Hi Joe, One question I do have which was asked before here; http://www.cnczone.com/forums/showpo...6&postcount=54 but I don't believe it was answered. Do you need 3 or 6 Dumpster clamps as it appears as though you are using them at both ends of the the ACME thread in this photo http://www.cnczone.com/forums/showpo...5&postcount=64 Thanks, Claudio
