I found these plans a couple of years ago and downloaded them. I can't upload them without express consent of the site but I can't find it again. I can give the plans to people as an indviual but there is a problem with posting them. I wish I could have rembered where I found them and gave yall (you all) a link. There were some other plans on there also for sale.

I built one a couple years ago, and I wouldn't do it again. When I get enough cash, I'm going to buy a small commercial box & pan brake. I built mine from a book full of shop tool plans, that has been around for a decade or more, and I'm sure lots of you have seen it. The biggest problem, after I got it built was that the pivot point for the "movable bending plate" was too far away, and I had to tear it apart and rebuilt it. It works better than 2 pieces of angle iron in a vice, but not a whole lot better. Also won't bend a nice tight radius, because of the aforementioned distance to the pivot plate. I think that is the most important design element. Good luck. John V.O.

I just managed to put a couple pics of my brake into my gallery, if you want to have a look. Maybe tomorrow I can put them onto this post, unless someone else wants to. I gotta go home, getting very hungry.
The plans say it is supposed to do 16 gauge, and its 52" wide. It really doesn't want to do that. It will do about 36" of 16 gauge somewhat reluctantly, though. 18 gauge no problem.

Here's the write-up on the brake plans as built by Holger Stephan. Unless you can get 1/2" angle iron, it doesn't seem like it will work steel vary well. Sounds like he had problems with the constuction too.

Save up and get a box brake! :D

Hello warrior (I don't know your name?)

If it's 2' -3' of light sheet metal you want to bend, there are some light duty, low dollar bench brakes you can buy already made. I've seen them in catalogs, and on the internet, but I don't remember where. Some of them looked very simple. A good quality box and pan brake would be even better.
Even if you have plans, try to look at some existing manufactured brakes small or large to make sure you understand how they work.
They may look simple, (and they technically are), but if your'e off on the key details, your bends may not bends. John V.O. testified to that!
Coming from someone who has built a lot of stuff that could have been bought, I would buy it. But if you want to build it good luck.

I have made several folders, from 12" to 5' wide.
the last I made was to do 36" wide bends in 18swg.
It's reasonably rigid, i have no idea what the cheapo
things made from 2" angle are like but I woudl waste my time trying
to make a folder over a foot wide with a 2" clamp.

I did do drawing of the parts but never finished the drawing.
where possible I bolted it together, the steel will probably be required for something else some time, the hinges are adjustable in all planes, the clamping beam and folding leaf are also adjustable.
It's pretty simple and you should be able to copy it or get some ideas from it.
