This was started in another topic concerning body blank joining. The issue of glue types came up and it was said that TitebondII may not be a good choice. To sum it up for those who don't have time to read everything - Titebond (original) is not any better at avoiding "creep".
I asked the manufacturer about this and got some interesting info. The first message was in reply to my question concerning "creep" associated with TitebondII:
Thank you for your inquiry regarding Titebond II. Titebond II creates a
strong bond, but not one that is rigid or brittle. Titebond II can creep if
the glue line is under a long term high load. This creep could be
aggravated by high temperature and or a thicker glue line. A thicker glue
line would have less strength and be more capable of movement. The
recommended service temperature for Titebond II is between -20°F and 120°F.
At temperatures around 150°F, Titebond II can begin to soften and lose
strength. We would not expect a guitar assembled with Titebond II to creep
while stored in good conditions. I hope this information is helpful to you.
The next is the reply I got when asking if using Titebond (original) would help prevent the "creep":
Titebond Original Wood Glue would not be any more creep resistant than
Titebond II. Although, Titebond Original is used by many guitar
manufacturers. A wood glue of ours that is considered creep resistant would
be Titebond Extend Wood Glue. This product is used for assemblies where the
glue line is under a lot of stress, like bent handrails. I hope this helps.
