[CAUT] Strange capstan reconfiguration.

[Paul T Williams]

Yea, you're probably right. I forgot about the tilted capstans, Was '34 or 
'36 when they stopped that? On with the "accelerated" action? But 7mm 
seems extremely too far back.

My guess is the originals were angled. The new capstans at 90 degrees 
would then be close to the originals in where they contact the wipp heels. 
Probably moved back at most only a couple mm. I just did something 
similar, so this looks very familiar to me.

Hi All, 

I pulled an action from one of our piano faculty's Steinway B's yesterday 
since it's just "not working" right.  Besides the standard hammer 
reshaping, rebusing the keys, regulation issues etc., I found that the 
capstans had been moved BACK some 7mm back and then turbo Renner wippens 
installed. I'm wondering why?  Wouldn't moving capstans back make the 
action heavier?  To "fix" this, would the turbo wippens make up for this 
in a way.  Why mess with what was there?  This is a Steinway B from the 
20's. I failed to check the geometry "line" before moving the action to my 
shop.  Why, you might ask?  Our elevator died and will not be fixed until 
mid-June, and the Special Olympics will be here in July, so I hope they'll 
be on time for the fix. I had to take the stack down the stairs on one 
trip and then the keyboard on a second trip. What fun this is! I'll soon 
check out the geometry line next week and put them back together, but want 
to get onto the key rebusing project soon.  All else is "normal". It plays 
like a truck, but I found the blow distance at 1 -7/8" instead of 1-3/4" 
and the jacks are waaay too far under the jacks, so that will help a bunch 
fixing that. The key height and dip are perfect. 

What is going on with the capstan reconfiguration?  All thoughts welcome.
