>1-1/2x8tpi. I have a TH42... the 1" spindles are on their 6" lathes... can, IIRC, be 1x8tpi or 1x10tpi depending on age.?
?
All of the Atlas badge 6" lathes had 1"x10 tpi. The early Craftsman badged ones had 1"x 8 tpi and the later ones switched to 1"x10 tpi.?
As far as I know nobody has ever confirmed why Craftsman wanted Atlas to make the 1"x 8 spindle but most speculate it was so chuck threads matched their wood lathe spindles at the time.
