[CAUT] Down Weight Too High With New Hammers

[Jerry Cohen]

I just measured a B from 1968. The BR pins are slanted back between 1.5 and 2.5 
deg.
Also, Chad Frye, former parts manager once told me that the holes were drilled 
on an angle to match the angle of the balance rail pins.

Curious. Are Steinway balance pins installed at a 3 degree angle? I haven't 
noticed, but I also haven't checked. I _have_ noticed on occasion that the holes 
in some of the half rounds weren't square, which is why reversing them would 
change key level. But I hadn't noticed a consistent pattern. I assumed it was 
just inconsistency in manufacture.
