I was given a Jet 1442, RIGHT AFTER I’d bought a nice Nova.

I sold the Nova for a bit more than I paid for it and stuffed the money in a can.

I still have a Jet mini lathe with a nice stand and drawers and a working big old Delta 46-450 with new bearings, both of which I plan on selling. I’ll put that money in the can too.

I like the 1142, but it’ll only go down to around 400 RPM. Pretty fast for some lumps of wood. As such, I’d like to swap the head for something akin to the nice Powermatics.

Anyone know of any possibilities regarding such a swap?

Can you post a picture of this delta lathe you have. I have a 46-450 head stock casing and spindle that’s not going to be used. ............. Jerry (in Tucson)

I also have a Jet 1442 and would like to be able to go lower than it’s lowest speed of 400 RPM.
Any practical ideas out there?

This is what the 1442 looks like. I, also, have a 46-450, though it’s disassembled right now, for paint.

If the bed is the same I’m guessing the headstock (you’d also need the taller tailstock) from a Jet 1642 would be a direct swap. Most of the lathes I’ve seen modified for electronic speed control have had a 3 phase motor and a vsr to control it. Whether there’s something that would adapt to yours, I don’t know.

You could add a VFD to your head stock and be variable speed that way.

I have the Jet 1642EVS and the speed control is one of my favorite aspects of it.
All the way down to 0 rpm.
