The Jigs …

As the metalwork would surely entail a certain amount of bending and curving it was considered essential to provide some sort of reliable metal shaping gadget and this was the end result…crude but proved very useful.

This jig was made out of bits and pieces of leftover channel and three roller bearings. A section of tubing was welded to the central one to allow for a “handle” to be attached. The jack handle controlled the bending force and the round bar with the black knob attached was linked to the release valve . Although ideally best suited for bending round bars, it managed to  do the trick with flat bars too, requiring a little patience and frequent realignment  of the bar being fed to prevent slipping and/or warping. 

The bending force was provided by a car jack I had lying around.
