View Full Version : Change gear identification

06-28-2009, 01:08 PM
I have a set of change gears I am trying to verify are possibly for the Logan or Atlas lathes. I have a South Bend with a quick change and know they are not for it. I am guessing these would be for a lathe somewhere in the 9-11" range but I could be wrong.

The gears are 16 DP; 7/16 (.440) thick; 5/8 bore (0.625); 5/32 keyway (0.157); they have 4 holes through the webbing from 44 tooth on; all are cast iron.

I received conflicting information that the change gears for Atlas were 3/4 bore.

Any insight would be appreciated.

Atlas gears are made of Zamak and look kind of like aluminun. Any other brand will be castiron.
