Craftsman Commercial bench grinder, model 397.1949, 7" x 1" face x ½" arbor, built by Delco.
1/2hp, 3580 idle rpm, Design# C3083M2, 5.2/2.6A, 115/230V dual voltage, extended length arbor shaft ends, die cast aluminum body.
Missing: quench tray, OEM lamp, exhaust style guards, 2-piece tool rests, spark guards, eye shields.

I picked this grinder up at a garage sale for very little money in the mid-1990s.
The original owner stated that it never ran correctly.
It had a terrible vibration at full speed.
I disassembled it and found one of four armature to end bell screws not seated properly.
It runs perfectly now.

I added a flexible lamp assembled from stray parts.
I wired the lamp to to a flat blade connector, attached to the on/off switch.
The on/off switch has two 115V connections. One always live with the plug and the other when the grinder is powered on.

Since original guards are nearly impossible to find at a reasonable price, I've dedicated this grinder to buffing and wire wheels.
Presently, it is mounted to a newer Craftsman imported cast iron and steel stand.

ArnFest 2006 attendees might remember using this machine during the Delta shaper restoration.
