Back to work on the frame. I started by adding some inner 4" x 6" pieces on the center beam.

Next, some 4" x 6" cross pieces with some 4" x 4" pieces inside. This will frame the doors.

I had a sheet of .032" brass and I used this for the doors. First I cut it into strips 1’ 4" wide. These strips were cut into rectangles 2’8" long. I drill a hole in each one and then inserted an eye into each and soldered it into place. The picture below shows all of the steps.
