    The biggest thing is to make sure the wires go in straight. Kinks or
    twists will make life miserable later. I've seen people pull Romex
    off the center of the roll, without unrolling it. It makes a mess;
    bad enough when pulling through rafters but it's a disaster in

    You should. Obviously.
    It doesn't matter what *YOU* have on hand. #12 works just fine and is
    about 1/3 the cost of #10.
    Almost *NEVER*. In this case, it's *STUPID* to even suggest it.
    Wrong. There is no corners cut at all. You're lying, just to make
    some sort of point. You're wrong. Step up to it.
    What *YOU* did *100 YEARS* ago is irrelevant.

    Actually, that's what I plan to do. Put the compressor in the garage
    and pipe the air downstairs. 4" oughtta do it. ;-)

    I just have to figure out how much work it's going to be (how things
    line up).

    Where does it say I can't twist them as I feed them?

    You're the one inventing "machine shops" out of thin air. Go figure.

    #12 is normal stuff, sold by the pallet at HD. #10 is "special" and
    quite expensive because of it. Anything outside the norm has a
    premium attached to it. For example, 12-3 has only 33% more copper
    than 12-2 but costs almost double ($120 vs. $70 per 250' roll). And,
    10-2 is $135 per roll, so yes, *DOUBLE*.

    When *was* the last time you bought this stuff? You really need to
    get out more and bitch less.

    When cornered, change the subject. Figures.

  8. Pressure would remain constant. Flow *can be* constricted over that

    Think hysteresis. Pressure does have a slight drop as one "loads" the
    available flow (stored energy). Once you cross that threshold and the
    flow rate becomes the bottleneck, pressure can drop on a continuous duty

    Just run plastic pipe. They even have tool-free fittings for pneumatic

  9. Pretty expensive at the per foot level compared to modern plastic

    And hose would work too.

    The plastic (PVC) I've seen is *not* recommended for air supply. It
    will shatter. Do you have other information? Cite?

    Oh, look! Grainger wants $141.10 for 250' of 12/2, TWICE what HD gets
    for it.

    Did you check Ebbay? :)
  13. Then, water pipes must not be the solution of which I speak.

    There are plenty of factories and production labs piped out with
    plastic 1 1/2 pipe and hand swage fittings. It is, in fact, the de facto
    standard in any industrial environment these days. at least where we are
    not worried about some dope on a tow motor banging into it.
  14. Guest

    No. Why would I?
  15. Guest

    That was two years ago. Tell me what you paid last week.
    The point stands. Cost isn't just material. It's volume, as well.
    Expensive commodities sitting on the shelf cost more than those that
    fly off the shelf.
    Get real, Michael. You lost.

    Well, you wouldn't unless you were looking for a bargain.
  17. Guest

    A bargain on safety relates stuff? FleaBay for electrical hardware?
    No thanks! I don't buy that stuff from Harbor Freight, either.
  18. I never suggested PVC, the idiot responder barked off about it, then
    you, the other idiot in this equation.
    I do not need a primer, dork. I am not the pair of idiots going on
    about PVC pipe.

    Because I *do* know what is in the channel. And I know what the physics
    are too. I used to make home made cannons of various sizes and proof
    them with shotgun powder, which is much more powerful than black powder.
    If they survive the heavy load, hot powder test, they'll survive black
    powder and no loading. But the failed units tell quite a story to the

    Only a couple orders of magnitude more pressure...

    Have a nice day.
  19. Only takes about a fifteen foot length to toss over the rafter in the
    garage. One loop around the neck, a little hop off the step ladder, and
    you won't need any wire any more.
  20. Guest

    Perhaps not, AlwaysWrong, but you supported the idea.
