looking for source for 4130 flat-oval tubing
hi guys --
can anyone tell me whether such a thing exists at flat-oval 4130 tubing (that tubing shape's also known as "rectangular-oval" or "floval")? i know it exists in alum, because bmx company se racing has been using it for decades in their "pk ripper" frames.
i've done a lot of looking for that same stuff in chrome moly, but have come up empty so far.
I heard about one company that uses that material in their bikes and makes it in house from round 4130 tubing. I thought it might be possible just to run it through a rolling mill. I want to make a mill, but it's not high on my projects list yet. They are pretty cheap to make if you have access to a lathe.

I think Trek bmx bikes used them on the TR series in the late '90s. They may have made it themselves. I don't know for sure. I think tubing manufacturers will make it for you if your order is big enough.
