Usually if that doesn't work I replace them. As for sandblasting, doesn't sand get embedded into the felt? I suppose if I run into a 'candidate' for experimenting I will try it. What air pressure settings, etc? Thanks, Greg </BLOCKQUOTE> Greg,  I blow the action out after blasting. Around 50 - 60 pounds is usually a good pressure. Hazen Bannister</HTML>
