how do you thead with change gears?

I just bought a model c. I noticed that there are no dials for cutting threads. How do I know when to engage the feed?

You just put on the gears you need for the thread you want to cut and engage the half nut lever, make you cut and stop the lathe motor. The half nut handle stays up (engaged), back the bit out of the groove with the cross slide, reverse the motor and go back to the start point. Put the bit back to the start depth and move the compound in a few thou and take another cut. The cross slide will always be at zero for a starting point and just start and stop and forward and reverse your lathe. Just remember to leave the half nut lever up. Look in my SB 10K group i have a set up in pics that describes the whole ordeal, but its an internal thread. You will get the idea. ps THE LATHE WILL BE RUNNING IN BACK GEAR SO THE PROCESS GOES SLOW...Bob

Another approach would be to simply put a
thread dial on the machine.

Just because it has loose change gears, that
doesn't mean you are restricted to leaving
the halfnuts closed all the time.

Rodger what Bob said is an easy way of threading, but if you are looking for a thread dial I have one that I will sell. Joe.
