As a professional woodworker I use Titebond (original) glue all the time. That stuff is incredibly strong. I have also used TB II and TB III glues as well and they are all very similar. Clamp pressure is very important. In furniture making aplications, I clamp things together for as little as 1 hour, but the glue surfaces must be perfect...that is clean (freshly machined is best) and the pieces fit with no gaps. I know that this is hard to do with bow wood pieces or laminations, but remember that if you force things together with clamps which do not fit perfectly you are risking that the pieces will "creep" back apart. Which brings me to the drawback of Titebond glues is the have the tendency to "creep" or springback. This is due to the fact that the glue is plastic in some ways and this is why the bottle says not for structural (i.e. house framing) use. I am not sure that this a draw back for bowmaking though, because of the experiences of those listed in this thread. Epoxy glues in general respond much better to ill fitting joints, and lower clamp pressures. They also have much less or no tendancy to creep. This would be an asset when making a of bent laminations like recurves or setback handles and the like.
