The first was to compare six common types of woodworking glue the second was to see if the type of wood might affect the bonding strength of the different glues the third was to determine how tolerant the glues are to poorly cut joints. note 1 Proper joint preparation is almost as important as all other considerations put together. They used a motice and tenon joint and different woods and different tightnesses of the joints.

There is also a lot of conventional wisdom. To see if that conventional wisdom has any basis Fine Woodworking ran a test on six common types of woodworking glue a traditional yellow glue PVA a Type I waterproof PVA a

Woodworking 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. Hide glue can vary in quality and it can go bad if exposed to moisture. Clamp time The minimum amount of time required before you can remove the clamps from a glue-up assembly. I m not a fan of poly glue I ve had inconsistent results and now use Titebond III - I like it. I was flipping through some back issues of Wood magazine looking for a project and found a test of 15 different glues in the September 2004 issue. Synopsis Glue is so essential to woodworking that there are dozens of types and masses of competing brands. Mark Schofield and Michael Dobsevage. The results were The worst Gorilla Glue. Others complain about the smell.

The glue is stronger than the wood. Note PVAs and hide glue offer only 30-50 of full strength at stated time. Fine Woodworking managing editor Mark Schofield goes behind the scenes of our methodical glue stress test to show you how we tested six types of wood glue.Schofield heads to the Department of Materials Science and Engineering at Case Western Reserve University for a peak at the Instron joint-breaking machine in action. Fine Woodworking just had a glue test. PVA cannot be beat for wood joints Glue starvation is a myth. It went fine not a lot os clamps but the long spline tenon on the desk top really grabbed in the mortise given the very large surface area but my cabinet clamps pulled it in nicely. If a joint is under stress maintain clamping pressure for the full cure time. Cure time The time it takes for a glue joint to achieve full 100 bonding strength. The latest Fine Woodworking contains a whole article on glues. Polyurethane glues are not for gap-filling. They tested plain PVA Elmer s I think Titebond III apparently a waterproof PVA System Three Epoxy and Gorilla glue.

Good-quality glue has a very mild animal odor. Some people have sworn off hide glue after buying poorly made or poorly stored animal glue from indiscriminate sources all around the world and then experiencing joint failures. Just finished my own glue-up this AM using Tightbond III for the longer open time where I would normally have gone with TB II Dark as it is mahogany. To help make sense of it all Fine Woodworking ran a test with three main objectives. Looks like the results we have always talked about and read about in tests. No real surprises there. Further testing needs to be completed but that will probably be the next glue test. Pretty amazing results at least to me . I am intrigued to see if CA glues can maintain their strength over time.
