Pat B, I put the same amount of sinew all the way through from one limb to the other. Does that make a difference?  One of these days I hope to do a sinew up like yours. 
Wow. A sinew backed osage recurve  selfbow for your first build. Very ambitious. I sure hope you're going to let your sinew job cure for a good while before you start tillering. Also, you could remove a massive amount off your tips... they're hugely overbuilt. 
Adb, I have had second thoughts about it at different stages as well, your right it is a big project for my first. I do plan on letting it cure for quite some time, not sure how long is long enough? At least a couple week's?  
My tips are from the end of the fade to the tip 1" to 3/8" , they are static reflexes. Could you explain the over built part to me a little?  
Zenart, thanks. I have looked at that a couple of times. It's pretty awesome! One day I hope!
I have been taking my time working on my bow taking time to read everything, asking questions to an Indian friend of mine who has also told me several times that I should have made a flat bow. I have always been the one to step into deep water first then wade the shallows later.
