Hello, All.

This is a follow-up to an earlier post I probably placed on the wrong forum. (Thanks for the good info and guidance I received from all who responded.)

Now, on to the next iteration in revitalizing a nice old machine:

I have recently acquired a very nice Kin Shin lathe built in 1976 - Model KS3.5FK. While the machine is very tight, it is not running because the motor is not wired to it. I doubt it is the original motor, and I'm not confident it is right for this machine. It is a Westinghouse 1/2HP 110/220V 3450 RPM single phase. It's my understanding, however, these type lathes were typically geared to run at 1725 RPMs on a 3/4 - 1 HP motor.

Anyone out there with experience on these older Taiwan lathes that might know more specifics on original motor configuration? I've done a little research and found that this machine appears to be identical to a Jet model 1024.

Thanks in advance,
Terry

Terry,

I'm familiar with the older Jet 12 x 36 bench lathe they built in the late 1970's into the late 1980's. The motor was something like a 1 Kw or 1.5 HP. And it was 1725 RPM. I don't recall any of the jet lathes having a 3450 RPM motor on them. The one I dealt with, the wiring had to be completely redone for the new motor. The electrician we had just installed a typical light switch as you would use in your house! Still being used when I left there. Ken

Thanks, Ken.
That confirms exactly what I anticipated. Wired the Westinghouse on the workbench yesterday. Good news: it works; bad news: thought it was going to levitate. 3450 RPMs is way too fast for this machine.
Don't understand all the ins-and-outs yet of hobby-machinist, but somehow I managed to have a 'conversation' with someone who posted an excellent thread on restoring an old Jet. He still has the old motor and will send a photo of the specs later today. For informational purposes, I will add that to this thread ASAP.
Thanks again,
Terry
