Cutting more metal

The truss tubes provide the for/aft strength of the wing. Since these are in place now, I continue with the ailerons horns and linkages. Once those are done, I can start on the aileron and trailing edge. Then only repeat 3 more times. Funny how some of the ribs look skewed, but it’s honestly the … Read more

Making metal chips.

Finally getting the hang of producing chips in a consistent way. I think I need approx 36 pcs of the brackets you see in the second image. By the time I have those made, I’ll be an experd. These by the way are fittings for truss-tubes in the wings. Once the wings are covered nobody … Read more

How fast we goes..

Bear in mind that all these diy chips are basically old stuff. This one dates from 2012. Obviously nothing wrong with them, they are still used in a lot … Read more

(Trust me to install rainwater capture tanks, and then it does not rain for months!) Challenge of the day: I really, really want to make these small metal parts myself. Problem … Read more
