If you can raise the keys slightly (shim under the balance rail), you'll get enough key travel for jack escapement and aftertouch. Almost all "bobbling hammers" are the result of too little or no aftertouch due to settling of the keys at the balance rail. Generally, though, it's in the middle of the piano where it is most played. Hmmm.<FONT face="Arial, Helvetica, sans-serif"> You'll then, however, have to adjust dip, lost motion, and checking again.

Then your problems (bobbling hammers/heavy touch) are probably due to too-strong hammer and/or damper springs...and it also could be too-soon damper lift. Also checking the height of the balance hole with a balance hole reamer would be in order. OK, check for too-tight balance holes and bushings, too. <BR> <BR>Barbara Richmond, RPT <BR>near Peoria, IL <BR> <BR>----- Original Message ----- From: "Farrell" <<A href="mailto:mfarrel2@tampabay.rr.com">mfarrel2@tampabay.rr.com</A>> <BR>To: <<A href="mailto:megdanmak@sbcglobal.net">megdanmak@sbcglobal.net</A>>; "Pianotech List" <<A href="mailto:pianotech@ptg.org">pianotech@ptg.org</A>> <BR>Sent: Monday, June 16, 2008 3:41 PM <BR>Subject: Re: set letoff to get acceptable aftertouch? <BR> <BR>>> would any of you ever set letoff far away enough from <BR>>> the strings to get acceptable aftertouch, if nothing <BR>>> else seems to be working? <BR>> <BR>> No. <BR>> <BR>>> it's a crappy piano, a <BR>>> bradbury console. i'm need to get an acceptable <BR>>> regulation, but nothing more. <BR>>> <BR>>> i've tried playing with strike distance and dip and <BR>>> can't seem to get good enough aftertough in a small <BR>>> section of the bass (perhaps two and a half octaves) <BR>>> to avoid bobbling. <BR>> <BR>> You should be able to remove punchings at the front rail pin or even use a > thinner felt punching. <BR>> <BR>>> also the dip is about 12 mm. is it <BR>>> a sin to go deeper to get acceptable aftertouch? i <BR>>> don't remember hearing anyone mentioning keydip that <BR>>> deep. <BR>> <BR>> Yes, mortal sin.
