I thinned the filler and used a palette knife to apply it to the wings. It sanded smooth fairly easily so I did the same thing on the jet intake/fairing areas. This first application is to smooth all the sections together and the top and bottom sections will get it next. When all 3 sections are done the whole thing will get an application of filler. This will dry overnight until about 11 tomorrow morning when it should be warm enough to go outside. |

| Thanks David. I actually understand! And plus after I read this, I looked at your previous posts and saw one I missed. Your Jan 16 posts that illustrates this process.Thanks again. Phil |

| Beautiful bird David!! Did a clear canopy come with the kit or will it be carved? |

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. |

You probably know that balsa will bend more easily from A to B than from A to C and that it will not bend in both directions at the same time. |

I studied the plans quite awhile before starting and this is part of the reason why. This is one of several parts provided to cover the open areas. |

| Temperatures already in the seventies? In January? Beautiful model DD. Thank you for taking the time to explain your reasons for using 1/16th squared balsa around the rear of the fuselage. I'll remember that for possible future builds. Is there any advantage over say, wrapping 1/16th or even 1/32 sheeting? |

| Lotta filler to cover a lot of lumber. It reached 23 deg. F. here today. I really like the stump table. |

Temperatures in the seventies allowed sanding and the first application of filler. |

Fabricating & fitting |

Those gray things in the exhaust, called vanes, obviously would not be on a real jet but they align and support the rear of the model. The reason for using all those 1/16" stringers was to keep the opening as close to a circle as possible while gluing them to the paper. It's quite strong. You can't see most of what's inside now so painting it all black will effectively cloak it and all you'll see is a black hole. About a inch and a half of the outside from the rear will be painted a dark metallic. |

| hi tech! by you and the model! |
| David Duckett, Comment for image # 35406 | 20 Jan 16 17:04 |
| The exhaust will be painted black once those pie shaped pieces are removed. |

| Most of the fuselage is planked or sheeted with 1/16" wood. The infill on the wings is 3/32" wood. |

| so you used 1/16" balsa to fill the gaps david? |
| rayl, Comment for image # 35406 | 20 Jan 16 11:57 |
| Lotta lumber there. How are going to finish off the exhaust? |

| I've seen that one. If I start building that size again, we'll need to get a bigger house. |

| Ya, no kidding. Looking good DD. |
