Rabbeting the back...

My next logical step in the progression is to create the rabbets for the frame and panel back. The rabbets in the left and right side panels are fairly straightforward. I selected a 5/8 inch depth and 5/16 inch width for the rabbet. The 5/8 inch thick frame provides sufficient strength for the 5/16 inch back panels. The will be two back panels housed in the frame which is divided by a center stile, or at least this is what the plan is. It is fairly important to have the depth of the rabbet uniform in both side panels and the top and bottom panels, this involves careful measuring and allowance for the chamfer edge profile of the top and bottom panels.

The rabbet in the top and bottom panels is a stopped rabbet, ending just before either end of the back of each of the top and bottom panels. After removing most of the wood to create the rabbet, I squared the ends of the rabbet using chisels and careful marking. To ensure all the panels are squared up and exactly the same size I overlay the top panel onto bottom panel without the side panels and then with the side panels in place.

In the photo, the panels are loosely assembled to confirm all the rabbets are the same depth and uniform around the carcase. I also take this opportunity to mark the outline of each of the side panels onto the top and bottom panels. This paves the way for the next step which is to create the joinery for the panels, in this case dowels. I create a doweling guide which is the same dimension, thickness and width as one of the ends of the side panels.

More about this in the next post..
