See my thread on gundrilling.
Gundrills are cheap on eBay. Found the size i needed the first day and bought two. I'll get a couple more real cheapos for practice.
Turns out coolant is fine for gundrilling. I need high pressure, 400 PSI min. Haven't found GPM rquirements, can't belive its more than 5 GPM. This will be the hard part to find. Anybody have something like this?
I'm thinking of trying the pump out of an old car wash. I know where a scrap one is laying around. Other ideas for a cheap skate?
