Thanks

I've done it with pieces of soft, rounded-edge wood in the vice but when I needed to make several of these swages on a different project I made some dies out of aluminum angle. I'll see if I have a photo somewhere.

Edit; went out to the shop for a couple of photos:

Default cool technique

Thanks Sam, great timing. I've made a few of these that have not worked out, and have recently ordered some more tubing. Thanks for sharing your technique - very clever!

Adding to the noise...

Decades of working with 300 series stainless steel (what the hangers supplied by Vetterman for my exhaust were almost certainly fabricated from) made me leery of using it for anything that involved possible large amplitude vibration mixed with abruptly changing cross section (cue Sam's swaging trick), sharp edges, etc.

I happened to have a piece of 3/8" OD x .035" WT (I think) 4130 chrome moly tubing lying around from some long forgotten bicycle frame project. Perfect. Enough to make all the hangers I needed. The stuff required heat massage to flatten nicely but 640 hours later no failures. The rust I feared turned out to be a non-issue. My Lyclone doesn't leak much but it dispenses just enough anti-corrosion fluid to keep it at bay.

i went another route. took some solid steel rod of the same size and flattered the end with a sludge hammer on some steel plate. 5,000 hrs later no problem. stronger is better. impossible to break.

I just had two adel clamps where the hangars attach to the engine mount break.

What many of us have done is abandon the "attach to the engine mount" method. Instead, all the exhaust supports (still with isolating rubber hoses) are attached to the engine, usually a couple of sump bolts. That improves the probability the tail pipes will be vibrating in concert with the engine and reduces the chances of broken mounts.

Just a reminder...there are other exhaust hanger designs.
