Amazingly, I have only had one engine hit the floor over the years. It was a Bachmann HO Shay. It went front first, and fortunately it was carpeted. I was able to order all the parts and get it working again. My uncle was rear ended on his way home from the RC airfield once. He was more concerned about his plane being smashed than he was about the car. It was the first time he flew the plane after many hours of assembly.
Yes I can imagine jigs are needed to keep everything spaced correctly on the rick house! Looks good.
