I have a set of vertical quench tanks, made from 4 inch diameter PVC pipe and a matching end cap. Then, as the line cuts the lower black line (Ms) the metal starts to transform from the Austenitic (soft_ phase to the Martensitic (hard phase).

I built mine from a piece of 5"x5" square tube with .1875" wall thickness. Note time is on a logarithmic scale as all the action happens very quickly at the start and then slows down dramatically. I have quenched 6mm thick 1070 steel, which probably ranks as about the lowest hardenability of steels commonly used for blades, quite successfully in a fast oil. This does not mean that you cannot quench from your forge fire when magnetism is lost but you’ll be less likely to be at the optimum temperature than if you are using a controlled temperature furnace. Plumb silly. Pattern welded steels may require some variation (it’s NOT a matter of calculating average carbon content – that’s just wrong).

Feb 26, 2017 - In this video, swordsmith Walter Sorrells shows how to make a small quench tank for water-hardening knife blades. One particularly caught my eye because it was, apparently, made for some kind of rocket or missiles. Actually, it's interesting now that Google has bathymetry (sp?)

The "limiter plate" is nothing more than a 1/4" thick piece of aluminum plate, choked full of 3/8" holes, with 1/4-20 threaded holes on each corner. were significant researchers who contributed to the interpretation regarding sea floor spreading and mirror image records of same. I have drawn a typical cooling curve representative on an oil quench in blue and an air quench in red. Judge David Baker shows host Wil Willis how to properly use the quench in this web exclusive. Judge David Baker shows host Wil Willis how to properly use the quench in this web exclusive. Thomas, my being a (retired) geologist by profession as well, here is an interesting sidelight to the magnetometer discovery.

Cool tank, nice work. I have about 3.5 gallons of Parks 50 in it. It is easier to heat/maintain to the desired temperature than a really big container. You'll be able to tell when the aurora show up directly overhead.... East and west poles flip as well for the Salmon????

I like it because i can seal it up when not in use and it is relatively spill proof.

I'm surprised Prof Dill hadn't towed you how array your sensors. Smaller size tanks work well for regular knife quenching. Your quench tank should be deep enough to lower the blade in vertically (my quench tank is a piece of 150mm dia pipe about 800mm deep). If you’re familiar with TTT or CCC diagrams this is known “getting past the knee” of the cooling curve.   Your link has been automatically embedded. I use a 40mm ammo can. We were just learning how to listen for them in WWII weren't we. You can post now and register later. I like a horizontal tank because it gives me the options of either an edge quench using my "limiter plate" or a full quench. Your quench tank should be deep enough to lower the blade in vertically (my quench tank is a piece of 150mm dia pipe about 800mm deep). Therefore, if we were to try to straighten a warped blade before it gets to, say, 2500C it will still be soft, can be straightened, will stay straight, and will not move again as it hardens.

Each hold has 1/4-20 carriage bolts threaded in, with the heads facing down so I can adjust the depth of the plate in the oil.....and therefore adjust the depth of an edge quench.
