dust Posted January 4, 2003 Share Posted January 4, 2003 When shaping the bottom corner, the first real forming that is done on the plane, we struggled to "get it right" to our expectations. We are building two planes and no one knows which plane is whos, so not only did we want the right to equel the left, we wanted each right to equel each right and vice versa. Well the solution for the first 2/3 of the curve is quite obvious and universal amoung builders. The curve is constant so a sanding jig can be fabricated using the materials at hand and that you are comfortable with. For us it was Wood. We glued two 2x10's together, cut and sanded the curve, glued on sandpaper and double tapped skid plates on the Fuselage bottom and side, rough cut edge with sabre saw,rough sanded with sanding block and then finish sanded with form. The problem came from the final 1/3. Well, we sanded and filled with pour foam and sanded again and again until we (spelled Thane my partner) got one side looking gooooood. Now how to get the exact same shape on the other three edges. Well, Dave came up with the idea, each ten inches we drew a line and taped plastic on curve. then we rough cut a piece of plywood to fit over edge.. We then laid down a line of bondo on the plastic and set the rough cut curve into the bondo and let it set up/marked the position of the longeron on the curve and now we had templets for every ten inches to sand to. It worked so well that the laid up "in place" landing gear covers fit BOTH planes.
