Don't worry about the legs appearing a bit off skew in the picture as its only held together by the friction in the mortice and tenon joints at this stage - they will be straight when glued and doweled.
The picture also clearly shows the empty outer mortices resulting from my design change. Currently I am making some short stub rails to make it look as though the rails do go all the way through. I have currently made 3 - the 4th's tenon is done and it just needs to be cut from the stock - which will leave 4 more to do. Then they will all need rough-finishing, rounding over etc before I do the permanent assembly.
