Fine Woodworking has done a comparison of joint strength. If you are a member of Fine Woodworking online or have subscribed to Fine Woodworking magazine you should be able to find it. If you don't subscribe to Fine Woodworking Online, I don't know if you would have access to it online. The lap joint and bridle joint were the strongest, but there are a lot of other joints that most likely would be strong enough based on their tests to break the joint apart. Dominos were a little stronger in this test than biscuits but I suppose not enough to matte much. Splined miter joints were not as strong as the half lap and bridle but very strong. They didn't compare dovetail joints because a dovetail joint is not really in the same category as these others although it can be used for some of the same purposes. Just thought you all might like the reference since it seems to be an important issue given the attention its gotten.
