The only trick that works is making as= little change as possible which means it has to be at pitch and= in the ballpark. That may take awhile. Lubricating centers is a 5 minute job. Why would you consider= making it complex? Everything evaporates except the lube in= the bushing cloth. No matter how carefully you were to apply it= you're still going to get it on the wood... David I. Original message From: jason kanter To: Pianotech Received: Sun, 27 Feb 2005 10:50:55 -0800 Subject: which lubes? Couple of questions have arisen for me. Steinway upright, 1883, 20 cent pitch raise. In the high treble,= I had an awful time getting the tension to move across the= pressure bars. Pull, pound, pull, pound, pull, whack - no= movement - gently pull a little more - string suddenly goes to 5= cents sharp. Lower, whack, lower, whack - no movement south -= suddenly the string is 5 cents flat. Sigh. Pull, pull, etc.= What's the best lube for the region of the string between the= pin and the speaking length? The other situation is grand hammer flanges. WHen they need some= alcohol or some Protek lube or whatever, what's the neatest way= to apply the liquid without sacrificing effectiveness? Choices= I've tried are: (1) Spray from 1", left to right at an angle and right to left at= an angle, basically thereby soaking the whole flange in liquid= and getting the bushings wet. Messy. Not particularly= efficient. (2) Remove every other hammer/flange. Treat the removed ones over= a towel, putting a few drops on each bushing and working the= flange back and forth. Treat the others still attached to the= action, tipping the action up on end, putting a few drops on= each bushing, tipping the action the other way and repeating.= Then replace all the removed hammer flanges. The hammer-string= alignment is preserved by the hammers that were not removed.= This is time-consuming, and seems inherently uneven because the= flanges that are removed get slightly different treatment from= those that are not removed. (3) Remove them all. Creates an additional issue in hammer-string= alignment, takes longer, but gives the greatest control over the= work. Thanks in advance. /Jason (ps. I am embarrassed to admit that when I was apprenticed in= 1970-71 to Sheldon Smith, the technique I learned was to slather= everything with WD-40. This was my first introduction to WD-40= and Sheldon obviously thought it was great stuff. I am sure he= abandoned that practice upon revisiting some of these poor= pianos.) | | | | | | | | | | | | | | | | | | | | | | | |= | | | | | | | | Jason Kanter . piano tuning, regulation & repair jkanter@rollingball.com .. cell 425 830 1561 serving the eastside and the san juans ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
