I wonder if a full bridle joint wouldn't be an option on the top rail/leg joint? Or, a dovetailed stretcher from the front center to the back. Either or both would add a bit of strength. I think I read the whole thread, but didn't see details on the joinery. I am assuming that the drawer runners will be M&T, front and back. French DT's for the drawer fronts? Curved rails are to be bent laminations?
Looks like the side edges of the drawer fronts will be coming to a point,and if so, will be prone to chipout in use. Might want to leave a bit of meat there to avoid that. Drawer fronts to be bent laminations also?
Are you sure we can't get those cockbeads back? That would provide some shadow line interest on the vertical.
I like the idea of doors on the ends, and suspect they could be bagged pretty easily.
Love that SU. Wish I had another 6 hours in the day so that I could learn to use it. It is not the price that bothers me, just the learning curve.
