Hey Gang - Kind of a weird question:
I have an old, old print with a thru hole callout for "REAM .501"
The obvious thing to do is run a .501 reamer through it, but I don't like reamers, and my mill has very limited Z travel, so reamers don't really like me either. I would much prefer to interpolate the hole...but to what size? I know it's not all that hard to get under or over sized holes with a reamer (which is one of the reasons I don't like them) but also what would a fair tolerance range be? Even if I did want to use a reamer, who's to say it would match the original reamer they had when the print was made some 60 years ago?
I know there are a lot of unknowns, but I'm just looking for a rule of thumb or best practice expectation for results with a reamer that I can duplicate on a print with an actual tolerance.
And no, asking the customer isn't an option (long, weird story) and I don't have the mating details, and can't get them.
Thanks All!
Edit after a couple of replys: Maybe a better question is: If I buy a .501 reamer and follow the manufactures recommendations for SFM and amount of material left to remove, what's a fair tolerance to expect? Is the .501 +/-.0002" reasonable?
