I got an email from Titebond today that also had this information from their web site.

I almost always use Titebond original. Though Titebond 3 is about 10% stronger, a well-glued joint is stronger than the wood around it. So really the major differences are

• Cost -- original is cheaper, 3 is most expensive

• open and assembly time, --if this is important, you might want a glue with more (or less) time

• chalk temperature -- the minimum temperature at which the glue and wood must be for it to work effectively, garage shop in winter?

• water resistance -- useful for outdoor projects

Thanks, Keith!
