</div>
<div>Hammer Center Height.</div>
<div><br></div>
<div>Other alignments to consider: Action spread, knuckle core to jack
center.</div>
<div><br></div>
<div>The first photo with the knuckle at 16 mm had the core lined up
properly</div>
<div>with the jack center. (Are those lead weights in the felt?)
Is that the blow distance?</div>
<div><br></div>
<div>On the relocated knuckle the jack center is too far forwards of
the knuckle core.</div>
<div>Can you increase the spread? Where does the rep lever contact the
upstop screw,</div>
<div>where does the jack contact the let off button. Is there room to
move?</div>
<div><br></div>
<div>With that height of a heel extension the magic line is out the
window.</div>
<div><br></div>
<div>More importantly in your experimentation, where does the jack end
up?</div>
<div>When all is said and done, the jack needs to be in close
proximity to the</div>
<div>knuckle at the end of the keystroke.</div>
<div><br></div>
<div>Another consideration to really confound matters: stack
relocation.</div>
<div>Since the hammers are not on, the stack could be located further
back</div>
<div>a few mm. Then the hammers might have to be installed at a
shorter radius.</div>
<div>I've corrected a few problems by moving the stack back on quite a
few actions.</div>
<div>This would cause an increase in dip and lower touchweight.</div>
<div><br></div>
<div>Fun, ain't it?</div>
