-Tim - The cotton string is a small diameter 4 ply cheapo stuff from the knitting section of wally world. Not very strong stuff so had to be careful to stretch it tight but not break it while wrapping. Coated with tite bond 3 three times to hopefully keep water out.
Just came in from shooting some more arrows in the backyard, typical of the bows I make it is not a speed demon by any stretch
but it is fun to shoot none the less.
Thanks again to all for the compliments, much appreciated.
