Joe,<div>I don't have answers to your annealing question but you might consider calling Jude Reveley for information on how he redesigned a couple Chickering actions: WN&G action rail, WN&G action parts, back action, and a new and redesigned keyboard. Probably more than you were planning on, but perhaps worth considering. If it's the same model Jude has done all the design work on maybe you could work out a deal . . .</div>
