This saw is clamped by a nut to thespindle, which runs in a long bearing bolted to the slidinghead. The bearing is removable and is cheaply replaced with the mica slots. This adjustment is of great impor-tance because the mica frequently does not run true withthe shaft.

The weightof the machine proper without the motor is 148 lb. Theweight of the rear support is 35 lb.
