The A65 frame has areas of the tubing reinforced with inner tubing. I'm not really sure if this is done for strength, which of course makes sense, or maybe alignment while manufacturing? It's not every where, and in some places seems unnecessary, at least to me............. Also, I was amazed at how much RUST there was inside places that didn't seem open to the elements. Here's a few photos.

AIUI the extra tube in the lower rear of the cradle is to help prevent the tubes from bending/kinking during manufacture. Never realised it was in other sections also.

The last picture, I assume is what you referred to in your pm?

Allan, Yes. It was my intent the shock mount would positive locate. Not as positive, but I could cut it off between the seat mount tab and the shock. The bit of flat gusset still remaining would help with the "rotational locate".

That sounds like a plan KC.

The Experimental Aircraft Association magazine has ads for products that aid in building your own aircraft.

One of those products is a type of oiiy foam that can be injected into fuselage tubes to prevent internal rusting.

It might be a good idea to use this when restoring an old frame.

My focus on the inner tube pieces was this: How do you get them in to the frame tubes? It must be a very "fiddley" process. How can a production line fool around with that? I guess there were many Hands-On steps in manufacturing at the time. Folks had specialties. Watching some of the old factory movies shows that. It was just interesting to see when cutting.
