shop press brake

[nc9933]

I have one of those 12 ton shop presses that is about 100$. I am looking for a small brake
attachment that would fit in the press ,have a pipe on top to catch the pipe going down
and sit on the metal shelf below. no more than 16 inches across.I have seen some bigger ones... I'm l,ooking for a small one.. any ideas or links..??? thanks

I'm looking to do something similar, but I haven't built any tooling yet.

Here is my "ideas" page:

how well does the composite bottom die work? I've read about it on the internet, first time I've actually seen pictures of it in use.

that simple yellow one from metal illness looks good. There doesnt seem to be any cheap(60$) ones available.... can anyone build me one for that 16 inches across...??
otherwise I,ll try one by myself. btw where do people buy scrap or new precision round steel bar like you would use in these projects??? link....

mcmaster.com or my local steel supply. For small orders, I don't bother the local supply, I just get it from mcmaster.

Ground and polished shafting or drill rod is what your looking for.

EDIT: looked again, that's nothing precision, I would just use round bar, probably 4140 because it can be welded. I make tools out of 52100, but it's concidered non weldable, but decent to machine and after heat treat, hard as a rock.

mcmaster prices are absurd. they sell a piece of plate for 50$
I could get it at Pacific scrap for 6$.
the days of double pricing are Ending..... this little depression is going to squeeze the BS
out of any outfit who tries it...I'm cheering it on YEAH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What is pacific scrap? Do the have a website? I'm guessing it's an akronm for something else?

Here's one I built a while ago. 24" capacity. The top die is 3/8 and the bottom v is machined from 2x2.
It sits near floor level of my hydraulic press and is driven by an extension, leaving my press free for other jobs.
The design has it's limits (though it can be opened up wide relatively easily to remove a stubborn job).
I have shorter pieces of the 2x2 lower die made as well.
