DOM tubing

**RoadRacer** · 03-26-2008, 10:08 PM

Does anyone know where I can get 1.75" x .095" Seamless mild steel (DOM) tubing?

Thanks

I got some from ART today but it was a tad bigger like .120 Give them a try they should have it

ART carries 4130 if you are looking for that

you might also want to check Metal Supermarkets in downtown tampa. I am going to be picking up some 1.75" .120 tomorrow actually for a jig for our axle to be heat treated

that or Alro Metals on 49th street. They will have it for sure.

Thanks for the info, I will try alro and Metal Super Market.
ART doesn't carry DOM.
If I can't find DOM, then I will probably use CroMo from ART.

Thats funny I just bought a nice chunk of it yesterday from ART.

Maybe I bought the rest of it

hmm, I called earlier this week and they said they only sell ERW, not DOM.
I have an ART cage in my car right now, but the new car I am building needs DOM tubing to be legal in order to run with NASA.
I will call ART again. Thanks for the info

how do they know the different anyway betten seam welded and drawn over mandrel especially after its all painted? You sure .095 is legal? Thats pretty thin unless its C/M. The stuff in my bar is .130 and its beefy but ERS

sub'ed for future reference...

I found DOM
Jimmy Cope Racing off of 49th St N in St Pete has .095 DOM, which is usually used in cars up to 3000 lbs. He also has a mandrel bender.

thats cool. So you just buy straight lengths and the bends and weld it all up yourself, right?

Not for most sanctioning bodies. many will will require AT LEAST the main hoop to be of a single unbroken bar bent to fit the confines of the chassis.

you want the LEAST amount of welded in bends as possible. go grab a rule book for any sanctioning body, almost all of them are available online. the rules usually specify a diameter and thickness and number of points for your given class/weight.

Good Luck

**RoadRacer** · 06-06-2008, 10:42 AM

Jeff is right. The main hoop has to be one continuous bar with bends, so you can't weld straight pieces to 90 deg bends. The welds have to be top notch with full penetration. There are many rules to building a legal cage (SCCA and NASA), so get a rule book before you spend the time and money on a cage.

If your car is under 3000 lbs 1.75" x .095 DOM should be fine. If you use ERS the wall will have to be .122 because it isn't as strong as DOM. BUT, SCCA and NASA won't allow an ERS cage to pass tech, unless it was built and accepted into the cars log book before 2003.
If you are going to do any competitive racing, build a DOM cage.

norachelhere · 06-08-2008, 07:10 PM

I knew the main loop had to be one solid piece (i'm assuming with one weld)
I didn't think the rest of it would be a problem....
I'll have to find some rule books and find out... The original idea was to build a cage/chassis for weight and suspension.... but it might as well be legal if we're gonna do the work right?
