Topic tags/keywords: lathe vfd

I’ve been turning for a couple of months on a 70’s Rockwell/delta, that I picked up for $225. It’s the type with four pulleys top and bottom, with a 3/4 hp 120v motor, 12×40
I was at a flea market type place last week and picked up a 3 phase 1.5 hp motor for $4.99!
Game on! I ordered the best reviewed cheap VFD on Amazon along with a keypad, a pulley, an emergency stop button and a 1-5k potentiometer. So now I’m at a little under 200 bucks for a much easier to use lathe
It went together pretty well, the motor was a tight squeeze, I mounted the VFD in the motor enclosure and put an air filter over the vents to keep the dust out
I tested it with a really out of round chunk of red oak and it did great!

Very nicely done.

You should do a blog with more details and parts used with links.

I’ve never done a blog but now might be the time, I had a hard time researching what to do so I’ll post everything I used later

Nice. It’s a good old lathe that’s now a better old lathe. Congrats.
