Regulating a 63' Teflon action L for a good friend, I was surprised to find verdigris at the hammer flange centers. This is a solid Teflon action with nice firm centers and no clicks, however with verdigris, hammer-flange friction in some cases exceeds 10 grams. Steinway warns against lubing Teflon parts, nonetheless I have to wonder if there is some Q & D means of easing the verdigris without damaging the teflon? I know that whether we properly disassemble, clean, ream and re-pin the parts, or simply squirt in a bit of miracle juice, the verdigris will come back. However, something that will extend the use of these otherwise moderately worn parts, is entirely appropriate for this particular piano. Given the recent discussion of lubing key-bushings, I'm just concerned that the solvent/carrier in CLP for instance may dissolve/harden the Teflon, while perhaps ProLube may not? Anyone know for sure? Thanks, Mark Cramer, RPT Brandon University -------------- next part -------------- An HTML attachment was scrubbed...
