Trying not to screw things up worse
I have a small project that involves joining 2x4s. When it's done, force will be applied downward from above (direction of the arrow), and I'm wondering which joint will be strongest in that situation: the dado (A) or the rabbet (B). The dado removes less material, but the rabbet maintains the full 3.5" thickness all the way across.
(My own hand drawing; not to scale, obviously. Note that in both cases the lower 2x4, the one going across, is meant to be oriented vertically.)
