I wrote, " . . . neck blocks and heel blocks are usually made with the grain running top-to-back."
To which murrmack123 responded, "And what evidence do you have for that assertion ?"
I only have evidence, and not proof, so maybe I should have written "sometimes" instead of "usually."
I wrote "usually" because my personal experience in inspecting and building guitars was reinforced by graphics at:

as well as pictures and text in books by Cumpiano, Gore/Gilet, and Somogyi.
But that's only evidence, not proof.
You certainly may disagree.
