Around half a thou (.0005") is pretty standard in FRC. I suggest getting a 1.1245 (or 1.124) and .8745 (or .874) reamers to do the final finish.

Here is an old thread to reference: http://www.chiefdelphi.com/forums/ar...p/t-98825.html

I don't mean to change the subject, but this information has highlighted a problem for me. I've been designing a gearbox for quite some time, and I've clearly been making a huge mistake with the hole sizes for the bearings I'm using. If an AndyMark flange bearing has an outer diameter is 1 inch, in accordance with this, the hole diameter for the bearing should be 1.0005 in? That seems really close. Could you just verify before I go back and change everything? Thanks
