Glueing the shafts.
To get the shafts on the right distance during glueing I made a distance-plate.
The holes for the ruders are also drilled and the shafts of the ruders were glueed together with the shafts. Everthing is glueed with a 2-component glue with a curing time of 24 hours, this gives you enough time to fix everthing on the right place
