What will you be using for bearings, plain bearing or ball or roller bearings. For plain bearings (bronze or brass) you only need to leave about .001".0015" for polish and check frequently as you polish. for ball or roller bearings you should have a + or - nothing would be good. A fit that you can push on with you hand but no slop.

It will be ball or roller it is for a wheel so what ever is best and fits. To polish would you just use sand paper and is this more for looks or function as far as the bearing surface or as you say just so it fits good?

Well it is for a half scale model of a world war two vehicle when done will weight about 450lbs. this is for the axle for the wheels trying to make as close to the full size part as i can finish ect.

Work your way down to 2000grit paper, and you will have a absolutly wonderful,chrome-like, super smooth finish, pretty too.

Front axle or rear? Shouldn't be a need to polish. If it's for the front, it doesn't really need to be tapered either. Just cut it down for the outer bearing and thread the end for a castle nut. (with cotter pin) The bearings should be a slip fit on the axle. The nut is used to preload the bearings (roller).

If the axle (wheel off) will be displayed, then rough taper between the bearings and polish with sandpaper. How about some "progress pics"!
