Just like a car I imaging, put your part on, send it down the line. Hot glue it together. Probably build a ton of them every day. The covering I would think would be the hardest, but with pre cut sheets, it wouldn't take that long.
So true -- That means you don't want to buy an ARF that was manufactured on certain days like opening dove/deer season, any world series days, day after Superbowl, etc...
