Duplicating 36 Pontiac bumper bolt

[Bloo]

My 36 Pontiac front bumper is out getting rechromed, so it was time to deal with the missing bolt. Unfortunately it was not a normal bumper bolt. There are not square holes in the bumper, so a modern replacement won't fit. To keep the head from turning, there are only a couple of little bumps that catch in a shallow groove in the bumper. Here is an original.

 

 

So the plan was to drill a hole through the new bolt, and the put it in the lathe and remove the square part. Then, put a pin in the hole.

 

 

Braze the pin in place.

 

 

That made the proper "bumps", but they were too tall, so back into the lathe it went. Here it is after turning the bumps down to the correct height, and cleaning things up a bit with a Dremel tool.

 

 

All that is left is to polish up the stainless skin, which is blued from the heat of brazing.
