Thank you, TIMTAPE. That PDF is very helpful, and the process appears understandable.

As far as this head goes, is the brass tripod screwed over the coils, with the hole to attach the head cover, part of the re-lapping process or do I remove it? I imagine the procedure is to sand down the whole of that front brass curved surface, but it's as well to check!

Does the square (erase?) head need the same treatment, and if so does it need removing from its alloy case?
