need tip on how to hold pieces for TIG at odd angle - ?modeling clay?

[d.eglen]

The project I'm doing is TIG welding two 3/8" mild steel square bars on an angle to a 1/2" square bar. The drawing is easier to understand than my explanation. Top bar only is illustrated.

the right angle pipes/angle iron, c-clamps, and vise grips I'm using for a frame just don't get the angles right.

Could I safely use modeling clay or something like that to hold small pieces at an odd angle just to get the tack weld made as long as I keep the clay away from the weld?

Would these help ? Posting from another site.

I don't believe that welding finger will help much in your case. If you have a lot of them to make, you should make a jig. If it's just the one, I usually just grind the angles I need and hold them together by hand for a tack. Then you can bend them a little to get the final angle and weld.
You've got a tough problem, I admit.

This universal clamp may be just what you need.

I made up the pieces today of your design, but I don't know how to do the washer part to get it to hold.

The washer is a shade larger then the material that it slides on. It just binds on the round stock by gravity being on a angle. Your washer inside diameter maybe too large. You could try a small '' C '' clamp or baby vise grips on shaft to hold weight too. Hope it works.

I looked around other forums and eventually was led to this youtube video.

pretty cool solution that would find many uses.

This works on many projects. Great advise.
