In an effort to keep some lively discussion up around here I want yall's views of something I'll be using on the CAD/CAM bass. I have at my disposal an almost obscene amount of aluminum that I intend to use for some parts of the new project. One area that will definitely get aluminum is the nut. The alloy that I have a lot of is an aircraft grade, very hard mixture call 6061 with a T6 hardness. Aluminum in this grade has the characteristic being very hard compared to say, pie pan alloy, but maintains the maleability required to be easy working. As a nut material, I think that it is perfectly suitable and will combine many advantages of the "harder to work" materials: Easy to carve, shape, and polish, high density, excellent resistance to abrasion by the strings, non-magnetic, nearly the same color as all of the other hardware, and CHEEP!! Thoughts?
