At the beginning of this thread I was concerned about an Estonia with tilted agraffes and uneven agraffe/string holes. It was to the point that I couldn't bend a string enough to compensate for good string/hammer mating. I have seen this on other pianos, but not this much. It would be interesting to know who makes agraffes and are the plate makers aware of the importance of a level plane (duh, probably). With the increase in our world-wide market for parts now, I wonder who makes them. The bottom line is that you cannot prep a piano to a high level without this to lay a foundation on.

The spacing of agraffes in new pianos is MUCH better in the past two to three years. I suspect the square of the holes (hence lack of cant of the agraffes) is much better, too - I haven't noticed much trouble leveling strings on the few new instruments I have serviced. They used to have Kelly drill their plates. Bad idea. All that said, perfection of hole drilling in cast iron is iffy at best. The unevenness of the material itself causes bits to chatter, at least in my experience. It's not like drilling brass.

One is the level of the agraff itself, compared to the level of the of the plate. What you claiming is that the plane of the agraff holes are not level with the plate. Which could be caused by poor drilling, or that the counter sink of the agraff hole is not flat, which will cause the agraff to cant to one side when it is tightened. The other issue is the holes in the agraff, which is what I was referrring to. Although there might be very minute differnces in the plane of the holes compared to the top of the agraff, I think the holes themselves are level. BTW, does Steinway make their own agraffs, or are they outsourced?
