I suspect I'm not the only one on the list who:
-thinks opening up a core-stack and repairing it is
-also thinks it would be a hell of a daunting project;
-is somewhat amazed at the dexterity and patience of the people
who originally hand-wired them at manufacture; and
-thinks pulling off a repair of a core-plane by rewiring it by
hand would give significant bragging rights. :)
But if anybody does want to, I've got a small (220x16) MDS (Fabri-Tek) core
plane with an already damaged section, cut-off edge connectors etc. to
practice on; for even more fun I could even throw in a few of two different
sizes of raw cores...
