DIY Metal Bending tool for bending of reinforcing steel, rod, round, flat, square bars.

It is very suitable for the making of concrete reinforcement cages.

The bender can do bents using the guides of main unit
at 7-12-17-22-27-32-37-42-47 cm

and with the use of the addition

at 5-10-15-20-25-30-35-40-45 cm

Also it is easy and simple to modified, according to your needs.

The plans are avaliable at (.skp) format at "Plan Files Step"

you will need Google SketchUp8 or any newer to open it.

It is a quick and simple build, made from leftover materials, and most of the needed tools exists at any toolbox.

Here is a video of this build, and the tests of the bends with reinforcement bars and flat bars

I have use a disk saw machine to cutting the piece for the bushing, but if you haven't such tool, isn't critical or prohibitive.

Using your angle grinder, a very simple jig and your bench vise, you can do the cut easily and pretty good. (See Step "Preparation of Bushing / Pivot Set").

Also if you haven't the needed taps for tapping, then you can weld nuts. (You can see the sketch at Step "Plan files")
