Tommy, Two things I see wrong with your solution: #1 welding rod is softer and will indent more rapidly than steel. #2 grinding the tops with a belt sander will create too much heat, which will cause loose bridge pins! Even with hand filing, there is considerable amount of heat created and should be done alittle at a time, allowing to cool sufficiently. After all the whole idea of replacing bridge pins is to give the strings a FIRM seat at termination. <G> Best Regards, Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
