By an oddity some of the early polar flip data came from searching for enemy subs off the west coast of the USA. Personally, I quench everything horizontal, but when I built my quench tank, I built it with horizontal quenching in mind. After spending the past year practising knife making, it always surprised me how many people take their quench tanks for granted. Recognised quench mediums are:-. But when the South pole is right up there all the Australians have generations of jokes about "falling off" and "standing on your heads" they have been saving up just waiting for the polar flip. The whole lash up is to prevent punctures and contain a boil over. So now it’s at the correct hardening temperature and next comes the quench. Stainless steels are much more sensitive to incorrect hardening temperature than carbon steels. If the poles flip I just hope the salmon will get confused and come down to Florida. were significant researchers who contributed to the interpretation regarding sea floor spreading and mirror image records of same. If you mass produce blades then cooling of your quench tank may be a necessity. medium? Terry has been telling me about hanging out with you and Jim Clow. Horizontal & Vertical Quench Tank I had this idea a while back while on coffee break and sketched a quench tank that would accommodate both horizontal and vertical quenching.

It may not display this or other websites correctly. The curve on the diagram that appears between 7000C and 6000C is the knee. I achieve this by removing the blade from the oil at about 4000C (oil auto ignites at about 4500C) so as long as they don’t flash but are smoking heavily when I remove them from the oil I’m at about the right temp. freezer? The tank does not have a mesh basket yet, but I was thinking about it. They read it like a bar code from orbit now. As with all quench tanks… Even then our subs were enough quieter we could creep around a lot more. Pretty amazing stuff.
