Jack (?) in Hawaii mentioned using a small brake for this. Yeah, I
know about that; I was thinking of an alternative method, something
more geared to production. What I described is (theoretically) a two
step process. 1) cut and score blank with pancake die. 2) form part in
press with urethane . Maybe sharpen up the bends with hammer and tune
with pliers. Someone wanted to make 3 sided ‘boxes’ without soldering,
is how this came up. Dar
