« Part 6: Over complicating things [updated] Part 7 of Goodell Pratt 125 Bench Lathe series no next part

Last update I had given up on the lathe stand and moved everything to the workbench but I still didn’t have a good system for variable speed. Well, no more cone pulleys, countershafts, or underpowered AC motors… I bought an old treadmill with a 1 HP DC motor and hooked it up.

The block of ipe you see on the lathe was the breaking point. The 1/3 HP motor would just turn it and once I laid tool to wood, everything would slow to a crawl. That prompted me to go find a proper motor. The new (to me) DC motor doesn’t even know the ipe is there, doesn’t care. It’s also scary fast for a lathe that was designed for treadles and jackshafts, gotta keep the power down.

I reused parts of the frame and original motor mount. It’s ugly but I’ll take care of that.

Basic box over the frame. Next I’ll enclose the motor and build a control panel.

Stay tuned!

Good luck. The days of free treadmills aplenty are long gone; or at least they are around here. Ten years ago you couldn’t give one away but now it’s hard enough to find one under $100.

Wow love the idea. Howdo you know the horse power of those motors and capacity of the variable drive?

HP rating and amperage is on the motor plate.
