Nice write up! I would ad that when making bungs and threaded slugs, Try to get 1018 cold rolled steel, It threads much better than hot rolled. Also many sizes of dom tubing are avalable with the i.d. the correct tap hole size

DOM tubing is very nice material, but kinda pricy for cutting up for bungs especially if you need thick wall and have to meet a suppliers min purchase (often a 20' length of each size) Horton also has what he calls weld nuts that are inexpensive on pg 53 of his downloadable catalog that would be good to use instead of a welded on hex nut:

I buy most of my dom tubing on line, Speedy metals sells it by the inch and several others sell it by the foot. Some of it is very pricey but if if you do not have to drill it you save lots of time and trouble.

Ax, you are not only well versed in fabrication and truck restoration, but you have a great command of the English language. I think I installed a couple of bungs, or spacers in my winch install last week. Part of my winch mount was bolted through square tubing, so I cut some 1/2" black pipe and drove them inside to keep it from collapsing. I didn't know they had a name. Hey, maybe they were crush tubes. .....

I guess I'm a resto-mod fan

Note, when I took the picture, I hadn't yet finish welded the forward bung. It was just tacked.

Hope I'm not junking up your thread with my pictures / posts.

Doug, good real world example pix are always welcomed by me! Nice examples of use of bungs, additional source link and also of clean full penetration MIG welds. I like the way you modified the bung for the angled install and how a bung is used to allow for that install. Thx!
