Spars for Cape Henry 21

Once I had the Bulkheads cut out and things like the rudder and centreboard case made I decided to make most of the longer spars while I had the space to work. Above are a few Photos of the building of the birds-mouth mast. This is a hollow mast made from narrow strips of wood that the corner of each piece fit in a right angled groove in the edge of it’s neighbouring piece to make an, in this case, 8 sided spar that is then planed and sanded into a round cross section.

It’s far more complicated to describe than actually to do, although it is a bit of a challenge handling very flexible 20′ long 2″X1″ pieces of wood in a 20’x22′ space. I did a dry clamp up on the trestles to make sure it would go together. When I was satisfied all was well I did the final glue up, after a frantic 20 minutes spreading glue, in custom cradles I lay along the level floor. It worked out well and the finished mast weighs around twenty kilos which is pretty light for a mast of this diameter.  The boom and mast are simple rectangular laminations for the moment, I might make them round to improve their looks and reduce their weight a little in the future.
