A simple but useful device that really facilitates the work of the master. Cold forging 

Friends will do useful device for a penny from scraps, shaped tubes, which really facilitates the work of the master in the manufacture of certain forged parts or steel structures with profile tube, as well as illustrate how easy to use it in the process. It will take a few minutes of time and almost no material investment to make it, and I will work with it much faster than without it. So do yourself such a device, I think it will definitely be useful to you.
