a buddy and I cut a hickory sapling (from where we hunt together= Good Medicine I hope) a few months ago, split the two logs into six or seven staves, one of which I grabbed on a recent trip to his house. I plan on leaving it the 70" or so that it is and it's 1-1/4" wide through the handle section.
never having made such a long bow I'm not sure if a D tiller would be the best...seems that leaving the middle third a bit stiffer would probably be best,, but that's only a guess on my part.
any suggestions ?? and pics of such a bow would be great.
