Hi to all, has anyone ever considered ball-milling out the apex seal grooves and pressing in a round tough steel insert and then milling the seal slot in the steel insert. This would then be' horse shoe' cross section, so to speak. The corner button seals could also fit into the ends. Maybe a new rotor would be cheaper, but this may have better reliability and longer life. FWIW, Dave Mc

Sounds expensive. And how will you keep the insert from flying out of the rotor as centripetal force tries to fling it out at 2000RPM?
****Hi Ernest, I think you mean centrifugal force;
Don't you hate it when you out-think yourself? (Repeat to self: centrifugal force, centripetal acceleration...)
and if the slot was ball-milled, the insert would be captured by both "claws" of the milled channel;
The root of the problem is that the rotors are ductile iron, a rather soft substance (soft being extremely relative here). The "claws" would have to be very thin and would give way rather quickly.
also, just like the seals, the rotor housing would contain the whole assembly. Anyway, I think your comments about 400hrs/ 5 years makes much more sense in the overall scheme of things. BR,Dave McC
Phew! Glad I'm not completely daft today!!
HEH! I just won an eBay auction for a Mustang throttle body!

decisions, but in doing so we actually hurt them (and ourselves)."
