This is a tiny tool, manufacturing marvelous arc sizes from 4,6,8,10mm steelrod, but whoever feel like creating iron rings with it, it's not a big deal. The rolls were bushed and turned from C45 steel. It was important for me, not to place the device in a cage, because if I make a ring then it cannot be taken out. The tool itself can be easily set in a clamp, after one-one squeeze with the help of the turning handle we can roll back and forth the given material. It can be used to make decoration stuff for arcs shaped bracings or even for making strong rings etc.
When purchasing a tube bender we usually get a wide V shape rolling pair, but unfortunatly using it the tube will never get a nice bending arc. In my workshop I can manufacture for you the perfect rolling pair, already bushed, for the right tube diameter. The rolling pair on the photo has a diameter of 80mm, is also 80mm wide, bushed with bearing rolls, made for a 20mm shaft.
I've managed to collect many used spare parts due to my car mechanic pre-life. One night the idea came and I did the first chess-piece. Then the other 2000 spare part pieces came together within a few month. If you have any so-called "crazy-ideas" just let me know !!
