You can buy large syringes at any pharmacy. While these used to be somewhat restricted to keep them from drug addicts, now they are freely sold so drug addicts won't share needles and get AIDS. =20 =20 dp =20 David M.

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? =20 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:=20 (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.=20 (3) Remove them all. Creates an additional issue in hammer-string alignment, takes longer, but gives the greatest control over the work. =20 Thanks in advance. /Jason =20 (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.) | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | =20 Jason Kanter . piano tuning, regulation & repair jkanter@rollingball.com <mailto:jkanter@rollingball.com> . cell 425 830 1561 serving the eastside and the san juans ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
