ive been waiting to see someone do this with glass....i have made a lot of lever selfbows...im not a glass guy but i m sure you can narrow those levers down more and shorten up the fade area so its not such a long transition...thats if optimum performance is your goal. it looks like you used osage out in the levers?? i wouldve used a much lighter wood like a spruce,cedar,or even something like a maple. youd be surprised how small you can go with levers as long as everything is lined up perfect(even with selfbows,and im sure you can even go less with glass)...i can go 1/4" wide along the whole tip overlay then tapering to 5/8" ten and a half inches where it meets the 1 1/2" long fade(12" long total lever).and my thickness starts at 9/16" at the fade to the lever and tapers to 7/16" right at the start of the tip overlay. this is with an osage selfbow
ill be a watching
