While finishing up my Estes Lynx, started the work on the Mercury Redstone. First up is fin work. These required some more detailed processes. The wood used for this model is rather thick, or at least thicker than I am used to, but that is good. The 4 main fins are made of 8 pieces which are glued together and pressed overnight. The 4 smaller fins are regular squares to start. The fins need to be shaped - each has a 1/4" knife taper that comes to a 1mm edge. Small fin side view. Small fin view from top. Note - the second from left isn't really thinner than the others... just the ink marking on the top rubbed away. Main fins showing their knife edge.
