What you're referring to as "lubricating" is just a way of describing the friction differentials between the materials. There's no oil, or lubricity, involved. </DIV> <DIV> </DIV> <DIV>Paul</DIV> <DIV> </DIV> <DIV> <DIV><STRONG>"If you want to know the truth, stop having opinions" (Chinese fortune cookie)</STRONG></DIV></DIV> <DIV> </DIV> <DIV> </DIV> <DIV>In a message dated 08/07/07 22:02:01 Central Daylight Time, deanmay@pianorebuilders.com writes:</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px;
