If you ever get the chance to use one, don't pass it up. Please excuse this, but it's like machine sex operating one. It's so spectacularly well made, and alien-seeming, that it's hard to believe. A strange ultra-precision clicking and whirring as you operate it, it's the most precision device I ever operated. It feels just amazing to operate. A friend of mine has one. $600? $1000? Depending on model. Some are really old, some 1960's. Makes my Mitotoyo mike set look like Harbor Freight. And yeah, the designer worked it all out in his head, while in a nazi death camp. He said it was the only thing that kept him going. He made some respectable amoutn from it after the war. Pretty amazing story. > and .01-mi stewart warner trip odo, precisely calibrated to the brand > and size of your tires? If I was reallllllly into it I could make an 8-digit Nixie display odo, but I'm not that dedicated :-) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
