I normally don't attach the back of the cabinet until the later stages of completion, but it's been such a long time with this particular cabinet, I guess I did permanently attach the back panel months ago. The small problem this introduces is that I cannot fit the drawers in completely for there is no way to get them out again without a pull on the drawer fronts. Fortunately, the fit was so good that a strip of masking tape is all I needed to pull the drawers out from their fully closed positions.
There is considerable hand tool work involved in fitting the drawers, but relatively no dust is generated, just fine shavings. I also prepared the bottoms for the drawers by rabbeting a solid wood panel on three sides. The rabbeted portion fits into the groove on the drawer front and sides. The drawer bottoms are easily removed for any reason which might come up. I also loosely attach the drawer bottom to the back of the drawer to allow for some wood movement between seasons. In the photo, the lipped drawer in the foreground has the bottom partially installed with rabbets and grooves visible. Next I make the final test fitting of the drawers and install the cabinet interior divider I prepared in the meantime.
