I'm planning to reinforce my v-berth as per these instructions
from the designer
- Sand the inside of the hull to remove any wax, glue, etc.
- Apply one layer of 1.5 oz. mat in this area. Catalyze the resin for a slow cure to keep it cool to prevent print through.
- Before the mat cures, wet the panel of 3/8" thick balsa with resin that will go against the hull and apply pressure to the balsa for a good bond. Note that you should taper all 4 edges of the balsa over a width of 2".)
- After this lay up has cured, apply one layer of 1.5 oz. mat and over this one layer of 1.8 oz. woven roving. This should stiffen the area considerably.
Most of that makes sense to me with the exception of the proper balsa material and the proper tapering.
From what I can see online (Nida-Core
) balsa comes in 24x48 sheets
in scrimmed and scored and solid form. The hull in this area is not an even run there is some flare to it and it will as Shaw mentions need to be pressed into place to ensure a good bond with the hull. Can anyone reccomend a proper balsa to use?
As for the tapering the full area to be reinforced is roughly 81"x 24" (it's actually a little smaller and not a rectangle). How much smaller than the total area should the balss be so it can sandwich to the hull is 2 inches (i.e., 79" x 22") good enough? will I also taper the edges as mentioned.
