Sheet metal bending brake.

[Tuomas]

This is my bending brake.

I made it from 4mm thick 40 x 40mm L-profile

6 and 12mm steel bars.

And 3, 4 and 6 mm thick flat bars.

This short video shows my space saving idea in it:

I wanted to get brake that could bend 2-3mm thick steel. Also i wanted to be able to do some bends with bigger radius, without noticeable marks. That's why i made bending radius adjustable.
This video shows the actual making the frame:

You can see the main idea of the structure and the radius adjustment from these pictures.



I bought hinges, screws and nuts from my local hw-store. Those costed 5 euros.

All other material is from the recycling center and costed 30 euros.

Used tig for welding, but it could be done with mma, mig/mag too, of course.

Closer look for the "corners" little groove allows to make brackets and stuff like that.





I like to use tig, it doesn't make splatters. Build was very simple process, all parts are cut straight.
I used chop saw and angle grinder for cutting. But that's optional.

Drill press and hand drill.

M6 threading tap. M12 threaded rod. M6 nuts and bolts.

2 pieces of tight springs. Washers.

Finished my bending brake.

Now it has a easy to use radius adjustment from 1-12mm:

Tuomas,

By coincidence, yesterday I built a folder and many features are similar to some of yours, even down to the bend radius adjustment.
Good work.

Thanks. Now we both can be sure that idea can't be bad, if two persons ends for the similar solution.

Forgot to add pictures from this simple feature.




Allows me to bend brackets and stuff like that.
