Another Build Thread - My '32

[J. Robinson]

To fabricate the radius rods I need some threaded bungs to insert into the tubing, but I have never found any 1/2 inch threaded bungs. The logical solution is to make my own. I found these "coupling nuts" at the local hardware store several years ago and have used them on the last half-dozen chassis I've built. They are designed to link pieces of threaded rod together, are available in a bunch of different sizes and threads, and they proved to be the solution to my problem...

I made a 1/2-20 threaded stud by simply cutting the head off of a 1/2-20 x 2 1/2 inch bolt. I ran a nut up to the end of the threads leaving the unthreaded part accessible. I stick this assembly in my drill press, thread a coupling nut onto it, and now I can spin the nut while I grind it to fit inside my tubing. Just a couple of minutes per piece and I have my threaded bungs.
