> I am still troubled with this front rail felt thing. Is there any > rhyme or reason for a billion different sizes? They still have old die plates for presses, might as well use them? I assume these look like cardboard box formers (seems like cutters got sharpened recently). Octave spans vary a little, so do widths of sharps and natural tails. Some antique pianos use cloth strips underneath punchings, those with key upstops can use softer cloth. Having a selection is nice, I'm building a wooden rotary press to make some really tiny ones. Aren't some sold specifically for uprights? Clark
