Classy looking! Why the additional black lam on top of the red?
I like to use 3 layers of phenolic under the wood for both looks and structural reasons. Without that second black layer the string puts more pressure on the wood, and more importantly puts more pressure on the glue line itself from wood to phenolic. The phenolic to phenolic bond is much stronger than wood to phenolic.
It also serves another purpose…. When shaping these tip overlays with a solid piece of material it is real easy to get the shape and depth of the groove off center a bit. You want a perfect tear drop shape. Using different colored phenolic you can see the shape and depth you are filing just by looking at it. This really helps in consistency of the finished product.
Years ago when I was into a lot of performance testing, I did some tests using different thickness and different types of tip overlay material to see how it effected the speed…..On hunting weight bows I found very little difference between a solid G10 overlay, and lighter weight wood overlays as long as I kept them moderate in length. I even taped nickels to the tips one time to add tip weight, and didn’t see a big difference at all….Some… but not a lot. Kirk
