A remedy for Verdigris

[Greg Newell]

Dale,

                I’m currently doing this job for a client on an “M”. I just
took it in today. My question regarding your idea is “how much will the
epoxy increase the size of the birdseye?”  Isn’t there a limitation between
the ears of the flange?

Hey all
 I know ...I know there is no remedy for verdigris .... except a new parts
transplant... but the other day my 83 year old Dad & I were looking a
perfectly useable set of vintage Steinway wippens except for the mild case
of creeping green crud so, We were lamenting having to toss a beautiful set
of original Steinway wippens in the trash. We started brainstorming how we
could solve this given the contamination is in the wood.  Now I know many of
us have re-pinned & re- bushed ...put on new flanges etc. & in the end all
for nothing as it returns, But with a good set of wippens approaching 1000
bucks the idea has my attention.
  I told my Dad I was thinking about how to cut out the birds eye & then
machine a new insert with birds eye & all. My thought was that if the new
insert was put in with epoxy that this would act as a verdigris barrier from
entering back into the new wood. Then My Pops says "why not just coat the
existing birds eye with epoxy & slide a coated pin thru the hole to seal up
the exposed inner wood which should prove de a barrier to any further
contamination". Then pin on new flanges. I thought the idea had merit.
  I mean for a few short hours of pinning & coating an original set of
beautifully made & machined  maple wippens could be preserved & re-used at
any level of performance required. 
  How bout some discussion.
  Dale
