Friday’s Fabrication Series —Tubing

As an engineer, I should know about steel tubing types and their properties, but my course in Strength of Materials in college was in 1962. And while I remember some terms, I needed a refresher course prior to selecting the tubing for my center X-member project. I did my homework on the net and headed over to IMS to purchase some tubing. After looking at all the different terminology on the tags, I thought I should ask some of the workers what each tag meant. For example, ERW, CREW, DOM, Seamless, ASTM513 as well as 1020, 1018 & 1026. I knew they dealt with the process, specifications and carbon content but what did I really need to build a hot rod center X-member. I stopped one worker and he told me to read the tags and let him know what they stated and he would get me an answer. I simply asked again if I needed DOM which is a term used widely in building chassis, roll bars, etc. He told me that he would not select the DOM due to the high cost of the material which concerned me. I know that all the reading I do tells me most builders use DOM tubing which is a process to improve the dimensions to exact specifications, both OD and ID. And improves the tensile strength from 58,000 psi to 80,00 psi — but it is still an electric welded tube that started as a flat strip of metal. The gentleman next to me overheard my conversation and told me that for what I was doing, the CREW (cold rolled electric welded) tubing would be just fine for the application. He suggested 1 1/2 x .120 (11 ga) CREW 102o which they had in stock. I left without purchasing the material as I was unsure of the specifications I needed.

I decided to visit Frantic and see if he knew about tubing before plunking my money down. I had heard he was in a car accident and was O.K. but in lots of discomfort. He was at his shop supervising the employees and looking at his damaged Chevy hardtop. He recommended the same type of tubing as the other gentleman did, so I will go back tomorrow and pick it up. I told him to go home and take some time to recover from his injuries. He agreed. I wish him a speedy recovery.

Take the wife/girlfriend out for Date Night and drive your Hot Rod or Woody!

Stay Tooned!

Looks like a fun way to spend an afternoon cruising in your model 40 roadster.

The 33 is my favorite hiboy roadster. The color and DuVall windshield is what sets this one apart from the norm for these roadsters.

The simple approach to the front end keeps with the overall styling of the roadster.

In second place on my bucket list is a Deuce hiboy sedan such as this one built by Roy for a customer.

I could become interested in one with fenders also. The key to the look on a model 40 is the low stance of the front end sheet metal.

I do like my trucks and moving to a little later year like a BBW 56 really excites me.

He was cruising around El Segundo when I stopped him for a photo. This is a very nice truck with a great stance.

Every garage should have at least one wall hanger of a Deuce. All original parts were used by George to create his masterpiece.

Bob-O wants his old Tub back now that his Mercury has left his fleet.

Tubs are loads of fun and you can carry all of your buddies to Bob’s on Friday night.

Dave had the nicest 36 sedan delivery I have seen in a long time. Needs nothing but a driver.

I love the simplicity of the 40 deluxe coupe done up in Mandarin Maroon and whitewalls.

You can tell how straight this one is by looking at the body panels. Nice!

We can’t purchase this paint legally in CA but this is a very nice maroon for a 40 Ford.

The trees leaves blend nicely with the red Deuce coupe.

  1. A few more drives with the coupe before winter sets in here in Mn. Leaves still on the trees.

  2. After 28 years with PPG the Duracryl can brings back fond memories! That F-100 really is the perfect everyday driver.
