Of course, it left the lathe still lacking in many ways (especially the "ways", LOL).
I mounted a permanent magnet DC motor on my mill drill and found that it lost torque the slower it ran, so I still had to change belts to get the "Oomph" required for slower spindle speed work.
I'm presently (read eventually) going to replace my self installed single phase motor on my Tree 2 UVR mill with it's original 3 phase motor and drive it with a VFD. I'm curious to see what the lower speed torque characteristics will be.
Thanks, stevec. I have an Atlas of my own so I know what you mean.
I figured it would lose some torque at slow speeds so I would plan to include as many steps as possible with the space available. That way I could change out the motor easily if it isn't working satisfactorily.
Thanks, Mayhem and EdK. I'll be sure to post pictures as I go. I'm looking forward to learning some new skills along the way.
