Google wasn't very helpful; all I got were advertisements and how-to's that say "Be certain to use the right cutting speed." We have a book with several more common metals (alum., iron, several types of steel), but I also need to know about brass, plexiglas and delryn, among others. The big Q about plexi is "What cutting fluid do I use to keep it from releasing its toxic smoke?". I'm really just looking for a nice table I can print out or download; I'd hate to buy a copy of "Machinery's Handbook" just for this one thing. :-p Mike H. _________________________________________________________________ Get rid of annoying pop-up ads with the new MSN Toolbar FREE! http://toolbar.msn.com/go/onm00200414ave/direct/01/ -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
