    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.

    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"

    I din't know that there's any definable advantage either way, it's more a personal preference. I have both fluorescent strip fixtures AND halogen flood lights as shop illumination. The sort-of...

    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...

    I may be out of touch, but $450 seems like relatively low cost to me, for a machine that seems well-kept and isn't covered in 19 years worth of mouse droppings and pigeon poop. Has the look of about...

    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...
