Work is done....went well and I am happy with the result.
Pic 1: I used these useful little clamps to hold the brass profiles together during soldiering.
Pic 2: 1.120kg is the weight. I hoped for some more...
Pic 3: I also redid the lower bearing for the rudder...
Pic 4&5: Before fixing it permanently to the keel.
Pic 6: I used really thick acrylic paint on the keel to get things watertight.
Pic 7&8: The paint that is coming out under the brass profile is used as paint on the hull
Pic 9: Black matte acrylic paint is used over the new part.
I must say that the additional protecting keel is making the hull much better. The wooden keel was not the right shape. So in the end it cost me a few hours work and some hard earned swiss francs to get it done.
