[CAUT] WAPIN INSTALLATION: LIVE!

[Tim Coates]

Jim,

No there is not.  Although the Journal article from quite a while back 
had a picture of the two pin configuration.

Occasionally a two pin configuration is needed on a few notes on 
Baldwin grands.  There isn't enough room for the trapping pin.

You are correct that the three pin configuration is THE standard.  And 
for reasons stated below.  Although we are finding salesman like the 
trapping pin.  It gives them something to show a client.  "This is why 
this little piano sounds so big".  Unlike a bass string rescale, there 
is something to easily look at.  It makes a difference on the sales 
floor.
