The machine shop had a much faster turnaround than we expected, and we received our parts today! Since we'd decided not to include some of the simpler pieces on the cut sheet, we first needed to hand-cut the remaining parts, mostly squares. First we marked the cuts we needed to make on the particle board and cut them in the wood shop using a band saw. Once we finished all of our parts, we started to put things together. To attach the two sections of the lid together, we were originally planning on using wood glue, but had difficulty finding the necessary supplies. In the absence of the glue and in the interest of time, we decided to nail the two parts together. This worked out well, and now our lid parts are complete.
To put the walls and the lid together, we have decided to use L-brackets, which we'll be working on for the next bit. Finally, we'll need to attach the hinges to allow the walls to open.
