Hi, Dear friends I'm glad to present you my new experimental sinew backed bow that I made in 23 days.
The wood is pretty dense (Prunus divaricata Ledeb) or as we call it in Kazakh language ("Alysha") or in many other Turkic languages too. This is a native wood for Tien-Shan mountains & Caucas. I've never heard before that someone had experience with this type of wood for bowmaking. Most commonly its fruits uses for making tasty jams. There is some sources in I-net saying that this wood is pretty dense ( can vary from 0,70 to 0,80 gr/cm3.)
This bow is a quickly made 135 cm ntn has some reflex on the end. No steam bend were used for making reflex just simply freshly cut wood tie with the clamps (see the pics). I cut it in February & seasoned it for almost 3 months . I put the sinew on it (2 layers of horse sinew) And a mix of hide/fish glue were used also.
And for water proofing I used birch bark from our mountains & shellak.
