I continued contrustion of the module by clamping the first cross member and screwing it into place.  This is one of the chief advantages of using the L-girder type construction.   It allows cross members to be easily moved if the design of the layout requires it.  I used a countersink bit to pre-drill for each of the screws so that I would not splinter the lumber.

I continued this process for the rest of the crossmbembers, just using equal spacing to start with.  I have not yet figured out a track plan as I am still in the process of building some of the chief industries for this module.  My intention at the moment is to model a meat packing industial siding, showing many of the different parts of the same industy.  My intention is create a small module that would be fun to run a small switching operation on.

Note that I have put some cross bracing in place.  I did not like the way they turned out so I will be be replacing them at some point.  For now they provide the needed support and I will leave them as is until I get further along in the building process.
