| thread dial for a minilathe. |

| wheeltapper:
Hi I have a small import lathe, it's a Chester Comet, its metric and I would like to make a thread dial for it. the leadscrew is 2mm pitch. what I need to know is what diameter gear and how many teeth do I need to mesh with the leadscrew. thanks in advance for any input. cheers Roy. |

Hi Roy -- My 2mm pitch leadscrew is (Maj Dia) 15.95 mm and uses a 16T gear to drive the threading dial. Does this help? |
| wheeltapper:
Hi thanks Lew, that gives me a start. I've been trawling the net and the more I read the more complicated it seems. some say you need two different gears to cover the range. lots to think about. cheers Roy. |
