Dandiego Posted December 24, 2019 Author Share Posted December 24, 2019 (edited) A little more prep work on the engines. First are the completed exhaust assemblies. My low cost printer leaves visible ridges on the parts. So to get a smoother surface I sand them down and then slather them with putty. After they are dry they are sanded again. The tubes are really a 64 sided polygon so the inside is sanded and putty applied to get a smother appearance. Next is the intake, 3D printed cone and tube. Turbine face is handmade, because I couldn't figure out how to design it on my computer. Some alignment aids have been added to the inside of the engine pod. Whole thing, getting ready to close up the pod.

Dandiego Posted January 3, 2020 Author Share Posted January 3, 2020 Micro update. I have sprayed internal engine components with Alclad gloss black. When dry I will shoot on some metallic colors. You can see completed turbine blades on the clothes pin. Slow progress when doing a vac. Nothing is easy, no alignment pins, nothing to support internal structures, lots of fiddly work.

Dandiego Posted January 4, 2020 Author Share Posted January 4, 2020 Another very small update. I have decided to add a thin metal sheet inside the wing which will extend out and then slot into the fuselage. Here is my cardboard template for the metal reinforcement. I will cut out 2.

Dandiego Posted January 6, 2020 Author Share Posted January 6, 2020 Micro update. I am waiting for some airbrush parts to come before I start applying Metal paints to the engines. So a little more cutting and gluing. Here you can see the undersides of both wings. I have cut out the well for the outrigger gear.

Dandiego Posted January 8, 2020 Author Share Posted January 8, 2020 I have cut out the metal inserts for the wings. First is the insert from the top. It will be epoxied to the plastic blank. From the underside. The protruding tab will be bent to lay flat against the bottom of the blank.

Dandiego Posted January 8, 2020 Author Share Posted January 8, 2020 (edited) This is, I believe, my final wheel design. I finally got a decent spoke pattern into the hub.

Dandiego Posted January 11, 2020 Author Share Posted January 11, 2020 Ok, All 4 wheels glued together and slathered with putty. Metal peg for the outrigger gear. Wing half with plastic bulkheads, and for a more solid wing, blobs of Bondo. The bondo is mixed and applied and before it cures the wing top is mashed down on top forming even more internal support. And finally the wing top is glued to the wing blank and assorted supports. Clamped to the table to ensure everything is straight.

Dandiego Posted January 14, 2020 Author Share Posted January 14, 2020 Port wing basic construction is finished. Lots of fine details to work on, obviously but it looks like a wing. I have inserted the metal tab between the 2 layers of the workbench and it holds just fine. I will need to bend the tab to produce a 6 degree anhedral. A quick blast of some grey primer has been applied to highlight any areas needing additional work. The large flap has just been fitted to check the fit.
