I have to comment on the aluminum .vs. steel topic. In the case of our KR aircraft, the metal only protects the fireproofing Fibrefrax material behind it. Someone else commented this topic is covered in the Bingellis books. Seems to me others in our community have built this way also.
I have samples of all the materials in my remnants pile. Perhaps I can get my neighbor to fire up his torch this weekend and give this a try. Anyone make a reference as to what heat level/ temprature and duration is "approved" as a test?

Any local sheet metal place should have it also. I got a 4' X 8' sheet of I think .016" when I redid my Sonerai and Starduster firewalls. I think it was something like $30. Aluminum will not block a fuel fire for very long. All aluminum planes have stainless or galvanized firewalls. And now that I look, Spruce sells a 3' X 2' piece of .016 stainless for only $35. _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
