Thanks Eric. I back almost everything with sinew and juniper is one of the best woods for that. Cedar bugs live in the bark of juniper. They do not harm the tree until the tree dies, then they go to work on the wood. When you cut juniper it is a good idea to strip the bark to solve this problem. Make sure to seal the ends and the knots so you don't get splits. I have fornd around here Utah juniper has more bark betels than rocky mt juniper. Some juniper will make a nice self bow but most of the time the bow will break after a couple hundred shots. Sinew is the best backing, but rawhide and anything else to help relieve tension on the back works as well. I don't decrown the wood. If I have to remove some of the sapwood I bring it all uniform.
Good luck. I will post a short sinew and juniper so you get an idea of what is possible.
