Not sure if I mentions above - I am building a plastic version and a wood version of the rural grain elevator.
I laminated all the plastic with clapboard siding. Below is a sample. After cutting off the excess plastic (there are sides where I leave extra clap board siding so it covers the overlapping perpendicular side).
I glued the main building and top house as two assemblies. One thing I learned early on is that to ensure keeping things square corner braces are a must.
For the second elevator I cut wood clap board siding. My original intent was to laminate the wood to the plastic , however I decide on eliminating the plastic and bracing the inside of the wood walls. I had enough clap board (so I thought) for all walls however when I started cutting the last packet I discovered the packet was mislabeled. It turned out to be board and batten. so more wood is on order. I am really starting to like wood for building structures more and more.
