quick follow up question
I am going to rabbet the top edges of the side panels to receive the front and back stretchers (left to right). I plan to make them about 3 inches wide from 3/4 material........should I just attach the side rails to the sides and fit them between the front and back stretchers? I am thinking that's pretty much the only way to do that.......
Here's how I prepare the parts.
I rabbet the top of the ends 3/4" deep, 1/4" wide, front to back.
The front and rear rails sit in the rabbet, and are flush to the top of the ends.
The top inside edges (at the ends) of the front & rear rails are rabbeted 1/4" deep, 3/4" wide, for a bit over 3" to accept the side rails which have a corresponding rabbet on the underside of the ends to fit into the front and rear rails.
I dry fit the front and rear rails and measure for the side rails to be a tight fit.
IOW, the rails are running around the whole opening, and their top faces are all flush. The end rails sit into the rabbet on the edges of the F&R rails. I use glue, and for that width, I use a staple to hold things in place, and then 2" screws countersunk to fasten. I add a clamp to where the side rails meet the front & rear rails.
I machine all the parts first, then assembly is done of all the parts.
