>>HISTORY<<
I obtained this surplus grinder from the Sibley Machine & Foundry in April 2011.
It was used in their machining area for sharpening lathe tools and general work.

>>MACHINE<<
Black & Decker model 74 Type G bench grinder, built by Van Dorn.
8" x 7/8" face x 5/8" arbor
3/4hp, 3000/3600rpm, 10/9.75A, 50/60cy, added eyeshields.
Missing original tool rests.

UPDATE-15May2011: obtained a set of tool rests from a later model 74.

UPDATE-April2012: basically completed.
Found a NOS B&D A60 8" x 7/8" face wheel (right side) originally supplied on this grinder.
I still need to paint the tool rests and fabricate spark shields.
Used wing nuts on end shield attachments.
The eye shields (not OEM) were pretty mangled, so I'm leaving them off (I use goggles).
Original bearings were equipped with removeable shields and felt seals. Flushed and repacked with Mobil Polyrex EM.
New power cord and plug.
Retapped the two mounting holes to ¼-20 in the bottom of the base (original threads damaged).
When I get some time, I will fabricate OEM style spark guards.

UPDATE-July2015: Mounted to garage workbench and put into service.
