Check out this month's FWW. Used saddle joints to test different glues. Good 'ol Titebond led the pack.
But they didn't use the domino!!!!

They did actually use the Domino in a recent test. In the July 2007 issue #177, they test the Domino against biscuits, Dowelmax, Beadlock, and a mortise and tenon joint.In the shear test, Domino rated 464 pounds of force to break the joint. In the pull-apart test, 1486 pounds. The tests were made in "2" red oak with yellow woodworking glue." Wood failed before the joint.
Very interesting. Thanks for that. FWW did a test several years ago comparing biscuits, M&T, lag screws, and dowels for a butt joint. As I recall, three biscuits were stronger than the M&T, and two were nearly as strong.
Something that surprised me was how strong all the joints were. I wouldn't have expected an unreinforced miter joint to hold up to 130 lbs.

Very interesting. Thanx for posting.I would have liked to see them test pocket screws.Chyck Slive, work, build, ...better with wood
The guy on the video mentioned lots of tests in the beginning that weren't actually shown in the clip. I guess they're trying to get us to buy the magazine. ;)
You notice, they concealed the superiority of Piffin screws by not even mentioning them.
Forrest - knowin' the truth
shhhhhhh! It's a secret!
