Its not due to the foots Tuff its the bad arrow flight! I have done the same with cedar unfletched and have seen it happen with other woods, not always cedar, but always with bad arrow flight or a bad backstop or both.
Chad figure your FOC with these, then look at point weights. From what I figure I am in the same boat as broker to a certain degree.
Also another thing most dont realize, a considerable heavier shaft shot out of the same bow, of the same spine, is going to
act STIFFER then a typical lighter cedar or sitka spruce......the difference betwen Static and Dynamic Spine.
I am working on some foots, acutally took some apart today from the pre 1940's era, foots with a little twist thrown in that if you didnt read the old books or take one apart, you'd may have possibly thought of it, but didnt realize it was long ago in use, or never thought of it at all which would be more then likely the case. I have to say these are the smoothest foots I have seen yet! The uniformity and roundness would make you think they were painted, not two seperate pieces. Not to mention appx 60+ years old, they are still straighter then most wood arrows that I have seen today, both made by big name arrow buisness's or shafts both purchased or made! the paint shows its age (and use to a certain degree) but one needent look hard to see the exactness in cresting from arrow to arrow.
Before I get to far ahead of myself I have a local cue buildier (fairly well known on the billiards scene) who is willing to take some time to show me the tricks of the billiard cue making trade which correlate greatly to the footing trade as far as construction! Now if I could just fine a 1k grain electric grain scale for a decent price.........oh and someone to pawn off 3 gallons of worthless gasket lacquer on, bless there sole, I'd be set! <img src=icon_smile_wink.gif border=0 align=middle>! The garage is set up just clustered with my strip canoe still in progress from last year taking a "curing" rest from summer hehe, and some of the maintence mans gear that needs to be moved. Go figure he'd bring in an industrial grade table saw, band saw, and ossiclating sander and put it right in front my my dang target! So many things to do, so little time! I'll keep ya posted but figure its going to be some time before I come to conclusions that I am sure are no different that things found 60 years ago!
