[pianotech] sluggish (was no subject)

[Matthew Todd]

Do most Wurlitzer consoles have weights in their keys to begin with?  The reason I ask is because the piano in question does not.

If we free it up and it works, that means then the key weights in the fronts
do not need attention or addtions to the rear of the key. If a person wants
to go through and re-pin that's fine too.  But, like I and others have said,
I've been able to clear up all of the problems without re-weighting.
Eliminating the problem, not the symptom is the resolution.

And I think it's just the opposite. Just because lubricating 
the wip centers made it work doesn't mean that was the 
problem. The keys are too front heavy. If everything else is 
optimal and as friction free as possible, the action will more 
or less work anyway. It doesn't take much friction in a key 
bushing, wippen cushion or center, or whatever, to make these 
actions sluggish. Friction levels in these places in other 
better balanced actions aren't usually show stoppers, but 
these actions are right on the edge of functionality at best. 
I have, through the years, put leads on a few keys in 
Wurlitzers, when lubrication and easing didn't get it, and the 
customer wasn't interested in spending what it was likely to 
take to otherwise make it "work", but just wanted that one or 
two keys to be made to work as economically (cheaply) as 
possible.
