Here is going to be my attempt for this challenge.
The second bow shown here, a sinew backed hickory bow from " North American bows, arrows, and quivers"
now I don't have any hickory so I'm going to use HHB. I'm also going to make it longer than the original so that I can have my normal draw length, original was 3' 5"/41" my stave is 4' 2"/50"
so far I have about 30min of work into it all done so far with the knife in the pics with it
current Sizes are about 1 1/2" wide and around 1" thick give or take, it started about twice that size.
