Don't know whether this is of interest to others, but I'd have a go if I had the room.

oh wow! i've never seen a CNC mill made from concrete! that's pretty wicked. but, one caveat. i think getting the necessary holes for everything would be a total bitch to keep on tolerance since it's concrete. sure, it's a great idea and i'm sure that's got some good stability and resistance to temperature change, but man, getting the necessary layouts would be so time consuming. but, if you've got the time and desire, i'd go for it.

thank you for the link though.

The secret of getting a useable lathe or mill with that process is that you have to make all the stationary metal parts first and jig them accurately in place before you add the concrete ! It works great if you start with the "Gingery" lathe/mill plans and modify the plans for the use of the concrete !
