You can't make decisions about moving capstans until you know how friction
is contributing to your problem.  You shouldn't make decisions about
replacing parts without an analysis of the action leverage and the weight of
the component parts.   If the action was heavy with lots of lead before and
you use the same specs to replace the parts why would you expect anything
different?  DW by itself won't tell you much, you have to check the upweight
as well.  Not sure where to start but I wouldn't look to center pin
lubricants to solve your problems generally.   Kansas City is offering some
good classes on this very subject.  Good place to start.

Mick and all. 

I asked Mick about heavy DW on a '79 Steinway B.  I just replaced all
hammers and shanks with S&S parts that weighed out the same as the old
ones...just a little heavier since the old ones had been filed a few times.
(I call this Ham-shanks when making notes) 

Before DW was over 60g in the bass, and high 50's in the treble.  Lots of
lead in the keys. Ugh! (thinking about moving the capstans) 

Just for fun, before I left for a couple hours, I McLubed the wippen action
centers.  When I came back, the samples I juiced did indeed come down about
10g!!  I'm sure it's just a short term fix, but wondered if yall have tried
this?
