Aha,

That's a way to do that I suppose. How do you support the blade disc in the press? No worries with distortion, buckling etc? Usually a bent blade disc is very obvious. Perhaps I could fit PTs or FCs to some of the many Rover bases I have or can get easily? I have plenty of good Rover catchers but have started to dump the bases. I can tell you nothing else works to solve that problem
I have tried everything.
