Ed you can do the same with a good high temp epoxy and the same wire. (J-B weld)  I would probably prefer your method though. I believe you can get the low temp braze stuff from aircraft spruce now.

Subject: [FlyRotary] Beading a tube - sort of: [FlyRotary] Re: forced landings

Bill, here is something you might try if you can not find, beg, or borrow a big expensive beading machine.
 
Take some soft aluminum rod of the size you want for a bead.  Bend it around the tube and cut it to a length where the ends of the rod meet around the tube.  Position the rod ring near the end of tube and clamp it in place.  Then  use some of the HTS- 2000 aluminum brazing rod (other stuff may work, but this is the only rod I’ve ever had any luck with)  and a propane torch to braze the rod on the tube. A bit of touch up with a fine file or sand paper and you have your bead.  A bit of work, but not that hard and if you don’t have access to a beading machine one way to get the job done.

Dave’s number 4 below brings up a question I have been pondering.
 
How do you put a bead on the ends of aluminum tubing so the hose will not slip off???
 
My tubing is inch and a quarter and probably 0.060 thick.  Suggestions appreciated.
 
Thanks,
Bill B
