>>HISTORY<<
Aug 2009: BOYD trade with fellow OWWMer.

Feb 2010: Disassembled. Used split bearing puller to remove inner flanges.
Shaft removal: http://www.owwm.org/viewtopic.php?f=1&t=70095&p=491851

Mar 2010: Washed parts in Zep Purple cleaner and wire wheeled rusted items.
Spot-faced shaft in two places for pulley set screws.

Apr 2010: Painted castings. Primer-Krylon gray. Two top coats-Krylon Oxford Blue Satin.

May 2010: Machined .002" from LH shaft bearing surface to allow slip fit.
(This will allow the grinder to be easily disassembled for belt installation.)
Replaced thin guard and tool rest washers.
Craftsman logo tag--tapped body for 4-40 machine screws at drive screw locations.

Jun 2010: Test run.
Companion 115.5454 1/3hp 1750rpm motor, cone pulley using 2¾" & 3½" grooves,
Craftsman 2730 floating motor mount, Craftsman 2140 16x18 steel frame stand.
The grinder runs around 3500 & 1900rpm.
I'll use the RH side (with guard) for grinding and the LH for buff or wire wheels.
The LH tool rest tucks out of the way by mounting backward in the guard attachment hole.
