holding mandrel pipe together for tacking

[that-guy]

so, working on stainless exhaust and aluminum turbo piping, i often come across issues with getting the pipes to stay where i want them so i can tack them together. i use masking tape most of the time, but sometimes if the shop is really hot, the tape will not stick to the material. what have some of you used in the past that has worked the best???

Stainless worm drive clamps, I punch a hole every 90-120 degrees to allow a place to tack.

You might get some ideas for something you can make from here.

I use the vise grip type for tubing. works great for most any size i use other than 3" and thats fixed with the bigger pair.

If i can i use a bit of tube the ID of the tube im trying to weld's OD, then cut that piese of tube in half, and clamp that to the tube i want to weld, maybe via a hose clip or 2. That then acts as a saddle to rest the tube to be welded. i know it sounds a bit half ased but it works for me.

well, i have used silicone couplers before by cutting a simple window in them to allow for the tack. i guess i should reiterate my question by asking how it is that people hold two pipes together that need to be tacked somewhere on the bend?

this is exactly what I use on my stuff;

I use some flat stock on each side of the tube clamping each end of a bend using kinda what fits to get it done, like splinting a broken leg.

Ditto.

I keep a few stainless angle offcuts in various sizes for just this purpose. Still have two pieces of 150mm angle I used to align some 300mm tube I hade to do. Just make sure there is no burs on the ends of the angle sections as they can throw out the alignment.

Exhaust welding band clamps can be purchased or easily made. Summit has different sizes.

this rendering better illustrates what i am asking...these are two pieces of tangent 90* pipe butted up to one another with no straight and cocked at a weird angle...if you didn't have the choice of using masking tape, how would you do it???

with the strong hand pipe clamp

I know you will think I am crazy, however for just tacking I have a large sandbox that I submerge the 2 pieces into. The sand holds the pipes exactly how you want and allows you to easily tack it.

This technique of holding things was shown to me over 40 years ago at the old Brooklyn shipyard (Navy Yard) by a guy 90 years old at the time. It has never failed me.

That is GENIUS, I will defiantly steal that idea, thanks for sharing

that is a simple yet inovative idea...thank you very much for sharing (heads to beach with a shovel and pale)

+1 thanks!

I clamp most pipe in the HF rotating vise, and lay the other half on the table. The vise is mounted on the side of the table to help with this. The other thing I do is tack one end of some scrap rod/bed frame angle to the steel table top, the other tacks to U bolt style exhaust clamps. The clamps hold the pipe and this works well as a simple jig if I am making duplicates.

I have used blue tape. I tape it in place and then use a utility knife to remove one section at a time

Way to go! endorsed.

Call me old fashioned or non-gizmo, but I just use my free hand. Has always worked for me. Mike

That's what you say but I see a swivel head vise in the background

Nice table by the way!
