You might have a warped rest rail.<o:p></o:p> >From square one ,<o:p></o:p> Establish natural key height to three criteria . 1 .Set height on C-40,D42 below the fallboard-fall strip so the top of the key has clearance and does not hit . 2. The front key pin is inside the key bushing mortise . 3. The bottom of the key front at rest is not above the top of the keyslip .Satisfy these three things and make it look “right” <o:p></o:p> Then set dip , blow and letoff that results in acceptable aftertouch, You can see 1/8th or whatever letoff dimension you prefer (I wouldn’t go less than 1/8th on this piano to avoid blocking hammers down the road.) <o:p></o:p> I then adjust sharp height-dip on c# 41 also by visual criteria. Start with height that looks correct above the natural .That is the keystick is not showing above the naturals. Set dip so the sharp is not buried below the naturals .Check the travel of the back of the key with the sharp and both naturals on either side.<o:p></o:p> The sharp capstan MUST rise the same distance as the natural capstans.<o:p></o:p> Adjust the sharp height -dip combination as necessary to achieve this. Give a little ,take a little, but make sure the sharp looks right over the naturals and does not bury below the naturals. At this point I break my rule and check sharp height with a scale. It will be on either side of ½ inch +/- a scosh.<o:p></o:p> If the capstans rise equal on all keys and the blow- letoff is consistent ,after touch HAS to be consistent.<o:p></o:p> A dead give away when this is wrong will be in the backcheck position. I’m not one to agonize over some inconsistency in back check position on low end verticals, but you will see the backchecks for the sharps WAY out of line with those of the naturals with inconsistent capstan rise.<o:p></o:p> My point about measuring is that you can follow all the suggested dimensions from the manufacturer and the thing won’t work .I.E. see that sticker on the inside of late model Kimball’s <o:p></o:p> Understand the process and all you need is a dip block(s).The piano will tell you what to do.<o:p></o:p> <o:p> </o:p> Tom Driscoll RPT<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> </div> <blockquote style='border:none;border-left:solid blue 1.5pt;padding:0in 0in 0in 4.0pt; margin-left:3.75pt;margin-top:5.0pt;margin-right:0in;margin-bottom:5.0pt'> <div> I'm working on a <st1:place w:st="on">Baldwin</st1:place> console.  The plate has 40 stamped on it.  It's a pretty good piano and is about to go back to its home.  The action is a little on the small side .The regulation is pretty good but I am needing more aftertouch.  <o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> Key height is 2 1/2" above the keybed.<o:p></o:p> </div> <div> Hammer Blow distance is 1 3/4" to strings.<o:p></o:p> </div> <div> Letoff is about 1/8" in the treble and 1/4" in the bass.<o:p></o:p> </div> <div> The bass and midrange white keys are pretty good with correct aftertouch.  Some of the whites in the higher treble have shallow aftertouch.  <o:p></o:p> </div> <div> Sharps have little aftertouch and are terrible.  They sit 13mm above the whites.<o:p></o:p> </div> <div> There is nothing obviously wrong such as too many punchings under the keys. This piano does not appear to have been tinkered on by an unqualified toooooner.  <o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> My choices are:<o:p></o:p> </div> <ol start=1 type=1> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Raise keys.  <o:p></o:p></li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Decrease hammer blow distance.  <o:p></o:p></li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Increase letoff. <o:p></o:p></li> <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; mso-list:l0 level1 lfo1'>Increase dip.<o:p></o:p></li> </ol> <div> With choice 1, I'm hesitant to do this as the keys are right up against the rail.  With choices 2 & 3, I feel like I'm losing power.  With choice 4, I feel like I'm chasing symptoms and not the real problem.  <o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> It may be that the action is compact enough that I just need to squeeze what little I can from all 4 choices.<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> Any thoughts from the list?  Am I overlooking something?  Thanks in advance and happy holidays to all of you.<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> Ron Shiflet  <o:p></o:p> </div> </blockquote> </div> </body> </html>
