I have a problem with the ruderkopf. As you can see on the picture there are several cracks. I am afraid of welding it, because it might crack again. Is this a well known problem? Can somebody tell me what to do?
I had a similar problem. It was solved by welding a U-shaped pieces of stainless steel (Nirosta) onto both sides of the "Ruderkopf". No more instability since then.
