This is an email I got from Jerry
Hossom. I think he pegged my problem. Can't wait to get out to my shop and wear out a 500 grit belt.Thanks Jerry, big time!
Michael,
I get pretty darned close to a polish on a worn 400
grit belt. If Klingspor Gold belts were made in 600, I would use it. I
use them because they are very flexible and run smoothly. My guess is
your problem was the belt was just not worn enough. When Loveless said
"worn", he likely meant "really worn". Mine are really really worn, and
if they're not worn enough, I wear them more by using a wheel dressing
stone I got from Brownells. It is a bit like a chunk of cinder block
that will smooth out the grit on any belt. I often use it to break the
corners on rough belts when I start grinding, so the plunge is smoother.
I frequently find I need to use the stone on the edges of the 400 belt,
where they seem to wear less than in the center. At least on my wheel
they do.
I finish using a very soft touch with the 400 grit belt, then I
sometimes go to an 3M Apex 16 if it's a larger blade. The soft pressure
is key, and usually I can just go straight to a dark green compound on a
hard buff and be done in about a minute per side. I then touch up the
mirror with scratchless pink from K&G - 30 seconds maybe. Not quite
polished with the belt, but no scratches at all.
