That looks fantastic chuck, love it
Figured it up here in grains for sinew you used.Close to 1800.Is that including the wrappings on the handle too?That must end up to thickness wise being a good 1/4" thick for sure then dried.How wide did your bow end up too?
I used 1000 grains on my latest composite over a 48" length and it ended up a strong 5/32" thick on 1and1/4" wide@ fades limbs.I too use elk leg sinew mostly using my longest ones for the last course.Around 20" long I guess.
