I want to put a mahogany and walnut (or maybe phenolic) overlay on a 72" r/d osage belly, bamboo backed longbow. The overlay will be the width of the riser and run roughly 10", from fade-tip to fade-tip. The problem is that there is a node on the bamboo backing almost in the middle of the bow, just in the middle of where I want to put the overlay. (Coincidentally, there's also a node about 1" from one of the tips, where I'll also be putting an overlay for the nocks.)
I know that sanding down a node on a bamboo backing is taboo. My question is whether I would weaken anything by flattening the node where I intend to glue on the overlay(s)? The bow won't be bending at the riser, and I figure the entire area will be reinforced by the handle below and the overlay above, so my best guess is, what the heck. I figure that it will be fine to sand down the other troublesome node near the bow tip with veneers of ipe, mahogany and phenolic for the nocks covering the flattened node. I'm more worried about the node over the riser.
I considered carving a groove on the bottom part of the overlay to account for the node, but it would make the glue line look funky and the node, of course, isn't perfectly straight so the tolerances would be tricky. I'd appreciate any thoughts. Thanks
