Cut 1.5" off each end. Those levers aren't doing anything anywho. The only way to start building bows that hit your weight is to start pulling them farther sooner, providing your not hinged up anywhere. You cant be scared to bend a bow while tillering. If you tinker around with a long string and never put anymore than 20-25# of pull on the bow you will end up with a rack full of 40 pounders. Get the tiller closer earlier and brace when you can. Forget about the thickness of the limbs, its irrelevant. .
I llike to low brace as soon as I can physically make it happen, ask the guys that worked with me last weekend at MartyJam. They think Im crazy, for many reasons of course, but I like my bows and will keep early low bracing them. It allows me to get any weight I want. So what if I take an extra 1/8" of set because I braced it at 75-80# and want a 55-60# bow in the end. Most all that belly wood will be gone by the time I get down to my target weight anyway. When I say low braced, Im mean 1-3" max.
