I am ready to make a mechanical drawing but have issues

[Hyperthread]

One question is, I need a rod that both has grooved bearing tightly fit and a linear bearing on the same rod with no slop. Is this possible? What is a "press fit" tolerance? If I have a 0.5 hole, what size rod will be press fit? What size will locate without pressing? Boy I wish I had an engineering friend that I trusted. Thank-you.

Not used it myself but Google found..

It defines various types of "fit" eg sliding, interference, force etc. Also has calculators for working out the tolerance.
