fire extinguishers

done the search and didnt see anything, we cut up a rolled oil tank a couple weeks ago and wanted to take some fire extinguishers just in case. i have a friend that owns a fire saftey store that services fire extinguisers and he give me a couple to take. anyway to the point our recycling came up and to shorten the story i got three 16 foot trailers full of fire extinguishers. now these are alot of work and have to be cut in half. some are aluminum and some are steel. some have brass fittings and some have aluminum, the little cylinder in the inside is sometimes plastic, but usually steel or aluminum. anyway lots of work separating and we do it in our spare time. we have started on a pile of aluminum oxygen tanks fire fighters wear and had 50 to 60 when we started and they weigh 17 lbs apiece at 58 cents a lb. it will take us months to process this in between cars and he said we could count on at least 200 or so a month so our dead time from now on shouldnt exist. anyway we usually pay for everything but he wanted it out of the way so we settled on lunch. some of you guys out there might make a call or even a visit its our favorite score yet just because of no down time plus a steady flow of cash
