You mentioned that the treble hammers are catching on the plate. There usually is some adjustment in the placement of the action. Often very little adjustment is needed to free them up. Only question is, does that adjustment improve the sound up there, better strike-point, or not? I'm not familier with this brand & make. A lot of pianos have guide pins on the action that go into the cheek-blocks and some sort of adjustment mechanism in the cheek-blocks. You can remove the cheek-blocks and keyslip and slide the action in and out a little and find the sweet-spot or the not-so-sweet compromise. Most likely you would need to fine tune this after filing/shaping/whatever the hammers to reduce their strike-zone to something a lot more musical. Sounds like a lot of fun. Andrew
