hi one more time.
i shorten the limbs and now bow it 72". with this modification it became just above 25#.
then i decided to go further. i have removed denim backing and applied 2 mm beech lam over it. without hemp backing it is know #35 @ 28" it is almost what i desired at the first place.
now, i think i will leave it as it is and do not apply and hemp or backing things.
what do you think about applying one more layer of backing of hemp or something? or do you suggest leave it as it is and make a new one later.
btw: i have used (for this time) epoxy called era4000 (technomarine). glue soaked by the wood nicely so i decided to use a finish material as well.
best.
