Why does this archaic practice persist to this day? This belongs up on the museum shelf right next to the process of putting little pieces of paper under the keys to level them. Why not just drill through the plate flange and have an agraffe with a shank long enough to accept a nut on the other side of the flange? No removing and reinstalling. All the agraffes come out at the same height. And while you're at it you could build in an alignment device that's machined into the plate (such as a woodruff key, a flat on the threaded shank, small drilled hole that mates to a pin on the agraffe flange, etc.), so your alignment wouldn't be based on the eyesight (and level of frustration after some period of time putting in agraffes) of the installer?
