Archie, can you grind apex seal slots to 3.5 mm? Shipping 18 pounds
back and fourth to England gets expensive and I can only take a
limited number of rotors in my check on luggage. Not to mention
explaining to US customs what they are when I come back in.

I have not tried it, but seems straightforward.
Standard vertical surface grinder should handle it.
Need to fabricate a support/ index fixture, &
generate a grinding wheel.
Why would no one do it locally?

I have not looked for someone to do it yet. The grinding improves the surface finish
which apparently cuts down on the leakage at low RPM. Might be a good
business for you Archie. I would rather deal with someone doing it on a
regular basis.
