Marc, I have a technical question.
I have a lot of elm, both American and Winged, and I’ve had several failures with cracks across the knots. For the most part, I just remove the bark layers and use the wood surface for the back of the bow. This works fine if the knots are pin knots or rather small (less than 1/8” wide).
From your “Elm ALB” post, I copied the picture of the knots on the back of the upper limb and enlarged the image to about 300X. It looks like you reinforced the areas around the knots with one, maybe two, growth rings. Is that because the knots are so large, or do you typically leave extra wood for knots on elm?
BTW, you did a great job getting that section of the limb to bend with an even arc…I haven’t been that successful.
Thanks, H
