Swag off-road press brake kit?
 
Swag off-road finger brake kit? Has anyone seen, used, or owned one of these swag off-road, press brake kits? I'm wondering how they work, and if they're worth it. It looks like they are able to bend 3" wide 5/8" thick steel and obviously wider if thinner. I already have a 20 ton press.

I have the solid blade version. I seldom use it but it when I have it worked well. I have used it to bend quarter inch plate and strip stock as well as 16 ga. Stainless pieces.

There are quite a few YouTube videos on them out there.

My take-away after watching a number of them is that they are not ideal for thinner stock, as imperfections between one finger profile to the next will be visible in the bends.

So, the thicker the metal, the less those imperfections will reflect through.

Yep, I have used them have not bought one.... the cost was too high for my blood. but, I did buy some dies with different radiuses for both steel, SS, and aluminum.
I just have not gotten around to making the press just yet another one of those projects that get's left in the dark. that is, until, I absolutely have to have it.. but if you have the tools to make it you can make your own their not so complicated to make and you can make it close to the with of you press break.

$300 is a bit pricey but if you don't have access to a mill it does become more reasonable. I have the steel to build one, it is on the 'to-do' but mine will be a bit wider.

Google "press brake tonnage chart"

Rough rule of thumb:
1. standard bottom die opening is 8 x material thickness
So you know how short of a leg you can bend.
2. using the 8x standard, 1/4" plate will need a 2" wide opening,
and will take 20 tons per foot of bend.

So 1/8" plate will take 10 tons per foot.

adjusting the bottom die wider/skinnier will change things.

Here's the calculator that I use all the time--very handy. Accurpress is only a few miles down the road from our shop and their die shop usually has a good selection of "shorts" available. We've picked up a great selection of dies for our little 4 ft. Promecam brake. Everything from 3/4" wide to 4" wide in a variety of lengths. We also have a few home-made bottom dies for some special applications that have come along.

We bought this brake on a whim about 8 or 9 years ago and we've been amazed at how much use we've actually gotten out of it. We went to another business to look at a No. 3 Diacro bender that was for sale and the guy we were dealing with asked us if we were interested in the Promecam as well. It wasn't working right--wasn't making any pressure--but we took a chance and grabbed it too. Got the brake and the Diacro for 2000 bucks. When we got the stuff back to the shop I found a loose fitting on the pressure side of the hydraulics, tightened it up and the thing has worked like a charm ever since...:D

You say finger brake but picture a press brake, which one?

The swag kit looks to be a piece of angle iron and a piece of A36 flat bar. These are not ideal materials for a real press brake. You can buy actual press brake dies on ebay and make your own just as easily.

I made a couple of press brake calculators in Excel that I've been meaning to clean up and put in PDF form. I'll try to get that done soon and post it to the forum.

One is a tonnage calculator, and one is for calculating how to bump a radius.

The one in the pic can be used as a single full-length brake or a finger brake for small pans etc limited to length and thickness of the material...
but it is the limitations which make it pricy for what it is... and making your own would be far more cost-effective... and if you are not worried about prestige super accurate bends then you don't even need a lathe or mill to make one.
