Four contact assemblies on the choir keyboard were beyond straightening.  Fortunately my friendly organ engineer had some spares.  Prising them off was easy, although nerve-wracking, as it required the judicious use of a hammer and chisel.

Having smoothed the surfaces down and got busy with the Araldite, the replacements are very firmly affixed and soldered.

Close-up of the repairs.  Slightly over-araldited, and honesty forces me to admit that it isn’t some of my best soldering, but it is electrically sound, and I won’t see it.  Although I will know it is there, and it will haunt me through every Bach chorale.
