11. Fold down the flexible WC strip on either side of the stringer. The folded
down WC is used as a large surface area to stick to the other blade half
(windward half). The folded down strip should not be wider than 2cm from the
central stringer. This is to avoid the strip obstructing the expanding foam
during the filling of the blades.
Then add more resin to the folded down WC and along the inside of the
windward half where it will meet the WC (100g “inner layer” resin was used).
Carefully place the windward blade half onto the backward piece. Ensure it is
in the correct position. Place the blade back into the mould and clamp firmly
but not too tightly. This will keep the part from moving or distorting from its
desired shape while drying.
11: Lay the blade (in the mould) horizontal with the windward blade half facing
downwards so the resin will seep down into the join. Leave to dry for
approximately 6hrs.
