Hello, All.
This is my first post with a call for help on belts and pulleys.
I struggled for years making a Chinese mini-lathe meet my needs and finally 1 month ago acquired a 1956 9A. The significant event here is a conversion to a 3 phase Baldor and KBMA VFD. The 45 lb. countershaft is gone. I have made a motor mount from 3/16" steel plate that is sandwiched between the left base and the ways. Photos to follow.
Because sellers want a fortune for the V-belt cone spindle pulleys, I am forced to try and make a flat serpentine belt work. And BTW, I am targeting a 1:2 or 1:1.5 reduction ratio on the 1750 rpm motor, using the largest rightmost flat spindle pulley.
So, if I had a second lathe, I would make a 2" in diameter crowned pulley, 5/8" bore with 3/16" keyway, but I don't. Every thing is available on the internet but this.
Any advise on this pressing matter?
