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?
