The spare parts for the engine hopefully will arrive somewhere next week. In the meantime there is still a lot of detail to be made. One of them is scratch building the rudder and elevator control horns. Bo explains to make them out of 0,1mm brass sheet (it says 1,0mm, but that's a mistake)
So first for every control horn three strips of brass where made:
The smaller part is sandwiched between the two larger parts. This way you should be able to fit an eyelet in between. I have soldered the three parts together and filed them into the correct shape:
The two larger ones are for the elevator and the smaller for the rudder. Then holes have to be drilled into these horns. This is a little bit fiddly because at the end this should be done with a 0,2mm drill and I don't dare doing that by hand. So I put them in my milling machine and drilled the holes. Unfortunately one of the three control horns were dropped on the floor and has disappeared now. Tomorrow I will try to find it, or make a new horn.
In the middle of the horn a larger hole is drilled.
And this is where these horns are going to find their final destination:
