    Default Homemade small press brake ?

    Has anybody made a small press brake the sort one would use for bending small parts to make brackets and like ?

    Something like I found on ebay.

    Personally, no. It's on my round tuit list though. I've seen shop made pressbrakes up to +/- 60". Most dedicated press brakes start off with a H frame press http://www.mad4wd.com/gallery2/main.php?g2_itemId=463 . The largest had 4 - 3" x 12" hydraulic cylinders on a massive upper die. http://www.montgomeryauctions.com/up...3/P1010162.jpg

    Shop outfitters has one on their site http://www.shopoutfitters.com/Catalo...roducts_id=194 that should be easy to reverse engineer, but I can't for the life of me figger out how they think it's worth $689 ?!?

    I tried to find some pictures of the brake I saw that used 1/4" thick angle for both sides of the brake, but the pics have been removed from the photobucket account. The anvil side was made of two angle sections back to back with a spacer between. The maker reported it worked well for thin materials.

    I've toyed with the possibilities of a lower die made using parallel pieces of round stock spaced apart by 1/4" or so, but haven't done the experiments yet.

    I priced a few - then made this:

    with a 6" bench vice and scrap angle iron, steel, clamps, some 2x4s and a rubber mallet.

    Do you have plans for the bench brake? I'd like to build one for flashing in addition to the pressbrake for up to 1/4" or 3/8".

    I built a highly modified version of the Gingery brake, it works well, worth the cost of the book.

    Here are a couple that I have made.

    This one is for use in a hydraulic press.





    This one is portable. I built it around a H.F 12 ton air/hydraulic bottle jack.

    I'd like plans for Falcon's press if he has them. I'd imagine tolerances are +/- .001"?

    :-) That's my method as well. BFH! And if that doesn't work, you get a B'erFH

    Check out my small sheet metal brake as shown in the "Home Metal Shop Club". Full plans are available on the site in a zip format.
