Hi, I want to build two different boxes of drawers, one with two drawers and one with one drawer under my bench. Since I have not done this before I thought I would ask you guys. Do I build the box for the drawers first and then the drawers to fit or the other way around? I was thinking about making the box and the drawer boxes out of 1/2 ply and then use a hard wood for the face. I was also going to use the Kreg system of hole drilling and screws and glue all fitted parts as well. I was also going to go with metal slides. Here is a small drawing of what I had in mind.
