It takes me all of about 2 minutes with 1/4" drill because I have a Norton seeded gel wheel on the bench grinder. It's been on there for over two years now and I haven't ever had to dress the wheel. It still looks new even after some pretty heavy grinding. I'd picked up a couple of them for $5 at the annual Norton Company "yard sale" they run as a United Way fundraiser.

Far faster than any belt grinder! The 3x36" Norton zirconium coated belt on my dad's belt sander is all clogged up with wood anyhow. ;)

Ken,

What the heck is "a Norton seeded gel wheel"? 17428
