Stringer Rebuilding and Galley demo

This post covers a couple of day sof  work...because I am usually too tired to post every night.


Started off with finishing the rebuilding of the rotten stringer. Here is the new plywood screwed, nailed and glassed to the top and bottom wooden beams. First I coated both sides of the plywood with 2 coats of resin to seal it. Then I did the same with the beams. Next I filled the bad spots where I had dug the rot out of the lower beam. The plywood is glassed on with 2 layers of 1.5 Oz. mat between the beams and the plywood. It is screwed into the top and bottom beams every couple of inches as well.
 Next I applied 2 layers of 1.5 Oz. mat to back of each of the original pieces I cut off the stringer and then screwed and nailed them to the plywood. They are nailed through the plywood and into the beams every 3 inches or so. I will be glassing over these pieces so I wanted to make sure they were well fastened to the beams. I will remove all the screws you see in the middle areas. They were used to make sure the glass pieces were well bonded to the plywood. It not very pretty at this point, but once I grind all the rough spots down, fill the few gaps and then apply two layers of 1.5 oz mat with 24 Oz. Roving over them they will look great. Oh yeah and be a lot stronger than the original work which was two layers of mat with 1 layer of roving in between. Final glass thickness will be
3 - 1.5 Oz mat + 1-  24Oz Roving +  2 - 1.5 Oz mat + 1-  24Oz Roving +1- 1.5Oz mat + 1-24Oz Roving.

But first I needed to remove the old freezer and cabinet from the galley area over the stringer. I want to be able to wrap the glass over the top of the stringer, which means you have to be able to get to both sides of the stringer.
Tomorrow I will continue with more cabin sole removal to expose all of the stringer in this area. They did not do a very good job of leveling the stringers up before they glassed them in so they had to add strips on top of the stringers...Lucky for me, now I can remove those strip from the center stringer which will give me the room to wrap the new glass work over the top of the stringer.
That's all for now.
