Intended to test the lateral strength of the cope and stick joint VS walnut or maple. however we had 2 samples of Phoenixwood, and only one of the walnut. So I tried to just test the shear strength of the PHWD by clamping 3/4" of a 3" stile and applyng pressure to the stile at about the 2 1/2" width. not enough leverage for such a test with as light a scale we had.
