I need 2” oval DOM tubing in 5 foot lengths, .093 minimum wall thickness. How could I get this shape using round DOM? Would it be better to buy as oval? I would imagine it’s more expensive and this could turn into a repeat job with fairly large quantities.

Drag race guys use some of this for dragster frames, though not necessarily that big. There is a company in Indianapolis that makes it.
More likely to be seamless 4130.
This is less "oval" than a little "pointy" on both ends.
Then there is aircraft streamline tube, always thin wall and very expensive.

I have made 3 foot lengths of 1.125 and 1.25 dia round 4130 into oval by squeezing it between 2 sinple plates in an arbor press, can you do that? I include stops in the fixture, so I can squeeze one end tighter than the other.

I also agree on making your own with the help of a press brake it should be easy. Maybe a local sheetmetal shop can help you out...Bob

The operative word(s) is quantity.
Five feet is not exactly a long length.
I presume that you do not wish to beat up the tube.
Suggest you rig a couple of say 6&1/2 ft wedges, one each with just under the desired inside radius of the oval.
Then while squeezing the tube's flanks, ram the wedges home. They can be rigged to work push-pull. The operation may take on the order of 5-8 seconds.

Check with Dillsburg Aeroplane Works in Pennsylvania...hope I spelled that right. They're known for supplying chrome-moly tubing to people who build experimental aircraft, motorcycle frames, etc. Not sure if they can help, but it's worth a try....

Search at www.thomasnet.com on "tube forming" and "oval tubing". There are over 1,200 companies in the Tube Fabricating & Bending Services category.

Dofasco Tube might be worth contacting. They make DOM and also lots of shapes of welded tube (according to their website). They are headquartered in Ontario, but have US offices.
