This is a fairly simple storage unit designed to hold a variety of power tools. The panels are 16mm MDF, attached together with pocket hole screws. I used pieces of scrap wood (and a bit of imagination) to make the brackets and shelves, customised to suit the different tool types. Some of these involved gluing pieces together, but each shelf and bracket is screwed (not glued) to the main structure so they can be moved or replaced if necessary. The unit has four 50mm castors with brakes.
