The Five Holes or Fewer Secretary’s Challenge
This Challenge was an idea from Brian Leach. It was to build any model, but only using parts that have a maximum of five holes.
So, any standard Strip up to 2½” long — the new strips with ¼” spacing will allow only a 34mm (approx 13/8”) Strip. Brass parts with holes drilled through from one side to another were counted as one hole per drilling, so a standard Collar, part 59, will have two holes; the ‘4-hole’ Collar will have three holes; a Short Coupling, five holes, but a standard Coupling will have too many at seven holes. Hopefully, you get the idea!
