Step 3 Laminating the full blank together
After the epoxy cures locking the shaft to the core of the rudder I cut two pieces of 4oz fiberglass cloth and used a 1/8 inch piece of balsa on each side to lay up the complete blank. The 1/8 inch pieces brought the total thickness to the required 5/8 inch. More epoxy to wet out the glass and wood layers and then find some heavy stuff laying around to pile on top to provide some pressure for it all to set up. Now the full blank is done.
In hindsight, the glass layers inside the blank were probably unnecessary. By the time I had cut/ground/sanded the blank to its final shape, the great majority of the glass had been removed. Also, the glass layer was very hard compared to the balsa on either side making shaping much more difficult. Next time I'll leave these layers of glass out. |  | The inside layer of glass fiber
