Re: press fitting
An arbor press is good, a hydraulic press is better. A bench vise will also work in a pinch, if you can extend the handle enough (put a steel tube around the handle or something). A hammer and punch will work for dowels, and instead of using a piece of pine between a bearing and a regular hammer you can use a deadblow soft-faced hammer.
A standard tolerance I use as far as making the holes for bronze bushings/bearings and dowels is diameter +0.000"/-.0005", by reamer. If no reamer is available... uh... an equal size or slightly undersize drill bit *may* work (1/64" under).
