I've got a part I want to press-fit/force fit. I am going by ANSI B4.1-1967, with a fit class FN2. My shaft is 304 SS, and my hole is in 6061-T6.
The dimension I'm coming up with on my shaft is 0.1942" (+0.0003 -0.0000), and the dimension on my hole is .1935" (+0.0005 -0.0000). They're both lathed parts, and the interference fit is 0.25" long.
This seems... expensive. Someone tell me it isn't too bad or I'm doing something wrong/stupid?
