This is the carcass for the drawer base. Had to get it together since all else installs on top or around it. Kreg system worked well. Used a little glue during assembly. The wide board lying on the table is the front stretcher that gets installed under the top drawer slides.
Good thing I did this, ’cause I quickly found out that I’d made the shelf unit side panels that go on top too long – misread my own plans when I transferred from the plans to the cut sheet. A couple of quick cuts solved the problem – sure better than looking for the board stretcher!
