Tool developed for bending handrails for the BR 20t Brake Van Project - but obviously its use extends beyond that...

Designed for and tested on 0.8mm diameter stainless steel mig welding wire, that is otherwise rather difficult to get a neat, tight, bend in.

It utilises a modified M5 Hex head bolt, with a plain shank element of at least 20mm, cut and slotted at 1 end 5mm deep - see the .STL, just don't expect a 3d printed version to work! It uses a second bolt (or second part of the first one).

It can be used free hand, but I have also included here the test piece used for the handrails specific to the Brake Van - this could be modified easily enough to other lengths.
