I am in need of a press brake for my stoves so I am working on a design. It is like the large Hyundai press brake next door in that I can bend square tubes and open on the sides unlike the usual shop press conversions.

Specs are 50 ton manual bottle jack, 24 inch length with changeable V blade to make box bends in steel plate.

Target is bending more than 90 degrees with a consistent radius not too sharp but not too round either.

I would like to bend at least 6mm plate with it.

Materials are 2 sheets 5mm plate, high strength bolts, 50 ton bottle jack, hardened steel bending tooling fabricated at the tool and die shop up the street.

The design will be a C clamp shape with 2 arms. I will cut that part on the CNC. Each arm will have 3 layers of 5mm plate with the arms separated 1-.1.5 feet and cross braced.

It will have minimum of total 15mm x 12 inches thick steel plate total to carry the load at all parts of the C clamp shape. Basically it is a giant c clamp with a press brake blade in it.

The projected build cost is about $350-400 dollars including powder coat.
