This week I actually Got a new Box of wafers from Hollister and a couple of barrier rings. Now, what the hell to do with the rings. I think I remember people saying they can use the rings on either side of the wafer. The hole in the wafer is 3/4 and my wafers are 1 1/8. I think I can get away with +_ 1''. I really could use some input on how best to use these rings. Thanks. Ed
