Hi,
Watch the local shop auctions. I have a Pex, Stow, Wilcox # 100 set I picked
up at an auction for around $50.00. May be a little big for some shops, they
are about 3' wide. The front two rollers are vertical with screw adjustment
for material thickness. The left side has a latch disconnect so that pieces
rolled into a circle can be removed without damaging the formed metal. The
back roller is adjustable to control the tightness of the curve. It is also
differentially adjustable so that cone shaped pieces can be formed. There are
also wire bending grooves on the front bottom roll.
Also watch for "tinkers tools" the hand seamers and rollers used by tin
smiths and sheet metal workers for making all sorts of goodies. They often go
for very low prices because they are not amenable to computer control, thus a
semi-skilled human is required to operate them.
Keep your steam up!
