3mm Apex seals:
As to modifying the rotors for the 3mm seals why not use a wire EDM to

make the

new slots? No one has posted the tolerances yet, but I can hold a tenth

with some

care in the lab, and I'm just a senior engineering student. If you work

at it

millionths are doable. Some of the electrical parameters can be jiggled

to leave a

very fine surface finish.

Are they currently ground out?

Yes. Hurley grinds them.

EDM is something like Electron Displacement Machining.
