56 mount. This thing mounts from the nose of the motor (not the strongest of mounting points).

I'd like to upgrade to a 1-3 hp motor using 110v. If I could get a DC motor in that power range with a speed controller I think I'd be so happy my wife would not recognize me.

So, if anyone has a source for motors for this contemplated upgrade, now would be a good time to speak up.

I have some suitable DC speed controls, but no suitable DC motors

Personally I don't think it is such a good idea. Converting to VS DC is one thing. Increasing the power is another. The whole lathe will have been designed (one would hope 'designed' is what happened) with certain limitations in mind. Cost of manufacture was probably high on the list of priorities, which most likely means cutting corners and using the bare minimum of materials that will perform the specified tasks, under hobbyist conditions, and only until the warranty expires. Ever notice how lathe manufacturers never give any info about the weight their lathe can drive, or how unbalanced it can be?. Most likely to go will be the bearings if you try to drive something too heavy or out of round.

So by all means add a VS motor. They are a pleasure to work with, even for small spindle turnings, but think twice before you use your lathe to turn lumps of wood beyond its designed capability.
