If you're new to the game you can't go wrong with the link Bubby gave you. Try that one first . Like I said, the bow you have was really pushing the limits of design. That's what it's all about though , and if the bowyer was into flight shooting ,that explains a lot. After you build a few ,then start to tinker with design a bit at a time. If you throw a whole bunch of new ideas on a bow at one time , and it fails ,you might not know what the true cause was , or if it was a culmination of many flaws.
The design of the bow is a good one. I build most of my bows with stiff tips and a stiff handle. You just have to be sure that there is enough working wood to handle your draw length . If stiff tips are kept to about 5-6 " with a little more bending towards the tips than what your bow was doing, you can optimise the lever action you are looking for while keeping the tips light. This reduces hand shock. It also makes more of the working limb share the load instead of putting the lions share towards the handle. If you need more draw length you can make the handle section shorter. (depending on how you hold the bow) or you could add overall length to the bow. Remember though , there is a very fine line between high performance and durability.
These are just a few suggestions for that design but "there's many paths up the mountain". good luck!
Thanks for the link ,Bubby.
