Traxx is right, let it dry. Doesn't take long.
Ferret's bow building page, also, recommends sizing when gluing on a handle riser. It allows the glue to sink into the wood pours first, which enhances adherence. It is a good idea.
If I remember right you are planning on using TB3 like I do. To be fair, I have read that hide glue is supposed to be superior in drawing the bow into relfex upon drying than a synthetic. Whether this is completely the case I don't know but thought I would through that out for your information. I've tied my bow into reflex while drying with good results.
To me the trade off in weather resistence is more important.
