[pianotech] Retrofitting a Steinway w/adjustable back action

[David Love]

I've usually used action cloth in this application but sometimes I use the
tray felt that comes with the Renner kit if I've ordered it and if it's not
too thick.  With the capstans that I used to use sometimes that felt was a
bit too thick so I got to using thin action cloth.  With the hex screws and
their lower profile I would probably go back to using the Renner tray felt.
Anyway, mostly the movement is lifting so there's not much worry about
rubbing noise. 

I got the screws from R.J. Leahy (www.rjleahy.com) which is also my source
for brass half-rounds and half-ovals.  It's a local San Francisco metal
products dealer.  They do ship but I'm sure you can get the same screws from
McMaster Carr.  The SS screws are $.07 ea.  So $4.00 worth of screws.  Much
better than the $40.00 for a set of capstans.

Nice, David!

Is that the white woven action cloth? Any rubbing noise? Where did you buy 
the SS hex screws, MSC, Mcmaster?

Ron,

One pictured seemed to show that you knocked the edges off the zinc hex 
screw. That seems like a good idea, but what about rust? Did you put a 
finish on?
