How to make a bending machine driven by a screwdriver

Hello, dear readers and homemade products!
When making various homemade products and metal structures, it is often required to bend a pipe, strip, bar into an arc or ring. For these purposes, a variety of bending devices and machines are used.
In this article, the author of the YouTube channel “Master Sh” will tell you how he made a small bending machine. The machine shaft will be driven by a screwdriver.
How to make a bending machine driven by a screwdriver This fixture is relatively easy to manufacture, but it will require a small amount of welding work.
