New build with recycled parts on a ridiculous budget 120cm*60cm work area

[Greeny]

Although i have a lot of experience using big cnc machines, I don't really have the building experience to offer good advice,
but as long as you bear that in mind here's what i would be looking into if i was thinking about a machine that size.

A ballscrew for the 4ft axis , either a 2010 or 2020. Nema 23 3nm.
The 8ft axis probably 2510 or 2520 fixed ballscrew with 2x rotating ballnuts and 2x nema23.
I would personally only consider R&P if budget can't stretch to rotating ballnuts as they are pricey.

Here's a few relevant threads you might like to peruse.

Hopefully someone with more building experience will chip in.
