I have a 16" LeBlond lathe missing the entire thread chasing dial assembly. And unlike most lathes, this one doesn't have any mounting hole, just a shouldered hole for the thread chasing shaft. It looks as though the entire assembly rests, suspended by the dial itself. Anyways, I have a 6 tpi lead screw with what looks to be an 18 dp thread. When I measured where the gear would sit on the shaft, it measured 1.5". But doing the math it showed that I either have to use a 24 tooth gear which measures 1.380 which is too small to reach the lead screw threads or 30 tooth which is too large/wide to fit. Assuming the gear has to be divisible by 6? What am I measuring/doing wrong?
