I made a jig to keep everything in alignment when assembling the drawers but seems I didn't take a picture of it. The drawer bottoms are set in rabbits made in the sides of the drawers. As all drawer bottoms are identical they form the main way to align the drawers and keep them the same shape. The video shows how I modified the standard drawer pull to adapt them to the corner drawer. I selected pulls that mount with screws driven in from the outside of the pulls - works great for this application. Except for the drawer fronts (pine) the drawers are made from 1/2 inch baltic birch plywood. This plywood is nice and flat and easy to machine.
Full extension, heavy duty drawer glides give full access to the drawers.
Dovetails, dowels, corner blocks and glue all work together to make the drawers sturdy and rigid.
I finished the cabinets with a clear water based finish putting extra coats on the insides of all drawers. The finish has held up well.
