>>HISTORY<<
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.

Approximately 2010: Removed the lamp, and added steel tube spacers to move the wheels outward.
