I think Bruce just posted abou this guy's work: http://somender-singh.com/component/option,com_frontpage/Itemid,1/ Someone posted about it a few months back, and I looked at it then... It sure looks like snake oil, but there's a lot of people who claim to be using it with excellent results, and the described physics is NOT insane. But I can't find a single photo! I'm not clear from the descriptions just what this grooving looks like, how critical dimensions are, or anything of a practical nature. I can understand if it's subtle and complicated, but there's got to be SOME rule of thumb here.... Anyone got photos of grooved iron similar to ours? _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
