    Thanks, David.
    Rectangular SS tube like that is too expensive and for this installation, too heavy. I intend to inset the supports like your drawing, the distance will be determined by ultra precise...

    Hmmm. How long was the plant operating? With the three notches maybe it was used to assemble propeller hubs?

    Ha! You noticed the decline, eh? I told my wife that any day now she'd not be the only one to see it!:eek:
  4. No thanks. If this were being offered to the...

    No thanks. If this were being offered to the public for a price, proper documentation would be necessary. But it isn't. From post #1:


    I'll test thoroughly, use good judgement, and take...

    Thanks for all the info. I"ll check on the cost of sch-40 ss pipe, but I suspect its very high. Another complication is that they want to be able to lower the rails for the kids. Weight-wise the...
  6. Yes, thanks. I don't mind if the deflection is...

    Yes, thanks. I don't mind if the deflection is high under such momentary load, I just don't want anything to 'bend' permanently. I have also considered arching the rails, say 6" rise over 10' (12"...

    Thank you, Mr. Bronson. I've suggested sch-40 and powder coat but they're still hoping for SS. If not too much work, could you estimate, say 2 1/2 or 3" thinwall 304 @ 15' span?

  8. What is the bending strength of 2" OD 304L tube; .065 & .120 wall?

    I've been asked to fab a set of 'adult-sized' monkey bars for a Christmas present. The user is 6' 2", 180lbs. They'd like the run to be as long as possible, up to 20' but at least 10'. I've requested...

    Having watched the automobile tailpipe expanders work, is there any reason you couldn't put something like that on the end of a smaller tube and use an extended mandrel draw bar? You could probably...

    Sounds fine to me, but it might not be feasible. It appears that the current 'material' classification is automatic, based purely on post count. Inserting something else into that field manually is...

    I use the exact same compound angle for both (using a wedge-type QCTP) and will often run male and female threads in one setup. I use a start position at least one leadscrew thread ahead of the work...

    My preference is for 4500K, 5000K max. The 6000+ 'daylight' color irritates my eyes after just a few hours. Too blue.

    OK, I've got the red face... didn't pay attention to necro-post status.

    You can get rid of the cord real easy. I use two retracting extension cord reels, one runs along the wall and connects to one that runs along the beam. You just need to take out the pawl so they are...

    The 2 yr old Quincy at work, 7.5hp/80gal is not quiet. It turns pretty fast compared to some older models and therefore makes more noise. We also have a Speedaire (Gardner-Denver) of the same HP and...

    That only holds up if the male and female threads are of the same material. Most people don't have a feel for things like that, and 3 aluminum threads mating with a steel screw will die a squishy...

    The worst tooling I've ever seen has come from India. The chinese 5-Cs I got recently just to see were also pretty bad. Not ground through the grip area, off center slits, not deburred etc. and most...

    I use this phone: KYOCERA Torque X01

    It is the only phone I've had that stands up well to the shop environment. The IP ratings ensure that the dust won't get into the electrical parts but the...

    Well, around here 20lbs of liquid CO2 is around $15 while 240cf of Argon is $65.

    Try a piece of cellophane tape over the hole or grill. It typically won't affect the sound much at all, and metal dust can be wiped off. It needs to be the thinner, matte surface tape, not something...

    Straight oil of any common type will not cool nearly as effectively as a water/coolant mix. The lubricity may go up, but the cooling will go down. Its difficult to quantify exactly because with added...

    That is a great chart. And looking it over I take back what I said in post #5. It might not be bad at all. Sharp cutter and coolant may be quite workable.

    Ken, that was my first thought too, but the OP only mentions cross-slide feed. If the long-feed doesn't slip it may not be the clutch.
