CMP tail gate hinges

[Grant Bowker]

The jig was in the vice. I preheated the hinge stock before inserting it as you described. My thought was that I would limit the heat getting into the jig to reduce distortions. Most hinges took a second heating.
The jig rod was the same size as the hinge rods but to ensure a bit of clearance I did run a 33/64" drill down the barrel of the freshly made hinges. some didn't need any material removed, some did.
