I had a chance to put pretty much every thing together and discovered an glaring error. The center of the first bay of the two - bay loading/unloading shed is supposed to be 9 inches from the building. This means the conveyor house from the building to the silos is too short. I will need to add an extension. I also don't like the 'down spout' to the top of the shed so am re-thinking that design. My plan is to either run a rectangular spout down the wall of the head house then straight out to the top of the 'spreader' on top of the shed or if I have the parts stay with round tube and maybe encase it inside some small truss beams. To me right now it looks like the pipe is just 'hanging out in the wind'.
Incidentally all the details you see are HO scale either Walthers or Faller. Once I fix my errors I will need to build docks for both sides of the brick building plus add mortar to it.
