A remedy for Verdigris

[Barbara Richmond]

RE: A remedy for VerdigrisI think he means that the center pin would pull the epoxy through the hole--then the hole is left to dry before continuing with bushing and pinning.  Something like the Damaged Bird's Eye Repair contributed by Ed Sutton listed in the Tips, Tools and Techniques column in this month's Journal (page 9), but using thin epoxy to coat the hole (and not trying to build up the bird's eye).

I could be mistaken, though.  :-)

  Interesting. Won't the pin become a rather permanent feature of the whippen? Or, by coated, do you mean with Vasolene or something else the epoxy won't grab onto?

  Maybe epoxy isn't the only answer: Aren't there a variety of wood sealers and waterproofing agents that might penetrate and seal the pores and veins in that wood?

    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.
