Hello all, I am planning a project that requires a 13 inch square
piece of sheetmetal to have one inch on all 4 sides bent 90 degrees,
so that it forms a 12 inch square pan with 4 one inch high sides, I'd
like to use a brake to do this and I can see being able to bend the
first two opposite sides, but how would I bend the adjacent sides?
Thanks in advance for your input,
Gene

You might be able to raise the clamping leaf enough to put a 12" piece
of bar or key stock under it at the bend line. I built a brake this
month with the clamp easily removeable so I can use scrap steel blocks
and deep-throat welding clamps to fold up special boxes.

Crease the two difficult edges to start a sharp corner, bend the other
two completely, finish by clamping the box between blocks and bending
with a rubber hammer. I've been bending the sill corners of aluminum
window trim this way using cheap 1-2-3 blocks.

The 3-in-1 combo sheet metal machines allow you to move the fingers
around to bend a box. A real finger brake is wonderful if you can find
an affordable one and have the room.

How many would you need? The multi use machines have removable fingers
for this. Or a vice and a couple pieces of angle and a rawhide mallet
would work as well.

If your using thin sheet you could also make a simple brake by cutting
two slots for the edge bends in the bending die on a small brake.

You didn't say how thick the metal is, what metal it is our how accurate
the bends need to be. If you don't need a lot of accuracy, you can bend
the other two sides by just clamping the unbent 3rd or 4th edge in a
vise and bending it over with a hammer.
If you haven't bought the material yet, buy it from a fab shop and
have them make the bends for you.
