Does anyone have any tips on stopping valve guides from rattling? I've had a new set last year, and another new set fitted a couple of weeks ago. All was fine for about one rehearsal and then the rattling is back again. I've been told I'll never get rid of the noise completely "as it's metal against metal" and there are no plastic ones available for a 20 year old baritone. Does anyone have any tips on how to cut down some of the noise? I'm feeling very self-conscious of the racket I'm making (watchit! ) when I'm rattling, (literally) my way through the lovely runs at G in VoD. :frown: The only tip I've been given so far is to place valve oil directly into the grove and see if that helps. Will try this one out in a little while. The chap who put the second lot on reckoned that he could coat them with araldite. Anyone ever heard of this being done successfully?
