Dave, that's a pretty good idea! I'm curious to see how thin the wooden lams would have to be to flew properly, but that sure would look neat too!
Right now I'm thinking I went a bit far with the egg shape. If the purpose of the leather is just to cushion the bend, then the handle would only need to be radiused enough to fit along the belly of the bow at full draw, with any extra radiusing being a bit of a waste. I'm working on a couple D bows now that I might put a handle on, dpepending on how they turn out. If I do, I'll give this a try on one.
