I'm planning the cooling system for my 6040 CNC (800W water cooled spindle) and am not 100% sure on what I need.


When I look at other CNC builds, they all seem to have huge reservoir/tanks. Far larger than I am able to find on any PC parts place.


I understand that if you don't want to put a radiator and fans then of course you will need a larger amount of water. However, if I use a single radiator and single fan, is there a rule of thumb about how much liquid coolant I will need then?


Also, any tips for a place that sells larger tanks? Are people making their own out of acrylic and glue? Is that a viable option?
