Correct but your engineer that is doing the rebore should know all this.
Edit, just to clarify, I am responding to your drawing above, where you are showing 0.0254mm piston to bore clearance. But I must reiterate, your engineer should know all these measurements and what they mean.
Bryanj:
Julie is right, they SHOULD know thatthe clearance is 1thou but a lot f old school engineers insist that is too tight and will sieze. If they try and tell you that go elsewhereuntill you find one who will do it right or you will burn oil.
murdock:
I doubt that the machinist of the places where I can go are even engineers, so I insist on the measurement in millimeters, since the imperial measurement is not handled in Spain except for plumbing,
If I have that measure, I will insist on that, and if something happens it should be under my responsibility and not that of the machinist

I feel that we are confusing murdock with our imperial measurements - just to clarify murdock that for your country you should concentrate on the 0.0254mm (which is not 0.25mm unless) measurement
