[CAUT] Action spread

[Paul T Williams]

That's exactly how I line up the knukle jack relationship. back of the 
knuckle core with the jack.  Too far forward and you get the "cheating" 
jacks.  Too far back, and the touch gets a little heavier and aftertouch 
is compromised.  I really don't want to move the stack.  Or move the 
capstans unless absolutely needed.  But, the DW is well over 55g in the 
mid-section on up, 60+g in the bass, and nothing really gets any better. 
The back action is also really heavy "to the touch" but can't justify 
spending more on this thing since it's just a practice piano, yet I want 
the instrument to be pleasant for the student.

How much can one move an action one way or another, back or forward to get 
a better geometry.  The "line" of the relationship to the wippen-flange, 
capstan and balance rail on my particular M&H is actually quite good. 
Perhaps I put too heavy of hammers on it! ?  I'm not sure yet until diving 
in further...This piano has the tilted capstan issue from the '20's, so 
perhaps that part of the problem on this A.  Would "modernizing" the 
capstans to upright be a good thought?

I'm just starting the re-stinging part, so can't do too much with the 
action as it sits.  Man...I'm not a fan of restringing a M&H....one single 
string...then one double...then one single string, then one double.  It's 
a lot of time!!! I'd rather have the single strings all the way! :>) (or 
double..."normal" way with just a couple of singles)  Hitch-pin loop knots 
on 20g wire is nasty!!  I'll think twice before I take on the one piano 
next door!! :>)

I really didn't wish a huge project, but now fear the worst.

Thanks for all the input.

Paul

Hmm, I'll take a look at that. In my mind's eye, it sounds the same as 
what I was suggesting, but might be more precise. Thanks.

I know what you are trying to say, but is this unclear? Generally, don't 
we
 want the back of the jack to line up with the back of the spline of the 
knuckle? 
 
But  optimally you want the core
of the knuckle to line up with the jack center  at rest.

Knuckle core to align with the jack center pin.
