Twisting tubes

Recommended Posts

We twist tubes using a greased polished hard 420s/s mandril inside of tubes and pull it out after with a pneumatic piston as it gets quite tight during twisting. To create the ring effect we have modified a large pip[e cutter with "rounded wheels" and release one chuck so that the pipe can spin freely.
I hope this is of interest and of use to some!


ps. our Homemade Twister twists 6meter lengths of up to 36mm solid bar "cold" and 1meter of 50mm bar "cold"
