the 8" flat on this page is what boss was talking about, they have an 1/8" layer of rubber over the aluminum. http://www.therockshed.com/equipment20.html or https://www.kingsleynorth.com/skshop/product.php?id=97375&catID=1055
I think Nathan said his wife would divorce him if he ever made the discs again. I guess it was a major PITA. I know people that have them and love them though. I have the 1° disc that Tracy sells and I like. The rubber backing is a must, as is the feathering adhesive. I have a 1hp (1700 rpm) with a KBAC24 VFD. I rarely run it over 30%. I spritz the disc with Windex to help keep the paper from clogging and to keep it cool. It makes a mess on me, but works great.
