Hello,

I would like to start making brackets and other metal items. Would
anyone have any links or books on metal forming and the tools needed? I
would like to know how how they form complex forms like.

determine the gage of metal needed?

Right now I am looking at a 3 in one tool, which can do 16GA. Would a
tool like this be the most useful? I have seen a brake which can do a
thicker gage but they seem to really jump in price and weigh just as
much. What can I use if I have a thicker gage?

The metal I would like to work with are for robotics and just general
purpose brackets.

Thanks,

Those parts are made from photo-etched blanks and then bent on a much
more refined instrument than a 3 in 1 tool.

A 3 in 1 tool _may_ get you what you want, but in my (admittedly limited)
experience I can get far better control over the bend angle with a box
break than with the 'V' bender in a 3 in 1 tool.

I don't know where you'd get a decent box break for less money than a
good used car - this is just as well, because I don't have room for one
right now.
