[pianotech] Reducing tuning time (was Re: frustrated)

[Dale Erwin]

Yes Jerry it is called action cloth. Its for sticker/ abstract felting,wippen heels....ahhh you know that.
 I use the thick stuff from Schaff. I've use this material for mutes for about 30 years. 
   I strip the material in 1/2 inch or so pieces and hot glue the  ends together  so I have on continuous piece.
  The more worn pieces I use in the high treble and the newer thicker pieces in the bass and tenor.

If you get the red felt from Schaff it can be to thick.  Used to be you could 
specify medium, medium thick.. I usually got medium.  Then upon Bill Bremmers 
recommendation, I started purchasing action rail cloth.  I love it!!  It's just 
about the same size thickness wise but, skinner than the red muting felt.  

Am I calling it by the right name guys?  You that use it know what I'm talking 
about but I'm not positive that I'm using the correct terminology for it cause 
it's been a while and it.  The stuff seems to last forever.  

You order it like one solid piece, something like 72" or 84" long or so, and cut 
to desired length or, don't cut it at all.  I ordered 6 or 10 of them so I could 
experiment with it.  I wound up cutting one of them down the center all the way 
and using that one in the treble.  I also use it to shim things.  I often use 
that one in the tenor too because the hammers or dampers won't get in the way 
then.  It works good.  :)  

I use the full sized ones on grands and quite often because of the spacing, I 
use the red felt on verticals.  It really just depends on the piano and how much 
room there is between the strings or between the hammers and dampers.  I don't 
now why but string spacing tends to be a little greater in the tenor on 
verticals than in the treble.  

I have also tapered by trimming, the felt down in the very upper tenor about the 
last 8 notes or so, section so it wouldn't interfere with the dampers.  That way 
you can shove the felt up higher and out of the way or, lower out of the way.  
I've put them under the dampers before too but you'll have to be careful doing 
this.  You'll want to push the sustain pedal down and if there isn't enough room 
for the felt to slide easily behind the dampers, lift them two or three at a 
time and slide the felt behind them.  I rarely have to do this and in fact, 
prefer not to due to too much ringing coming through in that area.

Thanks, this is all great advice.

Now - what are the tricks to strip mute ?

When I first started, I tried to strip mute and could never get enough space in 
the loops and the felt seemed too thick.

Also, since most of mine are uprights, it seems the traditional strip mute is 
too wide for the upper notes (either the 
dampers are in the way or the hammers are blocks)

There must be a special technique for getting the right size loop - and - 
getting the right size mute felt so the above 
does not happen.

Would thick key bushing cloth work ? (I have a whole roll of that - used in 
various places for player work)
