CC per 0.001"

[D-1]

Does the 0.007" per 1cc (approx) on TC heads work for 110 or MVA heads too. I need to go from 94 to 91.

It will take a few hops. Start at -.015.

Thanks

We consistantly see .006" per cc.

Took 0.017 off and got 90.8cc, so thats just under 0.006" per 1cc as said above. Thanks for the guidance.

In your case .0053"/CC, and that is not a static number. The chamber does not come down in a linear way as you move up with the amount milled. As stated by others in the past and for the benefit of others in the future, it is best to creep up on the number and not rely on a certain static CC/in figure except for the roughing cut.
