Hi Ed, if your early kit is felt bushing, then you are likely to encounter many of the issues that I detailed in my earlier posts in reply to you, and Nick Gravagne's comments will still apply as well.

I have an early WNG kit, and the springs are steel colored. Damn strong to begin with, too! Ed Foote RPT http://www.piano-tuners.org/edfoote/index.html Ed, Renner springs are pure beryllium copper. Are these WNG springs by chance plated to look like beryllium copper on the outside but something harder like steel on the inside? -------------- next part -------------- An HTML attachment was scrubbed...
