    What took you so long? No idea.. More then 10 years ago I got myself a CNC-router with the idea that I would be able to metal metal parts. I’ve used it up to now mostly for non-metal parts. But retirement has given me enough time to finally sort things out. That and a better…

    After glueing the trailing edge wood (not shaped to final yet!) it was time to do a bit of tube-bending. It’s 4 mm tube, and for the life of me, I don’t know why it is so soft. Almost feels like copper tubing. Never mind, just try to match the shape. Trying to hold the…

    There is no reason for the pics, it’s just nice weather and it looks great 😉 Weight as you see it here is 1850 grams. Of course I took it to our end of season do, just to show off.

    Closeups of my handywork. After sandblasting I ‘ll reheat the joints to make them flow a bit more and fill any voids leftover. This will be for cosmetical reasons only.

    Just a relative quick job tonight: making the fin. The only noteworthy item would be that after installing the ribs, I still had to drill a hole for the bracing rods. I decided to simply cut a slit with the Dremel and enlarge it to fit the tube. Seems to work well, and since it…

    Once it is all finished it looks easy. At the start it’s more like ‘how am I going to tackle this? I decided to use a 3 mm alu plate as a mount for the short tubes that hold everything together. This way I could mount some 5 mm wire studs to hold the motor,…

    It fits, no worries there! It’s gonna be jus’ perfect! I am sure I can’t resist building the engine mount next. It might not be the correct size, because depending on the CG I will move the engine forward/back. But it will be a good exercise, and it makes things look real..

    It’s never too early to add that famous mark. Of course this is the full size one, and I might not like it, but it is a good enough place to start! Probably overpowers the plane, but it has the right sound, and I have seen the engine long enough in use to know it…

    Last year I had some fine nice sand left over from doing some garden-diy-ing. ‘Just in case’ I stored it in a nice dry place, knowing that one day, dry sand would come in handy. I knew from the onset that I needed to find a way to clean up my brazed parts. Up to…

    After a few weeks of putting bits of tubing together, I am at the point where things start to look like something you would recognize as a fuselage. This morning I cleaned up the fuse with a diy sandblaster, much to my surprise this went really well. It’s the usual bucket of dry sand, empty…
