I built a Z-axis that could make prints up to 800mm (aka the Stupidly Tall-merod. Didn't need a second motor. It was fun to make some crazy tall vases but printing tall stuff is difficult as the top of the Z-axis would wobble about with the momentum of the moving parts so you'd end up going super slow and reducing your axis accelerations. I think the tallest thing I've ever printed on it (apart from the test vases) was about 350mm, so I've since scaled it back to 400mm.

I think this was the rod: [www.worldofcnc.com]
I found an M5 threaded rod on ebay, it arrived all bent up so I had to straighten it as best I could, which wasn't ideal but as long as the top of the rod is free to move about the X-arm shouldn't move horizontally (learned that the hard way, I had it captive to begin with)
This is how she looks now:
