Has anyone any good links to simple sheet metal bending and laying out
practice on the web? Having now at last acquired my Gabro BF1000 it
would be nice to be able to get the bends in the right places g I'm
hoping
to be doing a few doors with a return bend edge - ie a channel section
all round.

(The BF1000 is a manual 'hinge type' folder that can do box pan by
cutting a length of angle to the internal box size rather than having
interchangable fingers)
