Hello,
I'm trying to resurface the magnetic chuck on my surface grinder but
the grinding wheel I have is too hard to do the job properly without
clogging and bouncing before I'm even a third through. It's a mess and
iirc the job calls for a soft, open grain wheel, no?
Wheel is 7" maximum and I could use specifics on grain, bond, etc for
all around general purpose use.
A link to a simple tutorial and if possible Graingers or MSC stock #'s
would be appreciated.
Cordially,
Al


Al, you want a nice new White wheel, about an 80 to 120 grit.

Take a Magic Marker, and swizzle it around the top of the chuck. Dress
the wheel square, and take cuts of no more than a couple tenths per
full pass. When the magic marker is completly gone, repeat once more,
with magic marker, make another couple tenths pass, , then its time
to stop. Holes, gouges and pits will harm nothing. All you want to do
is make sure its flat to the wheel travel, with no raised edges around
the craters. If you have coolant..use it.
