Drywall screws vs. Joint strength test finewoodworking. Is located in the beautiful city of woodworking mach Search Go. Woodworking in poorly heated spaces during winter months often leads woodwprking glue failure.

Further testing needs to be completed, but that will probably be the next glue test. When I first got started in hand tool woodworking, I built a bench and the joints were not as clean as they should have been. It was suggested I should use gorilla glue or another polyurethane glue to fill the gaps in the joints.

This solution seems to make sense and tends to be the common knowledge answer to gap filling in less than perfect joints. As a result, I fully expected the Gorilla Glue to hold up very well filling a large gap, but I was extremely surprised. Not only did the Gorilla Glue fail early, but it was consistently at the bottom of the list of glues used for gap-filling. You would be far better off using a thick or gel CA glue to fill a gap than polyurethane.

Moral of the story, do not use Gorilla Glue to fill gaps. One of the key things I wanted to find out in the test was whether there was a difference between liquid hide glue, such as old brown high glue and Titebond hide glue, and dry hide glues that you mix with water in a double boiler. Though there is much to be said for the fun of making your own high glue in a double boiler, the test showed that in most instances the liquid hide glues did just as well, if not better, than their dry counterparts.

The data was enough to show me that, unless I really want the fun of making my own high glue, the liquid Titebond hide glue would do just as well as an average wood joint glue. In the past, if a project was going to get wet, I would use Titebond III to glue the joints together.

All PVA glues, including the Titebond series, did very poorly in the exterior conditions. Several of the blocks from Titebond II and Titebond III did not even make it to the test as they fell off when being carried to the testing rig. The evidence was more than enough to convince me that from now on, in exterior conditions, I will be using epoxy or even CA Glue instead of the PVA glues. One expectation I had was that the PVA glues would be vastly blown away by the superiority of epoxies and other high tech glues.

The strength for most of the PVA glues was far more than would be needed for any joint. This test was designed to find out the strength of the glues regardless of the strength of the wood.

Almost all of the glues tested would cause the average wood to fail long before the glue would fail. While some of the numbers are very impressive the glues tend to be far stronger than they need to be. Many of the assumptions going into the test were destroyed, several were upheld and reaffirmed. For most wood glue joints, PVA is a fantastic glue that will serve the user very well.

Hide glues are a very respectable glue with several benefits other than their strength. For exterior conditions, epoxies really are worth the expense and time needed to complete the project. Although in the past I have laughed at the idea of using a CA glue, I will now be adding them to my normal use as legitimate wood glues. For detailed information on how the test was conducted, you can watch this video.
