Re: Steve's Mayfly 14 Build
- Generally speaking, all deck mountings are screwed in place from
underneath in traditional boat building. The screws also act as clamps
to tighten the joints until the glue dries. If you really want to get
fancy, hollow the bottom of the coaming surfaces a bit rather than
leaving them flat. That will really lock in the glue and prevent
squeeze-out wastage. This can be done with a small angle grinder just
held at the proper angle to not touch the outer edges or even some
coarse sand paper secured to a rounded block.. This can also be done
with rubbing strips or any solid timber attached to a plywood surface
clamped down with screws that will end up inside the hull. The screws
can be removed after and the holes filled but if they are corrosive
resistant can be left in even in - even in an open hull.
But - I am a believer in solid fastenings in addition to glue. Not

destruction test, one with just glue & 1 with glue & screws. You will
use screws too. If you glass it over you could probably get away without
screws just depends onÂ the loads you expect. I'm hard on equipment.
