[pianotech] 1880 Bechstein T. Pin layout

[Overs Pianos]

Joe,

I suspect that David is referring to the arrangement of the pins in 
only two rows, instead of the more usual four. The two row 
arrangement occasionally results in a split pin block along the lines 
of the pin rows. For those Bechsteins with an open pin block, I've 
reset the pins to a four row arrangement when replacing a pin block 
which has failed, to reduce the likelihood of another failure.

In the example shown, it will be even more prone to failure than an 
open plank version, since the non bushed plate will result in much 
more flag-polling of the pin, as a consequence of the higher coil 
height from the pin block.
