First I'd ever seen or even heard of? (We live a sheltered life, here in the boondocks, i.e., the Ozarks.) Pretty case, has potential I think, but regulation is horrible (see horror story below) and it badly needs voicing after that. Meat of Message (pork, mostly):  Does anyone out there have a set of reg specs for this piano or know where I could reasonable get them? Horror story, the worst note: F5 blocking against the strings "chingank" sort of sound. Found the lettoff button screwed to the top, no letoff at all. "Who would do this," I ask, "and why?" Tried to set a letoff, but the hammer failed to reset on every blow, i.e., dead note, no play. Hmmm ... Further investigation finds the jack way too high, about 3 mm above the rep window. No wonder someone who couldn't/didn't diagnose the problem correctly messed with the letoff trying to get it to reset--I'm surprised he/she left the front rail punchings in place! Adjusted jack height and all is well—or at least the note plays, lets off, and resets. The only excuse I can give our mystery tuner is that who the heck would expect a key regulation item to be so far out of whack? And why would it? Given the piano's one-owner history, it almost had to come from the factory or dealer this way.

I had a small church acquire a Hyundai Grand, they were made by Samick about 12 to 20 years ago. The one I work on has the Samick numbers stamped on the action SG-155</div> <div>which referred to their 5'2" grand. Anyway if you find the number on the action you can use the corresponding regulation specs for the Samick of whatever the number. If not just measure it and find the Samick of the same size and use those specs. </div> <div>About the loose pins in the block, do the coils look to be a little higher from the plate than normal? I noticed they looked that way in the one I do. I figured at some point I would probably have to drive them, right now they seem tight enough, I just have to watch my hammer technique and not get lazy or flagpoling can be a problem. </div> <div> </div> <div>If your tuning pins are loose and you have the room, you might want to drive them. I'm not positive but I'm pretty sure that's a Delignet block in that piano, Samick used them a lot back then. I don't believe the Delignet blocks respond to humidifiers as well as other type blocks but that's just what I've been told, I have no personal experience to that effect. Not that a Dampp-Chaser wouldn't help, just if the pins are that loose perhaps driving might help more. The D-C would help with sounding board, action, etc.  Mike -- Never become so much of an expert that you stop gaining expertise.
