9" Workshop Lathe
Back-Geared Headstock on all Models
All Workshop headstocks have quiet running machine-cut semi steel back gears and balanced three step cone pulley to assure smooth operation at all spindle speeds.   A quick acting wrenchless bull gear lock permits engaging or disengaging the back gears without using a wrench.
Heat-Treated Alloy Steel Spindle

The headstock spindle is made of alloy steel with carburized, hardened, and ground bearing surfaces with a hardness of 51 to 56 on Rockwell C scale.  All "Workshop" Twelve-Speed and Tool Room Lathes are equipped with superfinished spindle as regular equipment.  On other models, the spindle could be superfinished to order at extra cost.

The spindle runs in integral cast iron bearings that are equipped with an improved capillary oiling system and are adjustable for wear.  A ball thrust bearing and threaded take-up nut eliminate play.
