"How to build a 1/4 scale demoiselle model" Hello together, I'm from Germany and I want to show you how to build a 1/4 scale Demoiselle. I will do it step by step and I hope you enjoy it. greetings Gabriel Alberto Santos Dumont's aircraft were slightly in construction. Many of the supporting parts are made of bamboo and metal tubes. The Demoiselle No. 20, technical data from the Musee de l'air documents. Wingspan 6,35 m Length 6.65 m Height 2.20 m Weight 120 kg 1 x Dutheil-Chalmers (Darracq) 35 hp My 1:4 scale model: Wingspan 1,58 m Length 1.66 m Part 1 The material: Pine strips Pine round bars Brass Brass tubes Copper wire Steel wire Cable Solder, and various small parts Photos 1 show the drawings and lots of photos from the Musee de l'Air in France. http://s14.directupload.net/images/111006/xblucsqg.jpg Part 2. All clamps are drilled for the brass tubes. So we get a better grip and the alignment is much simpler. First we build the fuselage. Lay down two of the wood strips on the plan and transfer the position of the clamps. The tubes we cut to the length and then solder with the clamps. One of the pictures shows the universal joint of the tail and you see the front section with the motor mounts. The main part constructed with five brass components. http://s14.directupload.net/images/111006/ak7toc6d.jpg http://s14.directupload.net/images/111006/fmftvsrh.jpg http://s14.directupload.net/images/111006/papymfva.jpg http://s14.directupload.net/images/111006/qeiwviqh.jpg http://s14.directupload.net/images/111006/xiq6r4qx.jpg http://s14.directupload.net/images/111006/xhbmqimg.jpg http://s14.directupload.net/images/111006/tozjlxn4.jpg |

Wow! Great stuff, Gabriell!! |
have you welded them togheter with simple tin? And how do you made the two "X" in front of the plane? |
Absolutely IMPRESSIVE! Perhaps it'd be better move this thread in the Scale section. It's more appropriate for such a beautiful scale model :wink: |
Hello together, many thanks. If it is better please then move my thread in the scale section....it's ok. The questions. 1. The X-shaped struts are pressed by half at the crossing point. Then you put small pieces of wire on this point, wrapped round with thin copper wire and soldered everything. 2. It was soldered with solder for water pipes and with Degussa silver solder (hardsolder). greetings Gabriel |
Part.3. Now, the spoke wheels are ready and installed for a test. I will report in next time. greetings gabriel http://s14.directupload.net/images/111006/cbmnuufs.jpg http://s14.directupload.net/images/111006/craxvhd9.jpg http://s14.directupload.net/images/111006/e4aooegz.jpg |
Next. The front and rear fuselage components are static components. These parts were brazed with "Degussa silver solder", all other components soft-soldering. Hard soldering Degussa silver solder without coating Degussa H Braze Tech Micro Gas Torch Soft soldering: Soft Solder 1,5mm dia. Solder Iron Paste http://s14.directupload.net/images/111006/zhas9trr.jpg http://s14.directupload.net/images/111006/yh6gjbfr.jpg http://s14.directupload.net/images/111006/77nhuzof.jpg http://s14.directupload.net/images/111006/vp8pfsrw.jpg http://s14.directupload.net/images/111006/zrtkgtce.jpg Thanks so much for your interest. Greetings Gabriel |
Sorry I forgot, that's the finished model. http://s14.directupload.net/images/111006/zb6i5tnq.jpg http://s14.directupload.net/images/111006/pxf4rxad.jpg greetings gabriel |
