Thanks a lot my friends!!!!
This time I will fix the keel to the working piece of table top. I also doublechecked the right angle of it.
Then it was time to glue the stern part to the keel.
I made a picture of the "old" hull and the keel of the new one. The new one is very big!!!!
This time I used metalangles which where screwed into the tabletop. I also used a M3 screw to fix the stern securely.
The stern is also fixed with a M3 screw. I can unscrew to front and the back screw and lift the keel from the tabletop.
I used leftover cheap plywood to quickly make one frame. Just for the fun of it!!! The frame is around 30cm wide ....
Overall view of today work ....
