    We used Rohm chucks on the drill presses in our mill maintenance shop . Chuck keys in a shop ? they don't have feet, they have wings. I caught a video where they explained how keyless chuck work.. They work on the camming principle . So they will spring the case and jam. Of course they got...

    I thought I might luck out and find it in the MH Collector's first edition, no luck. It's an obsolete thread from the late 19th century. I have an old Starrett thread guage and it had 22tpi where as the newer PEG ones didn't.

    Hello!

    The Aussies have drive thru's too. At least I saw them in the Northern Territories. I guess it was when they were buying by the carton, they could put it in truck of the car. I would think they would call it a boot.

    It wasn't the only handbook. American Machinsts' Handbook written by Calvin & Stanley and published by McGraw Hill was another one. Mine is the 1940 7th edition. It was recommended for shaper lore.
