The Aircraft Spruce & Specialty catalog has three pages of definitions and characteristics for aluminum alloy. More than you will ever need to know for building a KR Aircraft. If all else fails, read the directions (in the plans). Sid Wood, KR-2 N6242 Mechanicsville, MD sidney.w...@titan.com

What about marine grade aluminum? I have a friend in the aluminum boat building business. I can get virtually any size/configuration metal from him. Is it acceptable? How is T-5 or T-6 different? Are we just talking thicknesses? Some kind of core inner strength? Ray A long **^&%$^*& way from being finished.

My father gave me a name of a supplier.( can't locate name at this time) I called and spoke to him. He does not have T5. OK what to do? MARK, what did you use if you did not find T5. I will need to make the horns but using Dr. Deans method of hinges.< Just use T-6, it's stronger anyway. Not sure why anybody would specify T5, when T6 is more plentiful and stronger in utimate and yield anyway. Are you sure you're not thinking of T651? That's pretty much the same thing as T6, as I recall. I used T6, and most other folks probably did too, whether they knew it or not.
