I'd like to echo George's point. I guess I didn't read your initial post well enough. If someone else made this bow it is his work and it should be accepted as such. It is what it is, his craftmanship! If however this bow was made by you and you weren't satisfied with the results, I made suggestions that could or would improve it's performance.
I have a nice collection of wood bows made by others. I would not consider making any changes to any of them. Their value is in the work of the craftsman that made them and not is the bow itself.
