    Pipe Clamp

    Those of us who do pipe welding for a living will probably have one or more 3-point clamps in various size ranges to clamp butt joints in position for tacking. I don't know if Uncle Sam has them, but a clamp for 1/2" pipe has not been available, so we use vice grips or similar 2-point clamps to line up and hold the joint. Doesn't deal with hi/lo but we get the job done.

    Recently a buddy of mine found a 1/2" 3-point clamp, manufactured locally and bought it. Works great, he said I should get one. $250. wtf. Not paying that for a clamp so I decided to make my own. It's not a copy, I haven't clapped eyes on the one my buddy bought. I sketched up what I thought would work and modified it as I went along to get all the angles right using off cuts out of the scrap bin and fasteners on the shelf.

    Works good. Very happy with it. I'll have a go at hot bluing it. I spent more time than what it's worth probably, but I have time at the moment due to the wuhan wog, and I still have the $250 in my pocket so all good.

    It's soaking in oil right now after hot bluing. Monday I'll reassemble and post up another pic of the completed clamp.
    It clamps up to 1-1/2" pipe to my surprise. That completes the full range for me as my big clamp does 2"- 8". I can now reduce the number of f-clamps and vice grips in my tool bucket.

    That is a nice clamp you made.

    I've got a few shop made tools that I find I'm always reaching for. Some I made to save money, but most of them I needed ASAP and buying one meant getting it shipped, at least 24 hrs out, make my own it 3-4 hours and get the job done.

    That's nice.
    I have some vise grips with movable taps. I welded short angle iron pieces to them. They work well. For small round I have vise grips with 1/2x1/2 angle.

    Re: Pipe Clamp

    Very cool. I had made a tiny version of this, not exactly of course, but to simply hold smaller tubing (< 1.75" OD) for tacking/welding about 6 yrs ago. I think I still have it somewhere.

    I think with a small modification to the (spreader bar section) design it could be a gear or bearing puller very nice

    Really nice work

    Our guys have a couple of small clamps like these for 1/2"NB

    The Scissor clamp design works quite well for joining straights.

    Re: Pipe Clamp

    good job fabbing it yourself. i'm surprised anyone with a saw and welder would purchase one but sitting at the computer in the ac everything looks simple.
