The problem with using dovetail joints for floor joists are that the dovetail is going to shrink...................In the above drawing the red dimension is what is going to shrink. To offset the expected shrinkage hardwood wedges are driven in on the sides shown here at the blue lines...........

To offset the expected shrinkage hardwood wedges are driven in on the sides shown here at the blue lines...........A little misleading, as the red line is shown running along the grain where there is essentially no shrinkage. The shrinkage explained is for across the grain on the joist.
When you layout a dovetail, do you layout the dovetail shaped tenon the same dimensions as the corresponding mortise?
Jim,Do you have any sketches on how your sill/plate corner intersection would look on a small frame. I have done a few different things and have never been entirely satisfied.Dave
