To bend a strip of metal into a ring, you can use a 3-roll mini bending machine, which is easy to do with your own hands. This device is perfect for the home workshop and garage, as it takes up very little space.
For the manufacture of a three-roll mini bending machine, a corner, strip, bearings and other materials will be required. In fact, this homemade product can be made from rubbish, which is more than enough in the workshop and garage.
First of all, the master cuts two pieces from a corner and a strip of metal. Then they need to be welded together, previously fixed with clamps.
The main stages of work
It will be necessary to weld a thick plate to the resulting two parts with two holes drilled in it on the sides. A second steel plate is attached to it in parallel, and bearings are then installed between them.
At the next stage, it is necessary to grind the third roll on the lathe (the author uses bearings as the first two), and weld the mount for it.
And then it remains only to make the missing structural elements, after which you can already proceed to the final assembly. Welds will need to be cleaned with a grinder so that everything looks neat.
