So I broke out my caldo torch today and used it on a 6'' seized pin. After getting thru the pin I found myself with no water except for the 2.5 gal in my refillable water extinguisher (which was nowhere near enough). I got thinking that I need a portable water pump that I can fit the hoses in each side of the 1/4" holes and recover the water. Do any of you old timers have something already made up/thought of that I could mock? It can run off of 120v from the welder or 12v battery.
