Giant 20' x 3' x 2' router build

[JAZZCNC]

Charlie I've recently experimented with a 120mm PC radiator and fan with small PC pump with reservoir and it worked a treat thou I didn't cut with it for long and but did leave running at full speed for 6 hours and it hardly got warm.
I'm going to fit to my own machine and do some real world testing cutting aluminium when I get chance but don't hold your breath waiting.
If you want to try it then I'm 99% confident you won't have any troubles for what your doing and it will be very neat and travel with the spindle.
