right in the middle of each limb is stiff as a board, and causing hinges just out of the fade and just before the static tip. Don't draw it this far until you've done some serious scraping, and then don't draw any farther than it takes to think you might be imagining that something might be wrong maybe. You might be able to save this bow from taking more than two inches of set if you slow down and do some heat treating.
It's funny, this is almost exactly the opposite of my first tillered board that never became an actual bow. Stiff fades and outer limbs, huge hinges in the middle of the limbs.
