« Part 3: Motorin' - or How to wire a 3 speed AC motor. Part 4 of Goodell Pratt 125 Bench Lathe series Part 5: Pulley glue-up and guess the wood. »

Credit where it’s due, I basically copied this guy’s stand except I modified the top to work with my lathe.

I had literally a wheelbarrow load of scrap fir 2×4’s from another project so I used as many as I could. (Note: never build anything from fir 2×4’s, the wood is soft and brittle, every little bump is a dent and pieces kept flaking off at the slightest provocation.)

Sorry, I have no in-progress pics. Once I get started I don’t like to stop for pictures but you can watch the guy above build his. The joinery are simple half laps. The top is 3/4 birch ply with 5/8 pine ply underneath and it press fit between the aprons (later screwed in). There is also a simple box mounted under the top and between aprons to help support the motor mount. My casters are cheap plastic because I had them.

Next up was the motor cradle and mount. The cradle is built from 3/4” birch ply. I took the half moon cut outs and trimmed a couple inches off the flat side, turned the two mini-moon shapes with the curve pointing down and glued them between the cradle sides then added a bottom. The two small pieces are to hold the band clamps. Since I didn’t take any good pics of this I’ll add a crude drawing.

The motor mount was then attached to the apron with an old Stanley brass hinge.

And that’s where I am today. You might notice the v-belt is touching the lathe which is not good and I may have to move the motor mount higher. I’ll be using a flat belt to drive the motor and I’m hoping it will clear.

Next edition will be turning the driver step pulley from ipe.

Been watching your progress on this. I’m wondering how the 3-speed motor will perform, not just “speed-wise” but will it be strong enough as it only pushed a fan blade in it’s previous life.
And do the casters lock so the lathe wont walk away from you while your putting tool pressure on it?

The casters do lock. Once I clear some stuff out of the shop it’ll have a permanent place and I might replace the casters with wood feet.

I just noticed something else. Once it’s up and running, based on the direction of turning, you’re gonna be throwing a ton of chips and DUST at the motor. I wonder if you might be able to either
A: Put a tin sheld on top of the motor to deflect the debris away, or
B: use some very fine mesh (like window screen) to keep that motor from sucking in all that dust.

Just brainstroming on your project here… :-)

Looks good so far

Good point. I hope to eventually construct some kind of dust collection but in the short term I might make a shroud out of cardboard that will funnel into a bucket.

Also, forgot about the motor power question, really there is no way to know until I try it. I tested the lathe on a 1/3 HP motor and had zero issues.
