I use an old CPU Power supply on the 5 volt rail. It's about 4.8 volts at the motor.
The speed of the motor (via input voltage) also affects the way it will cut. Too slow or too fast and you won't get a nice finish.
BTW, most lathes with slave motors are wired backwards, make sure you check which way it is running or you will kill the bit in a second!
Thank you so much for that.
I have had a lathe before but forgot about the motor direction.
You Jolted my memmory now.
As for the source i was going to run a 4 cell pack but some companies put a high wind motor in for that reason.
Thanks again.
Mark.
