I only had the piano for a couple of months, and used it for practice when I was learning to tune, so I can't comment from experience what the tuning stability was like. From an engineering standpoint, aluminum expands and contracts a lot more than cast iron, so I would assume that it made tuning stability worse. But really, if it was such a great idea, wouldn't everyone else have used it, too?

| Yep, it sure does - an ENTIRELY different COE than cast iron - which is why iron block engines with alluminim heads are such a monumentally BAD idea, not to mention the dis-similar metals problems. Such effects can be minimized, but certainly not eliminated by correct selecton of alloys and correct design of the casting, shape, size, bracing, etc. How it might be done with a piano harp, I dunno! Yea, I agree that if it had been a good idea, others would have followed. But then again, look at screw stringers - the engineer in me loves the idea - why didn't THOSE catch on? Oh well. Rontuner - I love that music box piano - I forget what those large disk players are called, but I love their sound.
