Hi.  I'm the one that asked about welding the harp.  No, its not doing
anything unpleasant.  I just noticed the crack (which doesn't go all the
way through).  I was curious, before I sink a lot of money into the
player action, if this sucker cracked is it fixable?  I have heard of
folks throwing away pianos for cracked harps and sound boards, and
wondered why.  Now I suspect there wasn't much else good about them, and
old pianos are cheap.  Thanks for the info!
