I purchased a Taig lathe and want to set it up.
I have a 1/3 hp 1725 rpm motor, but I like the idea of variable speed.
The Sherline unit is too expensive, so I thought of adapting a 4 amp,
3/8 variable speed ( o - 2500 rpm ) drill to turn it.
Would this drill ( better cooling, 90 wt. gear oil in reduction drive
and bearing lubrication ) work well enough,time to failure, wise, or is
this a poor idea?
It might be OK in the short term, depending on what your work is. I
suspect it will be a poor speed/power match. And most drills are
intermittent duty. Might not live very long.
Taig sells a step pulley set that uses a very thin belt
that has worked great for me. I have the motor mounted on a hinge and lift
it to change speeds. Very quick and easy. Why not use a DC motor and speed
control or some type of universal motor with a router speed controller?
Hint: of these two choices, DC is much quieter! Universal motor-think
vacuum cleaner or router.
Harbor freight sells a 12 VDC pump that has a lot of torque and is on sale
for about $25. I think it would be a good match and easy to adapt.
Or just pick up a junk treadmill and scavenge the motor and controller.
