A remedy for Verdigris

[erwinspiano at aol.com]

? Well all good points. Yes it's in the wood surrounding the bushing but on extreme cases it seems to have crept into the wood. 
? Here's the deal I have two sets of 20's wippens that are absolutely free of verdigris. & third that is not. SO if the gunk is in the flange only then new flanges would solve the problem.?? Maybe they didn't get the gunk. They are well preserved? & frictions & pinning are excellent.
? As you say this would be in rare situations such as an econo job, ?not something I would usually subscribe to but I hate wasting what seems like salvageable technology when feasible.
Thanks for the feedback

It's a reasonable idea that might make sense in rare situations--though I'm
not sure what those would be--, but in general, not worth the effort and too
many potential liabilities.  At least that's my view.  If you're not
sentimental about original designs, there's certainly no reason to get
sentimental about original wippens with verdigris.

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.
