This message went to "one recipient - " by mistake -- so here it is to all. Combination answer (to all damper "oink", "jup", ("Juhn"), and other--name noises. I found that most of them are by far in the "flat" damper area. That includes the 1/2 and 1/2 kind in the tenor section. Peeling works well on flats, not so well on stiched flats (but it can be done). Sanding LIGHTLY on all of them. For those who are interested, Judith Palmer of Bala Cynwyd, PA, (215) 667-9567 makes a tool for filing all kinds. (I get no commissions!). "Shaking" dampers are a horse from a different garage -- the guide rail bushings must be done first, then -- the dampers may not shake and make no "oinking" "juping" or any-th-ing noises. Ernie Juhn
