Not bad, but a fiver down the car boot should get you a computer power supply which will deliver at least that. Just put a resistor on the +5V rail (google it) to keep it on and stable.

Wood does with a good size cutter, but that's not the reason as I hardly ever cut wood an no DIY router is rigid enough to use that much power. Why use plywood when you can use 3/4" aluminium
It's for my friend from school who I will be helping (well, letting him use my router - he doesn't need help) build a smaller rigid machine to be used mainly for cutting aluminium and occasionally steel (hopefully)...knowing him probably titanium too. Anyway, the reason for that much power and the whole coil switching thing is to be able to get lots of torque at low rpm, which is useful for drilling/facing among other things. I don't expect to use anywhere near the full rated power of the motors.

Top speed 1500, mm/min? Is that rapid speed or top speed you use when cutting?
