Long time since last update. I got the machine running just before christmas, It's still far from "finished" thought! I have worked on the project for about 35hours since the last update!
Here is a video of the assembled machine running!
The ballscrews had too tight fittings for the bearings so I had to sand them a little using this kind of jig:
The X-axis ballscrew has a huge nut.
The machine is now assembled and I have cut some parts with it.
The old machine's base works well as a work table.
