Good. That's what I thought you'd say. I just need to keep calm and wait it out. And, like you said, pile up a bunch of work to systematically just work through.

I've posted recently regarding welding SS rod and tubing, both welding and flame straightening. I've looked up some other videos on the latter. Big question: is there any liability in quenching with cold water hot SS (or mild steel or aluminum for that matter) immediately following welding or flame ...

Good. I'll post my results. I must say it's quite satisfying to be able to perfectly straighten deformed metal.

I'm welding 72" x 6" frames from 0.375" stainless steel tubing with a 0.035" wall thickness. If you can imagine a trombone - the part that slides back and forth - this is what my pieces look like. They're lighting diffusion frames for the film industry. These SS tubing frames wel...

Thanks VERY much for the feedback. Yes - one of my pet peeves is that I can't just weld. It's two or three dabs and then reposition. Couple that with my inherent lack of patience and it's quite trying. It would be terrific if I had the equipment to fit these things up and reposition them perfectly b...

I'm going to try the Jazzy 10 (just ordered one). Can you take a look at these pix and give me some pointers? The middle one is rod to rod. The others are rod to tubing. I don't think I'm doing awfully and the welds are holding but man, this takes too long! THKS! Jon [attachment=0]DSC00010.JPG[/atta...

I'm welding 3/8" SS tubing, 0.035" wall with a stubby gas lens set up, #8 Furick glass cup, 18CFH AR. I'm wondering if I should be using a bigger cup but am concerned it would just get in the way in these tight, tight corners. I think I'd need to much stick-out. But I'm finding that the mo...

That helps. Thanks very much. You're right - 5356 @ 3/32" is what I have to hand. But I also have plenty of 4043 @ 1/16" so I'll just stick with that. With my machine set at 185 amps, I'm not close to full penetration on this 1/8" wall material interestingly enough but my welds are ho...

Today I'm welding 1" square aluminum tubing. 6061, 1/8" wall. I'm welding a bunch of rectangles that are about 18" x 8". So my main members are 18" and the intersecting members are 6". I'll get some pictures but in the meantime, hopefully this paints a picture. I'm tack...

Got it. Very interesting. Makes perfect sense.

cj737 and tweake, some really good advice here. Thanks very much. I hadn't considered using thicker filler as a laywire technique. I'll give it a shot. I do have plenty of 1/16" 304 rod. When you say that the notches need their ends ground to ensure a fillet weld all the way around, can you cla...

cj - Again, thanks for the advice. To clarify, the tubing butts into the solid handle and the tubing is "notched" to fit as tight as I can get it. If you're familiar with a C-stand (film industry tool) you'll get the picture. The solid "handle" is essentially a piece of rod stick...

Basically got my notching rig set up and it works nicely. Still working over the bending side of things but I'm in touch with Bend Tech and it sounds promising. So I welded my first frame together this morning and I must say, it was a b&*ch. The handle for the frame is 3/8" stainless rod (s...

Good idea. Did some of that already but burned through a bit too much tubing... All good though. But I agree, nothing like finding out for yourself.

cj737 - There you are again! I looked up Bend Tech. Had no idea they existed but they seem highly competent. I'm in touch with them on their software so I can get the right package. Thanks again for what you're doing out there for us new guys...

Long shot on this forum but this is for anyone who has experience fabricating using thin wall tubing (0.035" wall) with small tubing size (0.375" OD). I'm making flags for the film industry from this material. They are 48" long and 5.75" wide outside-to-outside, rectangular. They...

cj - Thanks very much. I had considered hole saws but could never find one at 3/8". I'll check the Starrett site. I do, however, have four brand new 3/8" tungsten carbide burrs that I think I could jig up in a die grinder. As long as I can hold it still and feed my tubing into it that migh...

I'm building frames from 3/8" stainless steel rod and 3/8" stainless steel tubing @ 0.035" wall. I don't have a notcher so am having to notch the intersections of these items by hand. I can do this with a cut-off wheel I suppose. But is there a better way? Any ideas would be appreciat...

Good. Going over to do it right now. I'll let you know how it goes. But certainly no problem clamping the DP out of it! ;)

For what it's worth, if you're welding 1/2" aluminum, you're going to need some amps. When I was starting out, I tried to weld 1/2" aluminum with a 175 amp machine. Didn't even come close to any sort of decent penetration. What is your machine set at, amps-wise? Never mind voltage. Secondl...

I'm welding 1.25", 14ga square steel tubing. 2 8" pieces cut at 45 degree to make a corner. What's best practice in terms of welding sequence to avoid the dreaded shrinkage that will leave me with an 85 degree corner when I'm done? Fillet first? Tack all 4 corners and then weld the sides? ...

Anyone had any experience welding A513-2 CREW steel tubing? Can I TIG weld it with ER70S-6? Or should I just stick with DOM (A513-5) which I am sure is easily welded?

I'm going to leave it alone and go with stainless. It's just too risky. 4130 would be nice but it's a little pricey. Thanks cj737.

Anyone had any experience welding J524 low carbon steel tubing? I'm assuming it CAN be welded. Can I use ER70S-6? My use is not structural at all. I'm fabricating lighting diffusion frames from 3/8" OD, 0.028" wall J524 tubing. Total weight = less than 5lbs. I was trying to get mild steel ...

You know, I considered that. Drilling right through both walls of the tubing. I thought it would be more time consuming but considering the time I'm spending to straighten out my 20' boomerang, I'm probably wrong about that...
