<DIV><FONT face=Arial size=2>The rule of thumb that I use in regulating is where
the jack position is after let-off. If you can regulate with spec. just use your
generic numbers and check the jack position after letoff. If it isn't in the
right place you can use keydip or blow distance to correct it.</FONT></DIV>

<DIV><FONT face=Arial size=2>Sometime ago, there was a post about how to let
the piano tell you how to regulate it, as opposed to going by the specs.
I have always used the specs and done well but I am needing to regulate a
small grand by the piano itself. I have never been taught this way but
would like to learn. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This particular piano has serious
issues. For now, I'll leave the brand out but it's a name brand.
Small grand, under 5 ft. Maybe 15 years old. Little wear.
The factory workers screwed the stretcher bar 1/4" too
low. The action was probably regulated on a bench and the hammers
had to be forced down while they crammed the action into the cavity. The
damper wires were so long, they came out the bottom of the blocks and
rubbed into the flanges below. They rang...surprise, surprise.
Nobody bothered with a quality control. </FONT><FONT face=Arial

think it went from owner to owner, but nobody fixed it. No dealer
prep...nothing. I got a good price but wish I had paid
less.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Stretcher is now properly installed and the
action actually fits into the cavity. Dampers no longer ring as I
trimmed 1/4" off the bottom of the wires and re-regulated. I am trying
to regulate the action but the back of the jack will not line up parallel with
the back of the knuckle core. The only way possible is to crank up the
capstans so high the action would never go into the piano and it would have 1"
hammer blow distance. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is this the dilemma of a compact action?
Can someone paste a link to the posts about how to regulate by letting the
piano tell you?</FONT></DIV>

<DIV><FONT face=Arial size=2>thanks in advance.</FONT></DIV>
