My reamers seem to be slightly undersized.
Thanks Marv. I do have a set. Rarely used.How does one know when to use an undersized or oversized reamer?I can see how an oversize might be used after a nominal (or undersized) but you'd have to start with an undersized.I suspect part of the answer is more accurate (and expensive) measuring tools.
Thanks Bill. Press fits hadn't occurred to me.Yes Pete. I have a "decent" 1" micrometer. I got it many years ago for measuring electronic component leads.Good to know that different materials can give different results. That may explain a few things I've noticed.I'm not sure I understand a 10th under/over. +/-0.1 ? That seems awfully big.
I can't believe it! I left out the crosshead guide! Argh.
