Let’s build something crazy! Ash Wing Bow (EXPLODED)
RyanY:
I want to mention that I have crowned the back of several board bows. This is primarily for aesthetics. Theoretically I think it operates similarly to trapping and could help in compression. This would be good for this bow considering the curly grain. I also wonder if adding a crown may help get away with some level of grain runoff due to the curved surface as it seems many breaks along the grain must start at the edge where it runs out of the limb. This would help the edges experience less tension.
The chamfers on the belly will certainly concentrate the compression strain to a degree but this bow is built more for aesthetics than performance. I will consider it a failure if I get compression fractures though. Still needs to be a bow!
RyanY:
Finished the 'airfoil' limb profile. Certainly not the shape needed for lift but something that would feel interesting and help thin out the trailing edge. It's hard to take a picture of the actual limb so I drew a quick sketch of the steps I took to get the shape. Now it's time to draw the "feathers" on the limb and start cutting them out. In retrospect I should have waited to round the trailing edge so it would be easier to draw on the limb but no biggie. I'll start by roughing them in and then will get the bow bending before spending all that time shaping and sanding them. Till now the bow has not been braced due to the limb being too wide near the tip for my tillering string. Feels pretty stout still with floor tillering so hopefully I'll have some room to get the bend the way I want it to. Fingers crossed!
Pat B:
Interesting, Ryan. Looking forward to the end results. :OK
Will B:
Very cool build! Thanks for the detailed description of your build and the step-by-step photos. If it can be done your the guy to do it. Good luck
