Excellent! Yes, I'm on my third quarter-sheet sander dedicated to finishing flat ground blades. I'd never do it any other way anymore. But I never thought of backing the Micarta with cork - I think I like that idea. Where does one find this stuff? Auto store or somewhere? I've never used adhesive to attach the paper, just the clips that originally held the paper in place. Doesn't the adhesive pull the cork away? And doesn't the spray adhesive build up on the cork? I use acetone to clean the adhesive from my disc grinder; would the cork surface hold up to that? I like the idea of the cork surface, just wondering how well it will work.
I have not read all of the comments, so I apologize if these questions have been addressed. Either way, I've learned something valuable again today, and I'm going to see if I can find the cork stuff and give that a try immediately. Thanks Ed!
But I really would appreciate it if anyone could fill me in on where to find this stuff. We've just had a pretty good snowfall and I'd prefer not driving all over looking for cork!

Curious about the adhesive question too. Thanks for any help. Have a great day all.
