Official Luthiers Forum!

Please provide some documentation, that is not anecdtal, that has analyzed the problem in such a way as to determine that the glue alone is the problem and that it was used properly.

A quick google search of titebond and cold creep turns up mostly luthiers and anecdotes.

How come no other industry seems to notice this?

What gets ignored are the thousands of guitars that exhibit no creep at all vs the few per several thousand that DO creep, with no explanation of causal factors.

Indeed I have not been able to find this info either. And as I stated earlier using a properly prepared and fitted and stressed joint I can not reproduce it. I personally don't care what anyone chooses to believe but stating there is study stating there is research and not showing it is not educating anyone. The last step in a scientific method is to share your research and let others judge it's credibility.

Happy building, Tim

I mean almost every manufacturers use titebond, Gibson, Taylor to name a few. If it's such a problem they wouldn't have used it because it would mean warranty problems.

I guess I'll go test various types of white glue sold for woodworking in Taiwan... They are mostly white glue made by Taiwanese industries, generally sold for renovations/contractor...

Cold creep with aliphatic resin glues has been very much over hyped...! Does it happen...could be..some say they have seen it so I will not doubt their data. But I have been using this type of glue for about 40 years and have not seen one case of cold creep. Can it move if it has been exposed to heat...........sure can and most of us have seen that. As a previous post stated why would all the major guitar companies still be using this type of glue if there was cold creep all over the place. Anyway this is just me expressing my opinion on cold creep of aliphatic resin glue.

Yes. And hide glue can as well. Hide glue is composed of collagen, which is an organic thermoplastic protein polymer. It can also fail completely under the right conditions, I've seen plenty of popped and slid HHG bridges and braces.

All working glue except for glue rated for high temperature (for example heat resistant epoxy) will fail under heat.

It has been common practice for most of the large manufacturers (including Martin till recently) to scrape the gluing surface of the soundboard 1/8" inside the bridge footprint.
Besides reduced gluing area, the resulting thicker glue line is certainly more susceptible to failure than close wood to wood contact.

What they do is mill a ledge so that the bridge makes full contact. I tried that but without fancy Cnc equipment I can't manage to get a good even ledge when the bottom of the bridge must be curved to match the soundboard.

I'm accusing this thread of cold creep.
