This may seem dumb, but I have never heat treated or tempered a belly of a bow. How do you heat treat and is it the same as tempering? And if not what is tempering and how do you do this?

If you have (or are thinking about getting) a copy of the new TBB vol 4, there is an excellent & comprehensive chapter by Marc St Louis on this very subject. This chapter alone is worth the price of the book. It can be purchased at horsefeathersranch.com.

I made an Ash bow last week. It took more set right away than I wanted to see. So, before any finishing , I brought it home and sort of levered it over the kitchen island with the other end under the dishwasher and "toasted" it with my heatgun. I had some REVERSE STRINGFOLLOW sprung into it while I worked. (Note: all the aformentioned appliances plug into my Pre-Columbian 120V outlet in the kitchen)
It browned it up a little. It seemed to lift the grain a little. I took it back to work the next day, final sanded it and doped it up real good with my oil mix. After that, I thing the pull is about the same, but the "set" has not returned to it's previous level.
In retrospect, I probably should have toasted it longer, and let the heat get to the middle. And, a simple clamping system might have saved me standing there and holding it till bedtime.

I do just as Pete C does. And yes, they are the same thing, tempeirng and heat treating.
