Thanks for that link too, I have seen this and was thinking very similar, I was hoping though as you'll see from the dimensions I've given, mine doesn't need to be as robust for cutting just wood ... or am I wrong?

Yes your wrong.!!
Don't under estimate wood because while it's softer than aluminium you have to cut it faster and often much deeper which requires strength/power.
Also don't just think strength but also think in terms of vibrations because resonance really does affect the machine in many ways, performance, quality of finish, tool wear and component wear.

Also just bare in mind CNC tends to open up other avenues and if machine is weak to start with then limits these avenues.!!
