Securing the Subroadbed

In our most recent work session, we fastened down the subroadbed--1/2 inch plywood cut out to shape--so it is secure.  We installed risers to do the job.  The riser were made of scrap 1X3 inch lumber with a 1X1 inch rail fastened to the top for added support.  The riser rails were attached to the risers with wood glue and nails.  The risers were then screwed to the 1X4 benchwork at the correct height and the subroadbed screwed into the risers.

The risers were fabricated from scrap 1X3" lumber with a horizontal rail attached for added support

The subroadbed was secured to the risers with drywall screws
We completed the job of attaching all the subroadbed to the benchwork.

We then made some conforming cuts in the plywood base to accommodate a planned gorge and river bed.

Even after carefully planning the elevation of the subroadbed, we discovered some places where the superelevation lay in the wrong direction or was higher than wanted.  We loosened the screws holding the risers in place and adjusted them to level them properly.

A check of the level showed the logging camp area to be out of level; we adjusted the lean of the riser to correct it
We are satisfied that we now have the benchwork in place, ready for laying track.  In our next session, we'll be laying cork roadbed and preparing to install track.  So we're getting closer to running trains!  It's getting exciting!
