    This sounds like one of (3) possibilities:
    1. An add-on or optional package that you could buy with a CMM or some other sort of automated inspection system,

    RE: the phenolic material -- As was previously noted, paper-based material will be the most uniform in appearance after machining, and a good-quality XXX grade will be the best in that regard. This...

    Just a side note: You may want to check that sine bar with a Geiger counter, in case it actually got used for setups in machining the facets on U-235 or plutonium sphere segments. That work may have...

    You have gotten good advice above. Keep in mind a couple of things:
    1. A 3-jaw chuck is a convenience tool, and not designed for highest precision. I purchased a new (old stock) 3-jaw chuck about...

    Powermatic model 66 saw serial numbers

    I went to look at a Powermatic 10" table saw for sale, which seems to be a model 66. I am not that familiar with Powermatic machines (I have a Unisaw), but I was hoping to be able to figure out the...

    It has been a mystery forever to me why this happens sometimes and not others, and always seems resistant to rational analysis and solution. I often use a backing plate in doing small...

    Too bad for Mr. Crotalus Atrox. We have a fair number of rattlers every year, but the local fire guys come and take them away, and allegedly relocate them. Probably to someone's yard 3 houses away,...

    Just beautiful. The combination of the woodwork styling with the "jet-age" leg connectors makes me think of something you would have seen in the movie "Dune" (the original one). I like it a lot.

    If you are holding the stock in a chuck, with some number of jaws, the closer the stock is to the chuck jaws, the more the stock is compressed. The workpiece will absolutely expand when parted off...

    The combination of both the wave/surf pool and the wave generator sounds like the beginnings of a really wet perpetual motion setup. You might suggest the additions to both parties as a way of...

    The real question is why do you need to find a tap for this particular bolt?

    You state "Bolt measures .55 (13.97mm)"
    Then you say "External thread measures 13.462mm (.535in). Pitch is 1.5mm"

    just to dot the "i" -- "Low Voltage" connection should be for 115V use. I suspect motor damage might occur if motor is hooked up to 220V while being wired as "Low Voltage".

    I have done this a couple of times for "crude" metrology, but it isn't high-precision. Much depends on how you produce the turned screw head. This needs to be done in a setup that allows the screw to...

    That's a good question. I may be conflating the symptom (over-heating) with the actual mechanism of work-hardening. Keeping the temperature down of both the material and the cutting tool does help...
