Always glad to be of service to a fellow OTTS member. Snowing here - off to neighbors for supper with the youngest. The middle boy is happy to stay home with snacks and his video games. The daughter finally has a party to go to - such drama. I cut off the couplers from a battery powered K-Line GP9 I've been cannibalizing for years, used various pieces of plastic from the packaging for the youngest's Spiderman web-shooting thingie, and glued the couplers to Thom and Percy - let's see if they hold using just model glue.
