I need some info on what kind of coolant is cheap, easy to clean up and so on. I just finished putting up my tower and will try to see if things work the way I want it to. All I have to do now is run a wire to it and plug things in. Here are some pic's. The shot will drop to or in a 55 gal drum that stands 3 feet tall. That means the shot will drop 22 feet. I still have 15 feet till I touch the roof to work with if needed.
