Need some help from my head machining buddies
As mentioned earlier you can't take big cuts with it. You'll have to toggle between 3 angle seat cutter and 75° bowl cutter when increasing valve size. The more angles you try to cut in one shot will cause more deflection. I have used a DCM, Sunnen VG20, and a Kwik Way Head Shop. The Kwik Way looks similar to the Peterson. It is not a ridgid machine, but can do good work once you learn the quirks.
