| David Duckett | Berkeley Douglas F4D Skyray | Build | 23-Jan-16 06:55 |  | | Views : 403 | | The fuselage is about 4" diameter and the exhaust is about 3". Notice that the bottom of the fin/rudder is curved to fit that outline. I first glued one of the stringers to C to B and then from C to A. The problem is that at Point A it's paper. Each additional stringer is glued to its neighbor so all 120+ used are all glued together. That means that the original curve established is maintained lengthwise and allows control in placement of where the stringer meets the paper. The reason you can't do all that with one piece of curved balsa is because it's a compound curve. If you covered from A to C you would lose the curve. And with all the stringers involved being glued together it's quite strong which, by the way, is why I would never use 1/32". All surfaces will get filler and that means sanding so thin wood just doesn't work. Ever. |
