Michael said: <br>"Hi everybody,<br>?<br>What is the better spec or way to adjust this piano action?<br>?<br>Thanks,<br>Michael Mezhinsky <span id="misspell-3" class="mark">RPT</span>"<br><br>Michael, <br>The pictures denote a <span id="misspell-4" class="mark">Brambach</span> Action. Without them, we'd not have a clue<br>and I would have answered with: With tools and specs!<G> <br>Since I own one and have several clients with them, it's familiar ground.<br>You could look it up in the Archives, as one tech would insist that you do,<br>but I'll give you the shorter route. The specs are essentially the same as<br>any other American Grand! Let-off: 1/8"-1/16"; Drop: 1/16"; Key dip: .375"<br>to .400" (after touch being the end criteria); Blow Distance: 1 3/4"; etc.<br>One other item of MAJOR consideration: The <span id="misspell-5" class="mark">Centerline</span> of the Jack should be<br>in line with the wooden point in the "knuckle", (which is built
into the<br>shank). Another is: if the leather, on the knuckle is loose, it needs to be<br>tight! That can be accomplished in two ways, Bolster with key bushing cloth<br>OR take one end of the leather loose and <span id="misspell-6" class="mark">reglue</span> it in a stretched fashion.<br>Hope that helps. Also, ...it'd be good if you purchased an action handbook,<br>for general specs of <span id="misspell-7" class="mark">alot</span> of different types of pianos. It's available from<br>the Home Office.<br>Best,<br>Joe<br><br><br>Joe Garrett, R.P.T.<br>Captain of the Tool Police<br>Squares R I<br>http://gpianoworks.com/<br><br><br><br> </div> </div> </div></body></html>
