I've just joined the Forum, this is my first post. I just bought a used 920 jet lathe. The manual for it that I've downloaded indicates that it should be leveled or the stand(which I have) should be bolted to the floor. Elsewhere I have read the lathe bed May twist if this procedure is not followed. I found no discussion of this topic when I searched hobby Machinist and see no evidence in pictures of casually placed machines. I've shimmed the machine so all four feet share the load of the lathe but I'm loathe to Bolt the machine in place--dedicated space being at a premium.
