After getting all the parts of the mill down into the basement, re-assembly was relatively easy.

In preparation for my CNC conversion, I ordered some 1.25" Ballscrews with zero-backlash nuts. |

These are rolled ballscrews - really transmission grade, although they are 0.001"/ft lead error. They should be suitable for my purposes and they were a lot cheaper than ground! |

Putting the table back on the knee was a little tricky to get both parts in the same plane. |

Because the main casting got pretty scratched up while being moved, I sanded it down, bondo'd the gouges and repainted it with a two-stage epoxy type paint. The color match is very good. |

The knee and table weigh almost as much as the main casting. |

I came within an inch of the maximum height of the engine hoist. |

I probably should have put the head/ram assembly on before the knee - the extension on the hoist wasn't quite enough to reach so I had to push it with one hand while lowering it with the other hand. |

All back together! |

You can see the 2ton hoist from before, which I used to move the mill into position. A long crowbar and some 1/2" steel rods probably would have worked better but I didn't have any. |

Ready to go to work! |

You can't really tell from the pictures, but the mill is framed by two lollicolumns, which make it a bit cramped when you have to access the sides of the mill. |
I even fixed the DRO which I'd broken in dissassembly. The VFD which I'm using to convert single-to-three phase is also very nice to have.
