The usual rule is 1 thou per inch of diameter.
That, or even slightly more, shouldnt crack cast iron.
I prefer shrink or press fits to glue, although some of the modern adhesives
are excellent.

Subject: [modeleng] Press Fits
Hi,
I was wondering if anyone can give me some idea with regard to press
fit
tolerances, I have to press fit a silver steel crank pin in to a cast iron
wheel. As far as I can tell the nominal hole size is 0.750 and is already
in
existence how much should I allow for a good press fit without running the
risk of cracking the cast Iron wheel. Or would I be better obtaining a
proprietary adhesive and using that. If so what would you recommend, I am
fitting
crank pins to the wheels.
Many thanks
Don.
