I'm glad you enjoy the photos, makes it worthwhile to keep you posted.
@ Rudeboy,
Thanks for the photos! It makes it all clear to me. I'm changing my plans and use a single ball-link. Since I don't have much experience with silver soldering I'm going to ask some people at my club to help me. I will try to build in the assembly without cutting a gap in the fuse side, but I'm not sure if this will work out well. We'll see. I always could cut a gap afterwards if it isn't working without.
