Build Yourself a DIY Press Brake

Some people have a natural ability to comprehend and learn quickly.... and then there are engineers who spend lots of money and time trying to learn and never do. But, then again, they're always right because they bought a diploma that says they're qualified.

i want to made hydralic press brake 8foot 4mm banding .so i want design diagam of press .

To Jose & Tom C & anyone else interested in the steel-making process - Tom C is an engineer, so makes the process of making steel a lot more involved than it needs to be. For dona hey centuries, people made iron & steel as an art form & the best of them produced reproducible products. I know this because for nearly 40 years, I worked as a blacksmith - taught it, demonstrated it, made a good living at antique metal restorations & reproductions.. and eventually, got curious about how wrought-iron-the-material was made & built a very small foundry. There are still some people in England who make wrought-iron-the-material.. they learned from guys who were in their 80s & 90s. The old guys call it "dancing with the iron" & they made some gorgeous material. And after making iron, they alloyed it & made steel of various carbon contents, & then went on to make some low-level alloys. With a rolling mill, they made sheet. These things have been done for some 4000 years, takoszja (grandchildren) - it's hard work, but you do not need a "modern industrial plant" to do it. Now - as to whether the information Jose wanted is available online or not, is another question. But "probably".

Hanh Paul. I've been searching for this set of plans for months & stumbled across them here. What luck! Pilamiyaye! / Thank you!

Now - I need to either build a sheet metal shear (benchtop, 12" wide max stock width, 24 ga. max thickness) OR modify a stack paper cutter that I have. Currently, the blade moves just enough that instead of cutting the stock, it bends it, so must need shimming. But is this enough, & if it is, what is the shim thickness needed & how do I determine it? Any help will be MUCH appreciated.

A little late response but harborfreight.com sells an 18" brake. No clue how decent it is though.

Anyone know where one could buy one of these small Brake Presses if one had not the time or skills to build it? All the ones I can find online are huge and elaborate.

Any help would be appreciated!

Dear all,
I have a auto exhaust manufacturing comapny. i have to make elipticale shape of silencer box. i made it from plain metal sheet by 3 step.
Actually i want to know how can i make eliptical shape box by one process from plain metal sheet. its thickness is 1~3mm Mild Steel/Stainless Steel.

Please informe me if any body knows

Jose, L.S. - speaking as a metallurgical engineer, the making of steel is a very elaborate process, even before you get down to the rolling into sheet metal.

One of the best books to describe the process was printed by US Steel Corporation and is titled "The Making, Shaping and Treating of Steel". It is a large thick reference book that should be available at most larger libraries or maybe on loan from one.

Good Luck, It took me 6 years of engineering school to understand the process.

Im working on a paper to find out the process of making sheet metal. From rock, to liquid, to mold, to store. Well we all know the process, but i cant seem to find any good sites. maybe you can give me one or two that you might have ran into.

thanks

Could any body help me in building a large sheet metal brake from scratch? Thank you

Funnily enough, Derek, there's a post somewhere around these blog parts to a guy who made his own laser cutter.

Yes but the minute you have this thing, you want to make a box 18 long. So then you make one 24" long and low and behold you need something 2'4". And it keeps going. I've managed to get keys to the local shop by promising to teach the green sods basic metal stuff on Monday nights, but they only have a 3' brake there. Luckily Kobi took pitty on me and let me come over to Boyer Metal where I got most of my bending done on a 6' break except for one part that still was too big. Luckily I was able to beg time on their nice 14' break for it. Seems to have me covered since the plasma table will only cut pieces up to 8'.

I do have a little 14" shear that comes in handy for trimming those last few triangles to fit in the geodesic sphere. Still would love to have my own plasma cutter though ...
