Well I understand everything your saying Pearl, but the only thing you have said that is definite is weighing the bow. and as you said if the sinew is dry and cured when you start, then it just the glue moisture that needs to be removed. This is some good food for thought, but I think my bow was dry and ready to work. I will keep an eye on it and report any issue/changes that come up. With this being my first sinewed bow I'm really taking notes.
Good post, Thanks to everyone for posting info it's really interesting.
