Here you go, Chris. Laying out the boo with my bow pattern. Every piece of boo is different, the nodes will be spaced differently, you want the end with the nodes closer together to be the bottom limb. I strive to have a node equally spaced at the end of the flares, you will notice there is a 6 " mark on my pattern, that is actually about 8" from my flares. My flares are 1 1/4 wide and I hold that 1 1/4 width out for another 6" to beef up that area of the limb. From that 6" line, I do a straight taper to 1/2 wide at the tips.
Once I flatten the belly side of the boo, I lay the boo with the flat side up and mark the center of the handle according to how I had it laid out in the above picture.
Then I clamp my pattern onto the boo and align it up. You want the center of the limb tip to be on the high center crown of the boo. Those long black lines on the ends of the boo are the peak " center " of the boo's crown. Sometimes you have to slide the pattern to one side or the other to get a nice alignment. Notice how close the pattern is to the right side edge of the boo. After the pattern is traced out onto the boo, I cut it out, staying about 1/16th away from my line. Those areas where the boo is very thin on the edge of the traced pattern, I stay away from when cutting out on the band saw, boo is brittle when it's that thin and close to the edge, the band saw will tear it out. Ask me how I know?
After the boo is cut to the shape of my bow, I use a palm sander to get "to" the line, but leave the line. And with the palm sander is when I address those thin edges.
Video of sanding to the line, little hard to sand and video but you will see how it's done. Remember to go to the line, don't remove the line, but sometimes a Coors light will make the sander slip but it's no biggie:)
After the boo is cut to bow shape and sanded to the line, it needs thickness tapered from about 1/8 thick at handle to 1/16th thick a tips. I use a sander and the a toothing plane to do that. You want the belly side of the boo to be nice and flat and uniform.
