Hey John My first name is Dale. Yes I can. When filing any hammer you will reach a point in the filing over the top/strike point & the felt will cause the sandpaper paddle to resonate/squeak. This always indicates living breathing solid fire breathing pay dirt felt has been struck & the tone comes up and dances. Richard Davenport demostrated this for me 27 years ago. I'll Never forget it. Dale Can you explain what you mean by "when the felt begins to squeak"? Thanks. John -------------- next part -------------- An HTML attachment was scrubbed...
