Ditto! Already worn out the first one and well on the way with the 2nd one. We use them a lot at our place.
I just use a regular sanding disc flipped over so you're rubbing on the fiber side, works pretty well, and a whole lot cheaper since I get used ones at work that they are throwing out. Dan
John K has some nice videos on youtube too. I have used a fiber grinding disc once it had been worn too far to sand.. it just caused friction. But that friction worked well to make me believe that even I could use a proper disc like like John sells
Wray Schelin or John Kelly - both have DVD's available too showing their use (although it's a pretty simple tool, theres some really useful finer details that are good to know) Guys in Europe can get from Ben van Berlo: http://www.bensmetalshapingshop.nl/ He has them for 4.5" grinders - great for smaller areas.

Doesn't have to be flat (or stainless for that matter- mild steel will work too, just more prone to galling) John Kelly has a crowned disc which I believe is very useful for flat panels. If you're seriouslygonna try a pot lid make real sure it's attached well and inspect regularly - all the pot lids I've seen are 22 gauge or thinner. Shrinking discs I have from Wray & Ben are 16 gauge (at least). My first one from Wray cracked on the edge due to incorrect technique (running on the edge too much instead of entire face)
I have stopped making shrinking discs. My tooling is worn out and I am tired of making them. I highly recommend the one from Wray Schelin. He is the innovative metalshaper that gave me the idea to make the first flat disc on the market, not a copy cat rip-off like so many others. John www.ghiaspecialties.com
