> Willie,you would be right on both counts then. Those are MUCH nicer,as well as totally different. The pic you showed kind of reminds me of that Thomson glide-rod shafting,which is 58-63 Rockwell,C scale. I have a small chunk of it,guess I'll have to try sanding it,LOL. I read something in a metalworking forum somewhere about a new high-tech alloy called Maxamet,which has been consistently testing at 70-72 for about a year,awfully close to low-range carbides which start at about 75,and just might be cheaper,if you can find some. I wonder if some of the high-tech ceramics would be any good. Tommy D.
