I just measured the interference fit of the 6004 bearings used for the X axis leadscrew.

42mm = 1.65354", and I measured ~1.6535"
I measured the bore as 1.6513" using a telescoping gauge, not sure how accurate my measurement is?

So the interference appears to be about 0.002", when I pressed this out using my vise, I would say it came out without a lot of effort, definite pressure but I have pressed out much tighter bearings.

Does that seem about right or is my bore measurement a bit on the light side?
