The stock for the drawer rails and runners is 1/2" thick. If a 3/16" chisel was available for the mortise, that would've been nice. A 1/8" mortise would be too small and the 1/4" would leave thin walls. Given the low stress application, 1/4" was chosen.

The back was to be rabbeted all around to inset boards to close it in. This was interesting for two reasons. First, the side pieces could accept a through rabbet so I got to use my new-to-me Record #778 rabbet plane. The rabbets in the 3/4" stock were 1/2" wide and 1/4" deep.

A method was used from Lost Art Press' "The Woodworker: The Charles H. Hayward Years" books, chiseling out (bevel down) a triangular cross section close to the layout lines.

The carcase material was fairly cupped - about 1/16" to 1/8" - so a method was needed to clamp out the cup. The cup was on the inside faces - the outside faces were bellied. First a couple of dovetail-shaped clamping cauls were made.

The glue-up was very successful, removing practically all cup. I had been looking forward to this so that the joints could be planed and the dovetails really evaluated.

Very happy with this. This was probably the best corner. Some others were a little gappy, but not too bad.
Later the drawer dividing rails and runners were glued into place.

Next it's on to making and fitting drawers - coming soon.
