When I'm machining manually, I don't mind so much using the squirt bottle for coolant supply. However, I'm not so sure that's going to cut it when I get the CNC running so I wanted to setup an easily controlled flood coolant system (but cheap - since I'm good like that). I was going to try building one using a windshield washer pump. You can basically get them next to free (if not free) at a junkyard and they're easily controlled with a dc relay off the parallel port. Has anybody tried this? Anybody know any good reasons why this may not work? The only concern I have is duty cycle, but if another pump is practically free, maybe its not an issue. THoughts?

I used a 110 V pump from Little Giant. These are normally used for condensate return
in larger air conditioners, but turn up cheap on the surplus market now and then.
