[CAUT] Interesting

[Paul T Williams]

Hi Alan

I post back and forth on each area of the site to get the most feed back 
from techs who use the new list, and those who email.  (I prefer the old 
way, in case my vote makes a voice)  Yes,  after some research, I'm going 
to try the TouchRail system with this Petrof.  First, I'm trying on a 70's 
Steinway B that is horrible in a piano prof studio. 

I'll see what I have after going through this Petrof.  Huge hammers.  I'm 
sure I can reduce a lot of weight there. Upon more investigation, nasty 
tight action centers, oversnug key bushings and swollen key balance holes, 
and keypins in desparate need of polishing!.  That will have a lot to say 
when i'm done. 

Me thinks that class about the new site at KC is going to be packed!!  Eh?

thanks!
 

PAUL

Hi Paul,

I’m not sure why you posted to this old list but I saw your post. I echo 
David’s thoughts on turbo wips as well as the suggestion that you take 
care of friction first. The only thing I would add is that before I used 
turbo wips, if I still had a piano that had too much lead and was still 
heavy, and budget were limited, I would go with Scott Jones’s Touchrail. I 
don’t think there is a downside to these. The cost is very reasonable, 
installation is fast, installation is reversible and their use can be 
customized and flexible. If you haven’t explored these, see Scott at the 
convention at his booth (I’m assuming he’ll be there).

I’m not a fan of turbo wippens if they can be avoided.  All of those 
1970’s pianos will require a switch to 17 mm knuckles when replacing parts 
(at least I haven’t met one that didn’t so far).  Sometimes a capstan move 
is required as well.  There was a between period after they went to the 
accelerated action but kept the 16 (or 15.5!) mm knuckle position and it 
was pretty much a disaster with 7 or 8 leads in the lower part of the 
piano and high touch weights as you report along with high inertia.  Nasty 
things to play in spite of the adaptability of most pianists.  
 
Once you are able to determine the match for leverage and hammer weight 
you’ll likely be able to avoid the turbo wippens.  Look for someone who is 
teaching Stanwood methodology in KC.   It’s really the most direct method 
of analyzing this stuff but a grounding in action analysis the “old” way 
is also a good foundation as it tells you much about how the action will 
regulate.

thanks, David.  I'll be taking those classes! Do you like the turbo wips? 
It helped some on one of the other prof's 70's steinway B....  I just 
don't like the $850 for them if I can help it.

You can’t make decisions about moving capstans until you know how friction 
is contributing to your problem.  You shouldn’t make decisions about 
replacing parts without an analysis of the action leverage and the weight 
of the component parts.   If the action was heavy with lots of lead before 
and you use the same specs to replace the parts why would you expect 
anything different?  DW by itself won’t tell you much, you have to check 
the upweight as well.  Not sure where to start but I wouldn’t look to 
center pin lubricants to solve your problems generally.   Kansas City is 
offering some good classes on this very subject.  Good place to start.

Mick and all. 

I asked Mick about heavy DW on a '79 Steinway B.  I just replaced all 
hammers and shanks with S&S parts that weighed out the same as the old 
ones...just a little heavier since the old ones had been filed a few 
times. (I call this Ham-shanks when making notes) 

Before DW was over 60g in the bass, and high 50's in the treble.  Lots of 
lead in the keys. Ugh! (thinking about moving the capstans) 

Just for fun, before I left for a couple hours, I McLubed the wippen 
action centers.  When I came back, the samples I juiced did indeed come 
down about 10g!!  I'm sure it's just a short term fix, but wondered if 
yall have tried this?
