Fiberglass for the Cockpit and Butt seam of the Hull

Do you like the title?

The cockpit is reinforced with two layers of fiberglass and three layers of fiberglass tape.  This was tricky.  Going over all of the different angles was challenging and it took patience to work out all of the bubbles.

I started on the plate, which is the highest part.  Before I started I spent some time making sure all of the seams were smooth and shaped to accept the clothe.  

I didn't take the time to make all of the seams fully smooth, but I don't think it made a difference in the end.  

The corners were the most difficult, but dabbing with a bristle brush help pull the air bubbles in the direction I wanted or allowed them to escape.



Overall the underside was not difficult, but I did end up with some bubbles under the seams.  Next time I will try to have each seam of tape rolled up and gradually roll and wet out the seam.  

Each stem required a filet of heavy epoxy.  It was the consistency of putty.  I wish I recorded the mass of wood flower per 6 oz of epoxy so I could quickly measure and mix.  I also purchased a spatula to apply the epoxy and smooth out the stems.  A little mineral spirits cleaned the spatula easily.

The hull also received two extra layers of clothe to reinforce the butt seam.  Afterward I sanded out the hull since I once again had outgassing from the wood.  I don't have control of the temperature in the shop I am working in so I just have to deal with the extra sanding.
