I need some help and suggestions for my CNC upgrade. I an replacing my router with a water cooler spindle. I live in upstate NY where it's below freezing most of the winter. My shop is unheated. How do I protect my water cooling system from freezing? Do I drain the system everyday after using it? Blow it out with an air compressor to make sure all the water's out? Can I add anti freeze to the water ? Will the anti freeze hurt the spindle? I can't be the only one working in an unheated shop.
Thanks in advance for you assistance.
