First, I'm only talking about tension piecescroman74 wrote:I just want to make sure i'm understanding this right. Are you saying that if you were using say a 1/8 x 1/8 piece, it would be lighter and stronger to use a 3/16 x 1/16?

Second, I'm saying that 1/64th paired strips are significantly lighter than any reasonable square cross-section stock; for instance, if you're using 1/8 x 1/8 for other (compression-loaded and coulmn bracing pieces, the comparison would be against 1/8 x 1/8 for tension pieces. Don't follow your 3/16 x 1/16 math

If you cut a piece of 1/8 square to 1/16th, you have 1/4 x 1/16th = 1/2 x 1/32 = 1/64th x 1"

Specifics from spreadsheet on densities and tensile strengths by cross-sections- pieces able to carry a 12kg tensile load;

1/8 x 1/8; about 5#/cubic foot = 0.009 gr/cm x 30 cm x 2 per sides x 2 sides = 1.08 gr

1/64th x 1/4- at about 14 #/cf = 0.0055 gr/cm = 0.66 gr

About 0.4 gr lighter; not a lot in total amount, but percent-wise>33%, and 0.4g is....0.4 gr

What makes the effect even greater is that lower density tehds to have more variability/imperfections, so the theiretical tensile for light 1/8 square is.....less likely to actually be there, so to be safe, you have to bump up to a higher density.
