That looks a bit like my X-2 hack (although mine isn't a
real X-2, it is the same machine.)
See http://pico-systems.com/minimill.html for some photos.
I found one big problem was the Y axis handle assembly did
not have a ball bearing, but just a bronze sleeve and the
handle jam nuts would slowly tighten up until the axis bound
up. The X has a pair of ball bearings with the handle nuts
preloading them. So, I cut the Y axis handle bracket to
work the same way.
You can just barely see it in one of the pictures.
I used to use this machine for demos at shows, but there
haven't been too many shows lately.
I also put a spindle encoder on it first, as it was a lot
easier to do than on a Bridgeport.
