To make the hinge I needed to bend some 1/2 inch tubing. I wanted them to be all the same. I have a diacro hand bender but no 1/2 inch die with 3 1/2 center radius. I turned a blank on the lathe and finished it in the mill on a rotary table I also made a follow bar.
Here they are with a tube blank mounted on the bender
Tubing blanks all bent and they all came out nice
Next Imade a jig from scrap to cut them all to the same length
The same jig in the mill to cope the other end
Another jig made from scrap to hold the end tube for welding
Here it is all ready to weld.
Thats all for now .......... Mark
