Dec 17, 2005 #4 Pressed Mechanical Aug 24, 2005 315 Does your press have it's leverage ratio printed or stamped into it's name-tag? If it was for example, 25:1 then for every one unit input there would be 25 units of output. _______________________________________ Feeling frisky......... http://www.tailofthedragon.com Upvote 0 Downvote
