Oct 4, 1999 · For edge quenching I use a big, deep stainless steel steam tray. That's those things they use in a cafeteria to keep food hot. You can see it in the first shot on the work bench behind the full quench tank. I also have a third container that I …

Dec 4, 2001 · here's my quench tank, a little over 2.5" deep. If I was quenching more than 3 or 4 knives at a time I might have issues with the oil getting too hot. I've thought of mounting a burner under it, but if I have to do that I'll just stick with heating scrap in the forge.

Jun 9, 2015 · That is exactly why a quench tank should be twice as deep as the blades quenched for knives. Plunge the blade in and push up and down. No need for a longer tank, all that matters is the first one second. I just remembered another really simple quench tank agitator/circulator. The tank was about 24" high and 4-5" wide.

Aug 12, 2005 · Set up a long enough or deep enough quench tank with plenty of oil volume. Three to five gallons ( or more) is needed for a sword. The tank should be sturdily mounted or braced. A large oxygen/helium/nitrogen tank with the top cut off makes a great sword quench tank. Get the forge running at low heat so you can try and maintain the blade at 1500F.

Aug 20, 2004 · Your tank is done - Clean it out,fill it with 2 gallons of a good commercial quench oil (stop about 1" from top lip of tank.) Set thermostat to a little below midway.Plug in and let heat up until it reaches a steady temperature.Slowly increase thermostat until desired temperature is reached.130-135 is a good area.

Nov 13, 2008 · I quench knives and swords in it. One easy source for a large vertical, quench tank is cutting the top off an old 240CF oxygen/co2/helium/etc tank. The scrap yards are full of them for around $0.30 a pound. Smaller size tanks work well for regular knife quenching. As with all quench tanks, make a top that fits closely.

Apr 17, 2017 · Your example is different than a quench tank and sword. A hot blade will go right through a PVC pipe filled with oil. Then you have a burning tank with a spout of oil coming out. It happens all the time with people quenching in the plastic 5 gallon oil bucket. PVC melts between 100 and 200°F/40-100°C.

Apr 7, 2019 · Yes, you want 3 to 5 gallons to quench long blades and swords. I have a 5"X42" tank (filled about 38" deep) that holds a tad less than 3 gallons. It will heat my Parks #50 to over 100F in one sword quench. I have a military rocket shipping case in aluminum that is 48" high and about 8X12"W/L.

Jan 24, 2001 · Old pressurized water type fire extinguishers with the top chopped out makes a good deep quench tank for plunge quenching. A section of aluminum gutter ( like you find hanging on your eves) with the ends epoxied on (cut to whatever length you wish) makes a good edge quench tank. I suspend mine in a water bath which reduces the volume of oil needed.

Oct 16, 2017 · Finally getting around to finishing my PID controlled quench tank. I'm not going to be using the heating element in the picture, I'll be using a water heater heating element I'm picking up today. I just ordered a 12v electric fuel pump from amazon and a …
