Rather than inline the carriage drive screw, with will leave the motor hanging out quite a ways on the left end of this lathe, I could save about 3" if I mounted the motor to the bed on another piece of 1/4" alu plate, such that a gear on the motor shaft would engage a gear on the lead screw.
I bought a set of steel change gears before I got the bug to put motors on this thing, so it looks as if I can drive a 65T on the lead screw with a 35T on the motor, an 8 wire 425 that says 5 amps on it, but I suspect that is a per coil, one at a time rating. I am only using about 2.40 amps on the Z axis for the mill and it certainly seems to be enough when the coils are wired in series. I can put 155 lbs on a bath scale with it, which is a heck of an improvement over that same motor driving the old, back of the post screw and tapping the motor out at 5 lbs showing on the same scale. Anyway, is there such a 'hub' I can buy, or am I doomed to try & make it? Thanks guys. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
