I've got the hand-tool version. It has two sliding formers (15mm + 22mm)

not really worth the effort most of the time.

As I said it was easier with the older soft copper pipe. Annealing modern
stuff would probably help. But as you say probably not worth the bother.


Now that we all have SDSes, I wonder if the method might be worth
revisiting.
