Re: Press Fit
A standard Type II color anodize should not add any more than about 0.0004 inches. A hard anodize certainly would. I second the recommendation to capture the bearings, and size them for a close slip fit. Pressing them is nice simply so they don't fall out during maintenance but it's difficult to get the perfect fit. You're looking for in the neighborhood of 0.0003 smaller.
Unless you have a high-end shop doing the work to your tolerances and inspecting it, be sure to give them an actual bearing they can reference to check as they're machining the parts.
