The Assembly Line
With all my pieces cut to size and the dados cut, I lay them out for assembly. Here you see the back of the cabinet in the middle, the left and right sides with rabbets cut for the shelf-tab tracks (to be installed later) on either side, and the cabinet bottom leaning against the assembly table, which fits into the horizontal dado. Well, they're all horizontal right now, but I think you know what I mean.
I didn't do rabbets for the sides. I probably should have, but with the glue, plenty of cement 2" coated finish nails, and the fact that these cabinets will never be moved, I think it will be plenty solid.
And here you see the raw carcases of the cabinets stacked where they will end up, except the upper cabinets will go against the ceiling.
