THK HRW27 for Lathe

[nolage]

Hey Cnczone,
Long time lurker, and as a med student haven't had the time to really get much done beside helping a few machinist friends with the odds and ends. I own an X2 mill and some decent cutting wears and have used it from time to time to cut face-mounting evaporators for refrigeration systems using a rotary table, chuck, and slitting saw setup.

I've wanted to pickup a lathe for a while, as I once had a giant Southbend 13 that ended up having to disperse back to the ebays before I could restore it.

So after some minor discussions, and based on needing to cut Cu, Al, and some delrin/acetal from time to time, a friend suggested why not just give a shot at a lathe.

So I waited.

I hopped on ebay today and ran across some THK HRW27's, 2 rails, 4 blocks for a great price. Obviously they are short rails length wise, but just thinking about what size rails (width/etc) I might need to handle the radial loads does anyone have any idea?

I'd imagine these should be big enough? No?
