Question for you motor guys

[Matheny 514]

You know you can do it !! Just my opinion, but tig has always been the easiest for me. You are in control of your speed and filler feed rate, and if ya have a foot pedal control, you control the heat! Once ya get the hang of it, it'll be the only method you'll want ta use. Like I said, cap the pipe ends of with a baggie or tape or something, and purge the air out with argon ant the bead indide the pipe will be as clean as the outside. Back in the day, I used to weld cryogenic transport tankers, and all the stainless or aluminum inner vessles were tig welds with full x ray testing. Got faith in ya man!!

, tig is the easiest for me as well.

If you can oxy-act weld, tig is a no brainer.

Take it to a shop and have it welded properly. JB weld on that would be like pissing in the wind.
Also, find what stress factor is making it crack there.

Really good advice here. After all that bear is worth it too jmo.
