The benchwork needed to be designed to fit onto an existing desk. I created a “box” that allowed a 34×60 by 2″ foam to sit inside. While eventually it will be glued down, it is removable, so I can pull it out and take it to the garage to transfer the design and lay some of the hard-to-reach track. The top yard will sit 3″ above the main track and have a 3% grade to access it I will post how I did this in a future article.
