The CPL doesn't have any objectionable odors and is always in my toolcase anyway. Using a hypodermic syringe with about a 20 guage needle, less than one ml (milliliter or cc) is enough for the entire piano (a small droplet on each string). I don't know if either Liquid Wrench or CPL would have any long-term negative effects, but on older or lower quality uprights, or rusty strings I prefer to not break strings. Pitch raised a 1972 Cabaret Player 150cents last week, and a 1914 Newton player 250 cents (hadn't been tuned in 70 years) yesterday using CPL and no problems (so far). Last time I spliced a string was in a local high school; the music teacher walked into the room at the wrong instant, I flinched and the blood flew a couple inches. Maybe the guild should create conditions like that for tieing the knot during bench exams! Fred Scoles, RPT, Syr. Chapter 131
