The Billings instructions are really lacking. Their part numbering plans have me scratching my head! The fittings in the piping diagrams in many instances don’t fit the predrilled holes for the pipes. A real mess. Short of soldering it’s impossible to fit them together. I’m trying to find a glue that will hold. Anybody have any suggestions?
Ca glue is best for joining pipes. You can also use the CA glue accelerator if you need an instant bond. The worst area I dealt with was attaching the whistles to the top pipe and for this I drilled the pipe and whistles and superglue them with a piece of paper clip as a stiffened.I just built this boat and Billings is famous for its lack of directions but the kits are great. As to the flashing I would suggest cutting off the vertical bit and leaving the horizontal piece until you glue the top rail on, then trim it to fit otherwise you can overtime and face some repairs. I speak from experience.
