Hi, still in the planning stage at the mo, but just wanted check the image is correct below as i have decided to build my layout with 48.3mm scaffold poles for the straights & 50mm waste pipe for the bends, then plastic decking to lay the track on. It seems a cost effective & weather resistant way. But, to bend the pipe i need to make a jig from an 9x4' sheet of wood & set up a jig to bend the pipe with hot sand packed inside. This will make up an R1 & R3 jig. So, for an R3 i will make two bends, 1at 1025mm & 1 at 1325mm to run in parallel around the bend & slatted decking across the two. & similar for the R1.
