I just finished the reverse side 1/4 foam that will become the spars and ribs. This time I mixed my micro super thick and spread it really thin. This made us easier to get it flat and I feel helped avoid bubbles under the BID.
I again used the bias cut method for cutting the BID recommended in the manual. It worked great and the key was how I rolled up the fabric after cutting it. The first piece I rolled with the longest edge exposed and unrolled it along the 24″ length of the foam. The second piece I rolled with the angle cut edge exposed and laid it on the first to get the proper overlap and unrolled it diagonally. I left the pieces untrimmed and I’ll cut the excess off after cure. I used a lot of extra resin, spread it gently very thick and gave it time to soak in before working it in to the BID in two directions along the weave and removing excess.
The back side of the 1/4″ foam with excess fabric left. I’ll trim it after cure.
