I decided that it was time a built a module section of a layout at home in order to have a place to display the models I have built so far.  I researched several methods of benchwork construction and decided upon the l-girder construction.  I made this decision for the excellent combination of strength, relativly low cost, and low weight.  I began construction by first gluing and then using screws to attach the boards in a L shape.  This has the effect of creating much of the strength, while at the same time providing a place to screw the crossmember s to.

I screwed the parts of the legs together, not using glue as I intend to make the removable in case I have to move the module.  I then assembled the legs onto the two main joists.  One of the most import things during the assembly process was the use of a square, to make sure that everything lined up correctly.
