Awesome! Thank you so much for this! You nailed this, I hadn't thought about the junction at the siyahs and the limbs being the potential failure point when shooting at lower efficiency, I was only focused on the bending limb being damaged. T bow is a traditional "5 piece" design and was made with 4 total v-joints and the male members are about 4" long into the bending limb secured only with hideglue and an extra wrapping of sinew horizontally over the joint. 2 joints at the junction of the siyah + bending limb, and then 2 joining the limbs to the handle section and the horn + birch core were grooved to increase gluing surface like you spoke about. So the bending is definitely isolated to the midlimb on both limbs since the male v-members act as wedges. The specific inspiration for this was the "Zargalant" or " Jargalant" which was a design in use largely between 200AD - 1300AD with the only difference being mine was made to fit my stature, so it is ~15% larger than the original proportionally. +15% longer tips, +15% longer limbs, +15% longer handle section. 64" NTN vs historical 57" NTN But like you said, the ears are huge - 32cm long including the "Kasan" knee section - and those V-joints are saturated/secured with hide-glue. So I imagine you are right about efficiency being important to protect that joint even moreso than handshock.
@@Couponuser16 Happy to do what I can. What I lack in experience with an actual horn bow I suppose I make up for with being cautious because I have experience with heavy bows exploding.
@@johnjriggsarchery2457 You certainly helped me out, thank you! I was watching your old videos on sinew backed horse bows and figured you were the right person to ask!
