Day 15

6/10/2012

Today started with more sanding.  I started with 80 grit, then 120 grit, then 220 grit over the entire boat.  Once everything was sanded smooth and any gaps filled with thickened epoxy it was time to fiberglass the hull.  All edges had to be rounded out to a 3/8" radius because fiberglass will not lay across sharp corners.

I also applied masking tape at the seam between the hull and the shear panel to prevent any epoxy from dripping onto the shear panel which would have to be sanded later.

With the boat lying in the cradles upside down I laid out a large sheet of fiberglass cloth completely covering the boat and overlapping all the edges.  

It looks like a burial shroud.

The fiberglass will not stretch laterally or longitudinally, however by working at a 45 degree angle across the grain it is possible to completely smooth out the cloth.  It took some time to get everything completely smoothed out, but it was time well spent.


Un-thickened epoxy is them applied to the cloth with a plastic squeegee which causes it to turn translucent.

The bow and stern have to be cut, then the excess material overlapped and wrapped around.

The most important thing here (other than not having any wrinkles) is to apply enough epoxy to completely wet out the glass while not having too much so it pools and causes the cloth to float.  I used my squeegee to pull the epoxy from the chine down the sides.  The drips just ran down into the excess fiberglass cloth.

Here you can see the overlap of the cloth at the stern.  Eventually that will be feathered in by sanding and additional coats of epoxy and will be completely invisible.

After the epoxy has cured several hours, but not completely cured, a sharp utility knife is all that was needed to remove the excess cloth.


Here is the bow overlap.
