Simple manual bar ring bending machine

Connecting steel rings are usually much more expensive than the bar they are made from. In this regard, in order to save money, it is better to make such products with your own hands. This requires a simple ring bender.

Materials:

  • Strip 50 mm;
  • pipe 50 mm;
  • pipe 32 mm;
  • round timber 20 mm;
  • nuts М8 – 2 pcs.

Machine manufacturing process

We need a strip and a pipe with a diameter of 50 mm and a length of 25-30 cm. They need to be folded together, aligned at the ends, and welded.

Next, we saw off a 32 mm tube and 20 mm round timber 40 cm long. An M8 nut is welded to one edge of the round timber, and a segment of the same rod is welded to the second at a right angle.

We weld an M8 nut to a small section of the strip. Then we find a concreted post on the site or dig it in separately, and weld the first and last blanks to it as in the photo. A right angle must be observed between them. Moreover, the strip with the nut should be slightly below the center of the pipe.

Now we place a previously prepared workpiece from a 32 mm tube into the welded pipe. We take a rod of 4-8 mm, and we twist a hook at its end. After that, we pass the rod through the nut on the machine, and hook it up with a round timber handle.
