I'm looking to put together a set of ball bearings between about 4/16 and 1", in as small increments as possible for removing dents from brass instrument tubing from the inside. What size increments do readily available - i.e. "off the shelf" ball bearings normally come in?
One supplier has said in that size range they have 16 bearings - 1/4,9/32, 5/16, 3/8, 7/16, 15/32, 1/2, 9/16, 19/32, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1 inch. I see there are several gaps where the size jumps by more than a 1/32. I was hoping to find a set that more evenly covers the sizes. Is this a realistic goal? I'd like to find them all at once instead of piecemeal it together so it would be worth the time/bother for whoever sends them to me.
Would I be more likely to find a greater number of increments in metric or inch sizes? In fact, if I included both metric and inch sizes, would that be likely to fill in "gaps" in sizes?
Thanks for all input.
