An important part of the drawers was having them sized correctly for fluids etc.
The bottom drawer will have permanent dividers installed. Then, once line-x'd it will create a watertight pocket that will isolate the spillage to that pocket alone should anything break, leak, etc.
The upper drawer will be made to accept dividers later on if desired. The dividers will be made from black walnut to match the drawer fronts.
Here the box sits prior to final assembly, line-x, and cosmetic like the the drawers face.
