TrackHorizontal Support Ladder

All base ladder and support posts are HDPE (plastic / ??)  joined with stainless steel screws.   Posts are spaced at 24" o/c and driven into grade as far as they will go, varying between 8" and 24" depending on soil substrate.  The spacers between the posts and the double horizontal runners are located at  8" o/c and are used for securing the track.  The HDPE was obtained at Lowes and Home Depot and is impervious to rot and termites etc.  Support system was installed to exact vertical grade prior to adding the rocks and soil to enable as perfect as possible a smooth running track system.  One of the horizontal runners was installed to the exact vertical grade with assistance from a laser level system and the second was installed later to allow cross slope of track at curves either up or down for realistic horizontal banking.  A 20' long jig was made to mass produce the runners with spacers as seen in some of the pictures.
