The drawer case (at 10mm) is half the thickness of the carcase (20mm). The (eventual) drawer fronts (one for each side) will be the same Fiddleback Jarrah as the top and sides, and will be inset (rather than lipped). The purpose of the thinner sides is simply aesthetic - I want it to look lighter, to subtly separate it from the carcase. The drawer front will be the same thickness as the carcase, and the drawer sides the same thickness as the drawer case.
Before beginning on dovetailing the ends, stopped dados were marked out for the drawer case. The lower- and upper panels were clamped together and a MDF template of the drawer case set in position...
Marked out, chisel walls made ...
... to guide the saw cut ...
Then chiseled ..
... and routered out ...
Following the method outlined previously, the two ends and the top were joined with mitred through dovetails ...
One edge ...
.. and the other side ...
The plan now is to size the drawer case sides before dovetailing and joining the lower panel. Why the templates and sizing at this stage?
When the two ends of the lower panel have been dovetailed, the two sides of the drawer case must be fitted before the panel can be attached. In other words, these three pieces are fitted together at the same time.
Now, as the sides of the drawer case run in a stopped dado, they need to be sized beforehand. This fitting is different and far more exacting that in the typical carcase which as a stopped dado on one side only, and the dividing panels (which I term the drawer case) are slid in, allowing one to mark where the front rebates will go. In the present build, the front and rear rebates need to be determined beforehand, and cut before the parts are brought together.
The MDF template is to aid in measuring up the sides for the drawer case. This is one of the (number of) surprises of this build: it looks so simple from the outside, but when it comes to constructing ...
In the photo below, the dados are checked for size with a 10mm wide template ...
An MDF template checks the case sides are parallel ...
At the far end is another MDF template to size the drawer case sides ...
That's it for now.
