>Why do you think this is a problem in Steinways and Baldwins?

It's a personal hang up. I don't like the feel. I've also noticed that the 
loose pins tend to be the ones riding the plate. I don't think it's an 
ideal work around for not just putting in a decent block in the first 
place. And I don't see any earthly reason for Baldwin not having enlarged 
their plate holes until just last week when they have for so long been 
using concrete pinblocks that pins don't migrate in like they do in the 
Steinway block. Those blocks don't need any further support.

Yes, the newest thing in impact drivers. Now we can love the smell of 
stringing in the morning! If we just don't string ourselves in the foot. 
Might even eliminate pre-drilling altogether.

Oh, I see. Yea, it would probably work at least as fine as it does with 
Steinway. Maybe better with pin to "plate" contact right at the top of the 
block instead of at the top of the plate webbing 10mm up.
