I've been doing a bit research for a potential new machine build, and an epoxy granite base is looking like the preferred constructions method.

However, I've not found much information about the various options for mounting linear rails.
I've come across builds that use complete internal frames surrounded by EG, ones with mounting surfaces held in position with a basic internal skeleton, ones that use steel rails cast in, ones with just inserts cast in, and ones with inserts epoxied in after casting.

Is there any reputable information covering the options, or is it just a case of picking what you think will work best for your own individual requirements?
