Epoxy granite
https://www.youtube.com/watch?v=Px07lIp01GY Mill track for linear guide out of large square steel pipe. haven't noticed any deformation. The tube is now stuffed with epoxy granite 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. Guides are raised 10cm above base, creating a depression for chip deposits. See http://www.lathes.co.uk/scinta/index.html scinta model on lathes.co.uk.

Mill
https://www.youtube.com/watch?v=5CzpytZd4_A Mill the groves out of support platform out of solid slab aluminum, DIY build. Large millford type mill build. Two x six centimeter metal plate welded onto large pipe. Fill pipe with concrete or epoxy concrete for vibration damping. Thirty kg of epoxy concrete is $120. modelengineercouk Thought this may be of interest to other members who might have a Myford VMB milling machine and how I converted it to CNC. The machine has developed over time. Here is its current state of play...The Blue bits are mostly the added items.

Stepperhead
http://www.lathes.co.uk/stepperhead/ Designed and built by Alan Jackson, the Stepperhead is an attempt to combine, in one unit, the range of facilities found in a medium sized lathe and a small vertical/horizontal milling machine. In the 1950s David Urwick had designed and built the ingenious and versatile Metalmaster http://www.lathes.co.uk/metalmaster/, a device that combined a lathe and milling machine without unduly compromising the attributes of either.

Hand drill rotates at high speed with a cutting tool, lathe part is done at angle to cut worm pattern out of plastic. The angle of the drill bit determines how thick or thin the worm gear edges are.
