Hello Tobias,
I'm having a question for the taper on the sternson knee.
Isn't it just one flat surface which can be milled by underlaying some part with the proper height?
You are doing two different milling cuts (yellow and red in your picture). Why are these two steps needed? I can't see the different angles in the drawings.
And sorry for keeping you busy by asking so many questions.
You have two different lengths of the parts to be milled and the standing part is not completely beveled. I must add, however, that I milled it in the assembled state. If you mill them individually it will certainly be different. As I mentioned earlier today in Splitter's Log, there will be different approaches and mine may not always be the best.
