The tube is now stuffed with epoxy granite(wikipedia entry) and making an excellent lathe bed and absorb Vibration. I'd say you go for it. It's cheap as chips and works like a charm if you attach some hiwin style linear guides to it. Epoxy granite, also known as synthetic granite,[1] is a mixture of epoxy and granite commonly used as an alternative material for machine tool bases. Epoxy granite is used instead of cast iron and steel for better vibration damping, longer tool life, and lower assembly cost.) http://www.cnccookbook.com/CCMillEpoxyFill.htm (forked from http://www.cnczone.com/forums/epoxy-granite/30155-epoxy-granite-machine-bases-polymer-concrete-frame-47.html#post274123). See slant bed lathe cnczone.com When you consider that even a heavy "bench" mill like the IH still weighs just under 1,000 pounds, while a really small commercial CNC mill such as the Haas TM-1 weighs in at about 3,000 pounds, you can see we hobbyists are challenged to do whatever we can to increase machine rigidity! , Part one, bed risers lathe epoxy granite youtube ,  https://www.youtube.com/watch?v=-0Cn0WRXPKs. longest thread epoxy granite cnczone.com Haas lathe with square linear guides http://s24.photobucket.com/user/mahockett/media/haas11.jpg.html from http://bbs.homeshopmachinist.net/archive/index.php/t-21705.html.
