Ray, If you kill something with that and a homemade arrow your going to get props from me for life 

My son and I just did one for him, but we screwed up a lot of stuff. Looks like you are really making the extra effort to do things right. I always get in a hurry when I do projects like this. We sinew backed his, and I added antler to the tips, and an antler arrow rest. Looks nice on the wall, but not as functional as I would like. Also, we made it for my 10 year old, and he can't pull it to full draw.
Can't wait to see your finished product!
