    John.. are you doing this to all of the action centers or just the hammer flanges ? I have encountered verdigris all over on some Steinways and would think the problem is lurking in all of the action centers. A Steinway grand had new hammers, shanks and ...

    It would be better to repin all of the jacks and ream/burnish the bushings. The jacks should have little friction/low gram gauge reading 1-2 grams and be the loosest of the action centers. While you are at it the friction of the rep lever should be checked ...

    Do you all think this would work for some sluggish grand jacks on an old Estey grand?  Someone rebuilt the piano a 16 years ago, but they neglected the action.  I have tried several applications of CLP and the jacks will move freely for a month and then ...

    So...the verdigris is "gone"...as in disappeared? Or is it simply "deactivated" but visible, but causing no problems?  This is all highly interesting.  Peter Grey Piano Doctor ------------------------------ Peter Grey Stratham NH (603) 686-2395 pianodoctor57@gmail.com ...

    I do the applications first and let the action dry overnight. Once you apply the solutions the action seizes right up due to all the water. The swelling may actually help the process by sizing the center pin bushings when the action dries. Then I apply ...

    Greetiings everyone.  I use a three step process that starts with distilled vinegar (an acid) mixed 1:1 with 70% rubbing alcohol (wetting agent), apply it to the centers and let that soak in for a 1/2 hour then follow with a wash of baking powder and ...

    Jon, Patrick, Geoff and Susan Thank you for all that. I learned a few things. I do wish that plug-in hybrids were the opposite of what they are now. That is, I wish they had a substantial electric range like 150-200 miles with a small gas-powered ...

    I recommend a Plug-in Hybrid. The distance per full charge is less than a full EV, 42-50 miles on my Rav 4 Prime. But then gas/hybrid takes over when the charge is minimal. Then in hybrid mode it is gas and self-charging electric. Currently hybrid mpg ...

    It seems that because there is water in Fantastik there naturally would be swelling of the felt and sluggishness until the water evaporates.  Just like adding a solution of alcohol and water.  Once the bushing felt has shrunk, of course the flange is ...

    I have suggested the use of ammonia before, but I don't have any cases of verdigris to test it on.  Fantastic has an ammonia-like chemical with a pH of 12 (similar to ammonia), so it should react with the copper acetate (verdigris) and fatty acids in ...
