bradsmith2010:
ok this next bow I take you way back in time to a humid 100 degree time in Texas 1999 bow,, when peopel say sinew is no good in hot humid,, its just not true,
the bow is 52 inches nock to nock,,
first test temp 100,,sinew applied july 24, aug 10th test,, bow pulling 55@24,,500 grain arrow 170 fps,, and 380 grain arrow 187 fps,,
ok as you can imagine the sinew is gonna cure more, and I have more notes on that to come,,this is with B 50 string, I dont think I even knew what fast flight was back then,, ;D
StickMark:
Brad I just put that 460 grain arrow into that formula....formula said 460,
so "good intuition" on that :D

I have a sinew backed hide glue black locust bow that is 48 lbs, at 24 inches of draw, and 52 inches long.. The strongest, and fastest short bow that I have built to date. I can't get it to full draw now, but back when I could I shot 430 gr arrows at 160 fps with a 10 strand B55 string. It was a bear to pull to full draw, so I gave up on heavy poundage short bows, but I have built dozens of short bows in the 20 to 40 lb class. Jim Hamm claims the Pawnee built 45 to 50 inch long Osage bows that were up to 70 lb draw bows, and that they could have been Olympic weight lifters. That would have been way to much for me even on my best day as a young man.

thanks guys let me organize my notes and more to come,, I wish I had been more detailed at the time,, but at least I have some notes and some things make sense,, and some patterns emerge,, even after 20 years,,

Brad most native Indian people where pretty short so I can also understand them having shorter draws. And shooting from a horse of course the draw was shorter , faster, and more demanding. Them guys where bad asses.
