The project crawls along, measure 3x cut once. Home depot 1/2" Birch plywood had some flaws that were revealed when I cut the pieces. I only buy there since I can buy 2 ft x 4 ft pieces . I don't have a wood rack area to store much in the way of wood leftovers. I measure the thickness of the full extension drawer slides - just as well - they are thicker than the stated 12.7mm. The hardest part is building a "cabinet" but not being able to build the entire box , because the Aliner provides the back and base. It needs to be all-square, but most importantly the two sides need to be parallel. And then the notch for the wheel well adds a complication, because I lose my lower right hand corner as a control point. So I am deliberately taking it slow, so I have time to think things over. The cabinets structure will be fully screwed so it can be removed if need be. Drawers will be screwed together, but I may glue the drawer base into its mating slots as all drawer parts are plywood and won't change size.
