Anyone know of a place that has 1 5/8 OD x .134 wall Mild Steel Tubing in stock? (preferably in So-Cal) (Also 1 1/2 OD)
Please don't tell me Industrial Metals because they don't stock it.
regards,
Max Blast

Max,
Call Tuch Metals in Northridge, 818-349-3761. The last time we bought raw stock, we got it from Porterville. It was about a third less than local suppliers.

But why .134 wall??? Just get .125 DOM (Drawn over mandrell) it comes out to a little over the required .118 by NHRA Not only that, You save a whole bunch of weight... Just tell them to Mic it first for the correct wall thickness...

The problem with the .125 stuff is that the mill tolerances can be +or- .007 or as thin as about .118 which seems OK at first. The problems can come up when you bend the .125 wall tube. The outside of the bend gets even thinner and has been known to "test" out as under .118 wall. Where do you think an over-zealous tech guy will use his sonic wall thickness tester on my cars, you guessed it - the outside of the bends.
The total weight difference due to added wall thickness comes to a little less than 15 lbs maximum. Worth considering but not critical for an index or bracket car.
The .134 wall tube pretty much guarantees passing tech and the biggest downside is the difficulty finding it and at a decent price.
BTW only the tubes with bends in them really need the thicker wall, you could get away with the .125 wall on all the straight pieces.
Anyway, THANKS TO ALL for the great responses, I'll call them all tomorrow to find out who's got what.
regards,
Max Blast

You might be right to an extent. With a true mandrell bender. The outside of the tube does NOT stretch. Like it does when using the old Muffler shop bender. It actuall pulls the tube around the die. A true Mandrell bender doesn't.It rolls the tube around the die. I've used DOM tubing on a few cars, and never failed a cert. test. But like you say, 15lbs?? Who cares....

In the Long Beach Port area there is Phillips steel, Anaheim and the 710 Fwy. I stopped by there this morning for some remnant aluminum stock, very reasonable.

Just a point of clarification, to bend metal, tubing or flat, the metal has shrink and stretch.
It shrinks at the bend die and stretches at the opposite side. At centerline of the tube/sheet, there is no change and that is where the bend length is calculated.
