The wet-rag-and-iron technique must work, or it wouldn't have been suggested. But when they bend wood for piano rims, bentwood rockers, and so forth, don't they use a lot of steam and gradual pressure? That's what caused my burned-up-key disaster-I was trying to steam it for a long time over boiling water (left the pan for a "minute" to run down to the shop, got busy, was reminded of my project by the smoke detector!) Anyway, has anyone tried putting the key in an autoclave or some other really steamy environment, then putting the twist to it?
