Thanks, Ken. I have a 1" square piece of wood with a screw in the middle i slide along the belly to find weak and stiff spots. It shows me the same thing you see. I really had to remove a lot of wood on both outer limbs to get them bending??? Thats about all the tillering ive done with this bow other than a flat spot midlimb on the right/top limb. Forgot to mention that the wood is quarter sawn and the back is trapped.
