Hi gang;
One of the things I'm considering for possible CNC conversion is the 9" X 20"
bench lathe from www.wttool.com. I'm wondering a little about the ability of
this lathe to do what I want to do, though. This would be making crankshafts
for small to middling size engines. The ad says it comes with a 3/4 HP, 60 Hz
motor, 6 speeds from 130 to 2000 RPM. It seems to me that 130 RPM is a bit high
for a large, out of ballance load, like an unifinished crankshaft, even if it's
been mostly milled out, prior to chucking up, and packing in the lathe. It
doesn't say what sort of drive this is, and I'm wondering about methods for
reducing speeds here. Can anyone tell by taking a look at the pic/specs whether
this might be suitable for whatever workable methods? A swing of 5 1/4" over
the cross slide at speed, is room for a lot of mechanical energy whipping
around.....
