Mixing oil/varnish for mahogany with black milk paint for the poplar components is challenging my brain. Hopefully, to make things go better, I pre-finished the interior of the mahogany sides and milk paint horizontal elements. The milk painted pieces also received several top coats of oil/varnish for protection and appearance.
I drilled counter sunk holes in the case top. The show top will be attached with #8 screws. I drilled the front holes for #8 and the rear holes with #10 to allow for movement towards the back of the cabinet. Which should not really be an issue as all grain orientations will be in sync. I also drilled pilot holes for the knife hinges. Much easier now, than after glue up.
First stage glue up was case top and bottom to the sides. Half-blind dovetails were used for the joinery. I inserted the shelves to assist keeping the case square. Once that stage set up, I removed the shelves, applied some glue to the back and front of the sliding dovetail joints and applied clamps.
Later, I realized my liquid hide glue was far out of date. Hopefully, all of this will hold together. My multi-interlocking joinery addiction should make it work fine for my lifetime at least.
Next we get into the fun feature of this cabinet, the legs.
