I have seen an article in one of woodworking magazines (don't remember which) that compared strength of biscuit joint against M&T in some practical test. Biscuit joint proved itself reasonably strong at the beginning, slightly weaker than M&T but not by much. The major difference turned out to be at how the joints fall apart. M&T starts slowly to give up as the load increases. Biscuit, as opposed to it, reaches certain point and then falls apart completely at once. In other words, M&T dies gracefully while biscuit just quits on you. The door built with M&T over time may start saging and cracking but biscuit door you will just find on the floor in many separate parts one day. |
