I copied these regulating instructions for a Bluthner = Patent Action from the web page of Barrie Heaton PGP (I think). I hope = this helps. Good luck!  :-)   I love reading your posts. I can hear = your Scandinavian accent!</P> <P> </P> <P>The necessary operations must be carried out strictly in the = following <BR>order. The fitting of the BLUTHNER-action is based on a touch-depth = of 9 <BR>mm and on a hammer-blow of 45 mm.<BR><BR>1. The hammer-flange screws = should be tightened.<BR>The hammer-heads must then be spaced exactly on the strings.<BR><BR>2. Setting-up. The jack must be so adjusted, by means of = the carriage <BR>which is screwed on to the key, that it drops quite easily = under the <BR>nose of the abstract. The guide-pin of the abstract must be = straight and <BR>vertical<BR><BR>3. Let-off. The hammers should release 1,3 mm from = the steel strings and <BR>half string thickness from the bass strings? The set-off = screws for this <BR>adjustment are situated on the hammer rest rail.<BR><BR>4. = Touch. Contrary to the ERARD action, the touch is made quite firm. <BR>The key = is depressed slowly on to the touch-baize, after which the <BR>hammer = should continue to rise 1 mm, till it releases, so that it checks <BR>only on = striking the key strongly. (No after-touch).<BR><BR>5. Checks. The checks should = be adjusted at a slightly greater angle <BR>than on the ERARD action. The = check point is 24 mm above the normal <BR>hammer tail line.<BR><BR>6. Drop. = The right-angled repetition spring which controls the drop <BR>should have a = thickness of 0,85 mm in treble, 0,95 mm in the middle <BR>range and 1 mm = in the bass; the guide pin of the abstract must move <BR>easily in the bridge = leathers so that the abstract drops of its own <BR>weight. The repetition springs = must move freely in the abstract felt <BR>clips and by pressure of either = side of the right-angle spring, the drop <BR>is controlled. The hammer head should = release 3 mm from the steel <BR>strings.<BR><BR>7, It is now necessary again to = check the touch throughout.<BR><BR>8. The dampers should lift when the keys are = half depressed.<BR><BR>9. The damper shade-rail must be adjusted in such a = way that when <BR>depressing the sharps, is very little play.<BR><BR>10. The = coiled spring which is attached to the abstract should in the <BR>normal = position of the key not rest on the jack, but remain about 3 mm <BR>from it. An even = touch is of the greatest importance.<BR><BR></P> <P>Bluthner-patented action<BR><BR>1. Hammer flange screw<BR>2. = Whippen<BR>3. jack<BR>4. Abstract<BR>5. Hammer shank<BR>6.
