I purchased the Suncoast kit and assembled for a customer. I also wanted one for myself so scratched built it along side the kit. Attached is a PDF file showing the construction technique. One thing I did find out is if built to instruction sheet the kit tower is not tall enough for the newer locomotives - see below. Since I will be backing in hoppers and gondolas I kept this tower for myself. My customer however will be passing locomotives underneath the tower so as shown in the PDF file I re-designed his tower to be taller.
