Put the compound parallel to the main bed way. Engage the threading gears, and turn the lathe over by hand until the carriage starts to move. Bring the threading tool toward the existing thread using the cross feed until it is close to the major diameter, then adjust the compound until the point is centered in the thread. Advance the cross feed a bit, and adjust until the tool is all the way down into the thread. This will allow you to pick up and continue the thread with minimal error.
I have a 1.0 in. round with 1.0 inch of threads. Is it possible to chuck this round up and extend the threads to 2.0 inches? Can I set up for the 13 threads per inch and engage the carriage feed and slip the round in the chuck so the bit is in the first thread groove? Or is there a better way?
