Hi there! Basically my quest is as in title.
I want to built two separate machines:
CNC No.1 Bigger one dedicated mostly for WOOD, PLASTICS/ABS, and occasionally METALS routing/engraving. Parts like custom shaped/sized casing elements for electronics projects.
CNC No.2 Compact/desktop one mostly for METALS like brass/aluminium and other suitable synthetic materials like ABS. For machining relatively simple small custom parts like gears and so.

I'll need them for my own hobbyist purposes, so no need for hi-end industrial standards nor high speed and efficiency.

As for CNC No.1 I'm aiming somewhere at ~50x70cm to ~100x100 working area and moving gantry type.
As for CNC No.2 I think ~25x35cm (maybe less) will be enough, and I'd choose moving table for max precision/rigidity of gantry.

Are these sizes and construction types reasonable for my goals?

First technical advice I'll need is spindle choice for each of them.
- For No.1 "woodworker" I wanted to use KRESS 1050 as It's very available in my area, is in my budged range and seems to have good price/quality ratio. Is it good choice or overpower? Will it give this machine some versatility for occasional use of harder materials?
only drawback I see, it doesn't have electronic RPM adjustment (or does it?)
- No idea what to choose for small No.2 "metalworker"?

Keep in mind that working speed is not important factor.

Thanks for all replies!
