Pipe frame owner.... Whats under you subfloor?

We are working on a 1947 liner and built a new frame for it. We recently pulled the shell off the old frame. Here is what we found. Its scary to think I towed it home and to a rally but it seemed pretty sold. We have two other pipe frame Airstreams to restore and I know the frames on those two are far worse then this one.

I have a local shop build them. I bought an AutoCAD file form a guy and then we tweaked the design with the shop. They cut the metal with a water jet and welded it up on a jig. It then went to a powder coating shop . I had two built and how we have everything in place to build more as needed.

The pipe frame is in rough condition. MrRivet knows there is one point of an almost complete rust through. Will know full extent of its condition soon when we do the shell transfer to the new frame. Iím sure at that point we will realize that maybe we should not have towed her home when the purchase was made. LOL

That looks very familiar. Itís a great picture of how the ribs where secured to the frame. They just bent brackets out of aluminum sheet and pounded a type of twisted shank spike in to hold it. Itís amazing how well it held up for 70 years!
Good luck with the project.

Wow! Im glad i found this thread Sprouty. I'm building a '49 TW chassis and intent do do something similar. I'll make cross members much the same as original but in steel, and run a pair of 4x2"s right through as you've done, but I'll keep the full length of 4" pipe as well.
I like the way you've tapered the ends of the RHS to stay away from the belly pan.
Thanks,
Stu

We are restoring a 1948 Liner and this is what we ended up doing. It gave us the ability to add A 30 gallon Fresh tank and two 16 gallon connected tanks for grey water storage. We used 2x6 tubing and channel to keep the visual depth to the belly pan. Once it was wrapped with aluminum it has the appearance of a pipe frame.
Safe Travels!!

Thanks Tim, I've been watching your thread and will be referring to it when it comes to belly pan time...
