Hey Doug. Thanks for the report. Good thoughts all.
You might look at www.McMaster.com and search for ball screws. Or attempt to put the link below back together. Their 5/8 screws are about $1.25 an inch and the nuts run $25. I used a single nut to test lash and got between 0.001 and 0.003. I know folk who used two nuts on a single shaft and a Belleville Disc Spring or two between. I don't use the bearing end blocks rather I make up my own using trailer wheel bearings.

I am using threaded rod but it makes for a very slow machine. If anyone here has a line on good inexpensive ballscrews please let me know.
