Not quite sure if this fits here, but I couldn’t resist posting. My wife is undertaking a craft business opportunity where a lapidary table will be essential for her to have. So after researching how much they cost and about having a heart attack in the process I did a little research of my own and decided I would make one myself. So I’m going to use a 2 HP DC permanent magnet motor with the controller and everything else to power the plate of this thing. If it works well, I’m going to figure out how to make a small lathe with the same set up.

Has anyone else had any experience with the DC Permanent magnet motors?

You might look at a 3 phase motor with a VFD.

You can get a 2hp VFD for about $120 and a used
3 phase 2hp motor for almost nothing. The VFD
can make it do all kinds of speed tricks.

I looked into that also. I may consider that if I end up doing a lathe. But I was able to get the 2 HP motor, transformer, controller and switches for 120 bucks.

If this doesn’t last and burns out I may look into the 3 phase motor and VFD.

That’s a good deal. A lot of turners were using DC
motors up until the VFDs started getting a lot more
affordable.

I have a couple of small DC motors with gearboxes and
variable speeds but they are low power feed motors,
maybe 1/6 hp max.

Dunno about the motors, but there are plans for a small lathe in Shop Notes #73. Other than hardware, it’s pretty much built out of one 5×5 sheet of 3/4” ply.

I suggest not reinventing the wheel on the highly machined parts. You can pick up replacement spindles that will have the Morse tapers already made. I picked up a replacement spindle for my model metal lathe for under $40. A pair of matching pillow blocks ($8 each) and if I needed to, I could put them together as a lathe from that and just about any motor.

The regarding the DC vs 3ph + VFD. With a 2 HP dc motor, the controller and power supply will be a much more expensive route. At 750 watts = 1 HP, that is a serious DC power supply. I had picked up some smaller DC motors on the cheap before realized it was much more expensive that way.

Yes I agree that that the controllers are expensive. I was fortunate to find a complete set for 120 with shipping.

Thanks for the info on the lathe parts, I will definitely keep that in mind.
