Press brake

Any of you guys have one? They look real handy to bend 3/16 -1/4'' steel to make make brackets & mounts.

any press brake that will bend 1/4" steel will cost far more than the average hot rodder can afford thats why a decent TIG welder and at least a drill press but ideally a milling machine are a better value, youll need a 25-40 ton rated press brake to easily bend 1/4" steel of any size,once you start talking larger sizes of 1/4" sheet cost jumps astronomically and the DIES are extra

If you need to bend 1/4" steel an O/A torch will do the job a whole lot cheaper and with a cutting head will do a lot of other handy jobs

I bought a 40" brake a few years ago, it's pretty killer. I have made some really cool brackets with it and have used it to make patch panels for body work too. I bought it used from a local guy and got a cool cart to keep it on so I can roll it around if needed.

It won't do anything crazy like 1/4" but I don't know of a homeowner machine that will do that.

It also has a roller and shear on it. Here is an old picture of it when I brought it home

How about one like this. I run these all day, everything from 14 foot 16 ga. up to 1/2 inch, sometimes thicker.

A press brake, also known as plate bending machine, is a kind of machine tool for bending sheet and plate material, most commonly sheet metal, material could be normal steel, stainless steel, aluminum and so on. Regularly, two C-frames form the sides of the press brake, connected to a table at the bottom and on a moveable slide at the top. The bottom tool is mounted on the table with the top tool mounted on the upper beam.

A Press brake could be described and distinguished by basic specifications, such as the force or tonnage and the working length (length of plate sheet). Additional parameters include the amplitude or stroke, the distance between the frame uprights or side housings, distance to the back gauge, and work height. The upper slide usually operates at a speed ranging from 1 to 15 mm/sec.

There are many different types of press brake as described by the means of applying force: mechanical, pneumatic, hydraulic, and servo-electric. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper slide. Servo-electric brakes use a servo-motor to drive a ball screw to exert tonnage on the ram.
