I'm finishing one up currently,It's backed with hickory 1/32" thick. I needed a short bow for my blind for turkeys.Made it from a 4" diameter sapling. I put Copperhead over the hickory. It's 54", 1 and 3/8" wide to 1/2" tips. 52#@27". It took 1 and 1/2" set. Shoots quick,I hope it doesn't fret!! I'll post some pictures of it when I'm done.
