Monty,
I wouldn't take the = chance with a=20 RX8 apex seal going over any sized hole. Their not designed to do that = as they=20 are much smaller in height and IMHO they will flex and spit = out of the=20 hole. Deeper 2mm slots have been tried, with RX7 two piece but even = with a=20 wire cutter there is a small ridge left, which might hang up an apex = seal - so=20 I'm going for a 3mm apex seal.
The slot depth is = 9.8mm and is=20 just as easily cut with a fly cutter as a wire cutter.

George,
 
So I take it there is enough meat in = the Renesis=20 rotor to make the slot deeper? Somewhere I came across somebody stating = that=20 they were too shallow.
 
Yes 3mm seals are something I have = considered=20 also.
 
Of course I hesitate to cut into a = perfectly good=20 $500 part, but now I have a junk rotor to make sure. I also have 6 tries = to get=20 the setup right before the good part goes in the mill. ;-)
