George's 8x4 router-me-bob

[Jonathan]

I'm probably interested ... I am considering using this system instead of the traditional.
In my project I'm planning to use 2005 Ballscrews with Nema 23, (3.1 or 4 Nm).

If the machine is big enough to consider rotating ballnuts you do not want to use less than 10mm pitch screws.
I can make some more, however I'm currently busy making another machine and other parts so it's a matter of how soon you need them?
