Has it been a year? Ok, annual update.

Looks as though the blog will be updated annually, apologies.  Here is all that has been going on since November 2018.  Quite slow, but surely progressing.  Most of the work has been foils and spars:

Final shaping on the rudder, endless sanding...

Final shape, ends rounded, prep for fiberglass.

Biaxial glass on one end.

After ends, fiberglass draped and coated on both sides.  After 3 wet-on-wet coats was not able to avoid runs despite my best efforts.

Mast and lug yard, before. Two 2x4x14' Douglas fir.

Despite paying for "CVG" (clear vertical grain) I ended up scarfing the 2 wide faces on the mast to avoid some knots in the lumber.

Glueing solo, I could only manage to glue one face at a time. During a dry run, I realized the weight of the clamps will change the shape of the mast.  

Final face was glued using fewer clamps and more packing tape, as indicated in the plans.  This may be the only way to finish with a straight mast as the clamps are just too heavy.

Lug yard glued and shaped from 4-sided to 8-sided and finally 16-sided, as pictured here.

Got some help with the boom.

Douglas fir sides, WRC infills with Douglas fir infills at each end.  Obviously, planning to rig the sail loose-footed.  Boom design is from the FB group, thanks to Aaron Robarge's diagram and Pedro Carlos da Maia's input/ experience!  Measuring deflection, quite stiff.


Finally we come to this week, fiberglassing the ends of the boom and lug yard.
