This weekend I concentrated on fiberglassing the dagger board while at the same time fiberglassing the top and bottom sections of the rudder.
The daggerboard was a little different from the rudder as I had glassed the top/bottom end ahead of time
I wetted out the fiberglass on the daggerboard while installing the fiberglass on the top end of the rudder.
I let it cure overnight and came back and trimmed the excess fiberglass with a combination of scissors for the rough trim, a block plane to get it closer, and finally 220 grit sandpaper to getting it exact.
Interesting enough I have come to the conclusion that it really did not make much difference between fiberglassing the top/bottom first vs. the sides. The good news is that the way I did it, which was one of each, worked out pretty well from an efficiency standpoint. As you can tell by the picture same difference!
I flipped both the daggerboard and the rudder and did the other side. Picture below shows the dagger board fiberglassed and reading for the coat of epoxy that will fill in the weave.
Based on some challenges with that I faced with the rudder I added some blue masking tape to the leading/trailing edge of the foil in order to mitigate any potential runs. Next steps is to fill the fiberglass weave on the the dagger board and get a decent coat of epoxy so I can get it ready for sanding and a coat of spar varnish. I also have to drill the holes and epoxy in handles to both foils.
My understanding is that it is a good idea to wait a couple of weeks prior to applying the varnish in order to make sure the epoxy is fully cured.
Next steps is to build the rudder hold down assembly and the tiller
