Here is the finished project that I have been posting about. This bow went from sapling to shooter in under 2 months total, made possible by the arid climate of the high plains.
She is 43" long and pulling 55# @ 25" draw (I expect her to put on some weight over time). Bowstring is 2-ply elk backstrap. Backed with 2 layers of sinew and wrapped with sinew at the tips, mid-limb, and handle. Sinew wrappings were then painted with red ochre and charcoal/pitch.
Thanks for looking!
