I went down to the local fire extinguisher store (Clarey's Safety) and they had hundreds of old, steel and aluminum metal tanks from defective fire extinguishers laying around waiting to be recycled. I asked if I could buy one and they GAVE me two! Just took it over to my bandsaw (they were all discharged) and cut the top off. I now have a very durable quench tank that will hold about two gallons. I had to clean out some residue powder from the tank, first, but a garden hose did that nicely. Great for quenching long blades point down (fillets) .
