I've been thinking about alternative riser layouts and designs for my lam bow. While the first one eventually worked out, I wasn't really happy with the force required to get the belly lams into place, even after pre-forming them with steam. I learned a bunch in the first attempt and am sure I could get things to go more smoothly on a second run but I would prefer to design a better riser layout to eliminate the issues from the start.
I have been thinking that a riser more like Kenny's last FHLB would make more sense in that it lets me use larger radius bends for the belly lams, which should ease the glue up forces.
In the attached sketch my first riser is shown on the right with the FHLB styled riser on the left. In both sketches the belly and back lams are hatched to highlight them. The sketches are accurately drawn to scale, so all proportions are correct.
Let me know what you all think about the alternative design as compared to the first one.
Thanks,
Mark
