I got my ballscrews and nuts from reidtool.com thompson signaw I think they were called the 5/8" diameter .2" lead screws/nuts. I bought all non preloaded nuts and preloaded the Z axis because there wasnt room even after milling the bed for the X axis.
Those plans for that mill are very interesting how he has that set up, he is turning the nut on the Z axis rather than the screw, The one thing I dont like about it is it looks like it is using the stock x and y screws/nuts and it is using small steppers. you need at least 300oz/in for good performance.
