Or can I just hog away? I got some of those reamers from Schaff years ago and they're all oversize owing to the rust that's grown on them. All they are is a modern version of the old spoon bit or quill bit. They're good for eating hummimgbird eggs with. If I were you, unless the 3/0s are impossibly tight already, I'd just bang in the new pins and if they're too tight screw them out and bang them in again until they're not. If the 3/0s are chattering, clean up the hole first with some P.120 frecut paper and put powdered resin (or fiddle rosin) on the new pins.
