Did you have to make up a special pilot to align the cutter to properly cut the seat? Is a suitable one available?
Russ,
I used this pilot with a Neway cutter when renewing my Black Shadow valve seats.

I also enlarged the hole in an extra upper valve guide to .375" and inserted it while cutting each seat, to help align the pilot correctly.
