I bought a "railroad" grinder off of ebay to grind my chisels and plane
irons. Its super heavy and very well made. I opened it up to check the
gears and grease them. I was not prepared for the weight of the outer
casing
when I pulled it off and dropped it on the concrete floor - you guessed
it.
It broke off the most critical part of the casting - the part where the
shaft for the grinding wheel goes through. Its only one half. The other
half
is intact.

I was wondering if there is some form of epoxy that could be used to
repair
the casting. I don't think I'll have much luck chasing down a welding
shop
for this small job. Since its hand held and there is not much heat
generated, I don't think it will take a lot of strength to hold it
together.
