I have an 11/16 big hole mandrel which makes a fun ring in size 7 to 7 1/2, but the next size available (via Frantz) was the 3/4, which is 9 to 9 1/2 ring size. I've tried to double coat the bh 11/16, but the second coating of bead release explodes off. Ideas anyone? I've got a customer who'd like a size 8
thanks, Deb
