Jamming is between hammer flange screws and pin block. I don't think much of anything has ever been done with this piano. The hammers are as hard as can be. Really bad sound for such a nice sized instrument. >Certainly, as suggested, you should raise the glide bolts (assuming it has >such), thus lowering the action height.

I will get out to the shop later this afternoon. While that job is not on the docket for today I think I can manage that much work on it. I will let you know about the string heights as now you've got me curious as well. > You'd want to take more than the usual "first and last of each section" > samples. Is the bottom of the pinblock equally curved? It seems as though the pin block is equally curved as that was the first thing I noticed on the Miller. I assumed the pin block was de-laminating in the center. After encountering the Samick product where I could actually remove the stretcher and see the whole picture I stretched the string across the top of the plate on the Miller and found the warp on that piano. Both the Samick and the Miller have bowed pin blocks that are touching (jamming down on) hammer flange screws. I will first explore removing the action and then these other items and report back. Thanks for your help and additional ideas! >Good luck - > >David Skolnik >regards, >>Greg >> >>Greg Newell >>Greg's piano Forté >>mailto:gnewell@ameritech.net
