[CAUT] Damper guide rail holes

[Paul T Williams]

I thought I said that.Ooops! Geometry goof!  Anyway  Pi are not square, pi 
are round! Cornbread r square! lol :>)

Sorry...it's been a long day,

Paul

Circumference is pi x d (or 2 pi r). 

pi r squared is area.

Jeff, 

Ken Sloane at Oberlin at the Steinway seminar had us make a new guide rail 
from scratch two years ago.  My project was also a B. We used a #15 drill 
bit for the main hole, then also put a counter sink hole on both sides for 
the felt to open up on both sides.  We used no glue to install, just pull 
them through and trim up to look good. Then just used the pi-r-square to 
figure the radius for cutting the right felt width. I think 5/8" was about 
right.  I think all the Steinway guides have the same damper wire widths. 

Hope this helps 

Paul

Hi List,

Anyone know what size drill bit to use for drilling new damper wire guide 
rail holes for a Steinway B? Or where to find out?

Thanks,
Jeff Farris
