List.. Bumped into something "new" today.. so I thought I would put it forward in the form of a quiz. Piano... August Førster... about 20 years old. Symptom..... Blubering on soft play reported by the owner. In addition my own feeling of a kind of "heavyish" feel to the action. Conditions: Letoff was at 1.5 mm - 2.5 mm, checking was well within acceptable parameters, key dip was 10 mm and this was way more then enough for jack clearence under the knuckel. No lost motion yet jacks easily slipped under the knuckle on release. Dampers... newly regulated and in fine shape. Jack stop rail adjusted for plenty of clearence. Keys level and at factory specified height. In spite of this seemingly fine situation there were about 30 keys that were blubering on soft play. Took me a few minutes dinking around to figure it out, and I am sure I have seen this exact problem before without solving it.. but this time I got it right and I was really a bit suprised at the dramatic results. Blubering completely dissapeared and the "heavyish" feel to the action was totally relieved. Good hunting... Answer tommorrow. grin -- Richard Brekne Associate PTG, N.P.T.F. Bergen, Norway
