Now that the front molding is cut, I can start work on the center self
support, and the back frame.
Cutting shelf support
 
     
The bottom and top of the shelf support is rabbeted into
a stopped dado cut in center of top and bottom shelves.
 
The top and the bottom of the center support has a
sliding tenon to fit into rabbet in top and bottom shelf (see above).
 
For middle shelves the center support fits with a
lapped joint. Basicly cutout a section of at the center of the
shelf to fit the center support.
 
A similar cut is made in center support to hold
each shelf. These were fixed so that the center support is indented
into the shelf by 1/4 inch. The selves will be trimmed back to hold the
center support for the back panel.
 
Here is finished center support.
 
Rabbet for Back Frame
 
I cut a 1 1/4" rabbet around the inside of the
back to fit the frame into. After cutting a stop cut with my backsaw,
I used my chisel to remove the rest.
 
More removal.
 
After cleanup the rabbet looks nice.
 
Here you can see the rabbet to hold the back around inside
of back.
 
Here is a better shot looking at side, I still need to
trim the shelves so that center of back will be flush with center post.
 
Cut out for frame on top.
 
Showing the ends where I did left dovetail. This
is so that there is not a gap at corner.
 
Back Frame
 
The edges of the back frame were routed with my plough
plane with a groove that will be used to hold the plywood back panel.
 
The center back panel support has a groove cut down
both sides of it. Next a tenon is cut at both ends to fit into a
mortise cut in center of back panel top and bottom supports.
 
Here is mortise in top piece.
 
Here is it put together.
 
Frame cut, test assembly.
 
Mortis and tenon joint for frame edge.
 
Kick (or toe) plate
 
This is a pretty simple cut, the kick plates were cut
to 2 1/4 inchs, then a 1/4inch rabbit was cut into top. Next a 3/8 inch by
1/4 inch tendon is cut on the ends. It starts 1/2 inch above floor.
