Hey Guys,
I had made a warf-type bow out of a provantage riser a couple years ago. The challenge was that there is a crossbolt that the limb bolt runs through that is movable. It allows the limb bolt to maintain a perpendicular angle on the washer to the limb surface. Neat design, but something has to prevent lateral movement on the limb bolt. A couple years ago, I had just epoxied the crossbolt into one position, but that eliminated the neat feature I described above.
Well, I have a friend that is the manager of a custom fabrication shop, and I approached him with what I wanted to do. Together, we came up with an idea. He took measurements and made me some new plates for the ILF to fit into the pockets. Next, he drilled and taped the crossbolts so that they can be captured in the riser, yet still be moveable for the feature they were designed for. In addition, the crossbolts now allow a set screw to hold the limb bolt in a fixed position to prevent them from backing out when unstrung.
Here are some pictures. The design works out neat. Feel free to use it.
