    I have just ordered a VFD and water cooled spindle, Now to save cost and more important clutter I was thinking of just putting a large water tank under the table instead of a radiator and fan for cooling. How large a tank will I need? will 20 litres be large enough and how many litres a hour will the water pump have to pump to keep the spindle cool if worked hard like cutting aluminium? and if I ran antifreeze as coolant what percentage of antifreeze to water will I use?
