I can relate to it, I just can't do it!

There used to be for sale a complete hardcopy version of the Shop Notes from 1905 to 1930, plus a full index in another volume. I don't know if this set is still available to buy, it's 26 volumes, and was a couple of hundred dollars(?) when I bought it several years ago. I have read and thumbed thro...

Jim, (or anybody): About the digital inside mike, can anybody explain how the presets P1 and P2 are used? Do they cause the mike to recalibrate itself somehow, or are they just used for doing relative measurements? I have misfiled the instruction sheet (read: it has disappeared into the chaos that i...

Thanks y'all. Some good recomendations there.

I have a house brand metric set from one of the big tool houses. They were crap.

I need to start getting some # and letter sizes of imperial twist drill bits.

What is a good brand of twist drill bits? Any makers particularly recommended or any to be avoided?
