I did what Jerry Hossom told me to do, and it works great. I took a used 500 grit belt and worked it over till it was really worn out. Then I took a blade and started sanding. It came out like a mirror!Thanks Jerry!!! Take care! Michael

something else that works really good too are the 9 micron film backed belts from 3M, be careful on the edges with your fingers, they are like razor blades when you are slack belting.

You're right Tom, Microfilm belt edges are brutal. They cut deep and take forever to heal. The best thing about worn 400 and 500 grit belts though is the price.

I've heard so much good talk about the 3m micron belts I'm gonna have to get a couple and try them.
Jerry, would a worn out 600 grit belt be even better???? Take care! Michael

Does this work with very worn out 3M trizact P45 belts, too?

Have a nice day!

It does not work with Trizact belts, because when they wear out all the grit is gone. That's why they turn dark; you're looking at the backing. The worn grit on other belts still has some abrasive and cutting qualities, just much finer than that for which the belt was rated. My worn out 400's cut much like a Trizact 16, but require more pressure, even though I finish with lighter pressure just at the end. Trizacts work best with light pressure, and personally I think they're great belts.

i think you can use 400, 500, 600, or 800 grit belts when all the grit is gone for polishing...just make sure you keep them where nothing will get on the belt and cause a scratch...i have always found that the brown flex belts (aluminum oxide i think) lose their grit really fast and work good for polishing...however...the key to mirror polish is having a very thorough technique for getting each decending grit pattern taken off by the next grit...so you dont end up with deep scratches at the end...i thoroughly believe the most important steps are the 120 and 220 grit as this is where the deep scratches will disappear. 220 plenty. thats my opinion.

after telling you that...i should confess i havent mirror polished a blade in over 8 years.
 
I don't blame ya Tom. I think as soon as I get some 60 grit a/o sand for my blast cabinet, it's blaster city for my blades. Take care! Michael
