A guy
on a Mustang list had a simple method of adding a bead without a tool. He
just cut off some pipe and used a pipe expander to make it just slip over the
existing tube end and then rounded it a bit and soldered / brazed it in
place.
Hum-m-m; beading tool, or pipe expander,
– which would I like to have . . Just kidding; I think I
could take a piece of pipe down to the local muffler shop.
