Before building the stern I studied several times the quite good explanations of all blog friends who already much further. Especially Uwe's detailed work that ends wih the realization that he has found a way to come to a good result. maybe someone will find another.....
Looking at the CAF build instructions, I noticed that only cradle part A9 is supposed to be enough to build the tail section.
After taking a closer look at all the individual parts and their interaction, I came to the conclusion that this should be possilble.
Set the keel into the base plate, part A9 behind it.....nasty surprise, the tolerance devil has struck.
Doesn't look good, so fill it up.
before...after...
Now prepared the individual parts, with the same realization as Uwe, the center piece will be too wide, so sand evenly.
Next, I temporarily assembled the rear part of the cradle to attach the center section of the stern to the keel using part A9.
Then I realized that laser cut part 12 is flat and not curved like parts 13-1 and 13-2. Then parts 6 and 7 would have to fit neatly and flatly in there to then insert part 13-2. This is exactly how it worked then.
Now the rest almost follows itself. Finally, the "bullhorns" are added. That was a bit tricky, but it worked well and fit.
I think I can be satisfied with the result.
