After tempering it, the draw weight will go up. I tiller the bow to the draw weight I want first, or even a little under, then heat it. I then re-tiller it back down to the draw weight I want, then finish it the same as any other bow. The belly will be darker with a scorched look to it permanently unless you remove a massive amount of wood from it, in which case you will have gone through the wood that was tempered and will have to do it again. I've never posted any pictures, but if you're still interested, I could take a few of what I'm talking about.
