I replaced the flat belt pulleys with V belt pulleys on my first lathe (an old Atlas flatbed) and found the performance greatly improved.
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.
