Yes! Another fine article from Rick
I own one of these grinders and it sure is a work in
progress. The only source for aluminum oxide wheels
that I was able to find was from Wholesale tool
<http://www.wttool.com/index/page/product/product_id/489/category_id/13473>
It took three tries to get a wheel that was somewhat
acceptable. But Wholesale Tool was very gracious
about getting me a wheel that didn't wobble too bad.
A diamond wheel for this grinder was probably a waste
of money. It doesn't remove much metal and is only
good for final grind or polish.
On a slightly related note, a Work Sharp 3000 found
it way to my shop. One of the wheels is a leather
hone. So the leather will better accept the honing
compound, a packet of White Petrolatum USP is included.
A chat this afternoon with my friendly pharmacist
informs me this is simply petroleum jelly.
Who would have thunk it?
