  1. OK, I got a larger tank so I could quench potentially larger projects such as swords (if and when I get to that and I actually have a larger short sword in progress that will require a larger tank than what I had previously available), I typically have access to a decent amount of oil so it was more financially feasible to just use that than to buy more, I am aware of the dangerous of toxic chemicals and take precautions in the moment to deal with them (though they aren't perfect they work for what I do). And sorry for thanking you for advice, I tend to be polite to people when talking to them online, but I'll make sure not to thank you anymore. I will no longer be monitoring this post, I learned what I needed. Çiao!
  2. Fair enough. I'll invest in a good respirator. Thanks!
  3. True, but I am in a well ventilated area (outside) and keep my head back and away from the smoke. I should be fine, and it is easier and cheaper to fill a 100 lb. propane tank with motor oil than Parks 50! Thank you for your concern!
  4. JHCC, yeah it is rather curvy, but I manage to get it unbent and straight. Thomas powers, what steel would you recommend for doing a Hamon?
  5. Our school used motor oil for quenching, but it very well may be. And I have heard of many people using motor oil as a quenchant.
  6. Sounds good! I've got an old 100 lb propane tank that I've cleaned out and a few gallons of old motor oil that I was gonna fill it with for longer stuff. I'll cut the top off it tomorrow and get it set up. Thanks for the tips!
  7. Bob Brandl, oh I never thought about angle iron, I'll have to try it. I've done a few practice blades and most of them have cracked or broken, but that's more likely than not because I am quenching with water. I am in the process of getting an oil quench tank as well but I'm not quite there yet. Also, the steel is a piece of railroad tie, any good for a water quench? One of these if my description was a little vague.
  8. Steve thanks that helps a lot! Buzzkill, yeah I was thinking about the three pin method. I'll have to put something together for next time. Thanks!
  9. I have a knife I have been working on and just did a clay heat treat, but alas the blade warped and I didn't notice before it cooled down too much for me to do anything about it. I then heated it to critical temp. or just below it and left it to cool in the forge. Does anyone have any tips for softening a differentially hardened blade so that it won't crack in the next quench? A simple list of steps on annealing and normalizing to get the best result would be appreciated. PS. I used the search function on the forum but couldn't find anything specific. And I searched on Google but didn't find anything helpful either.

    I apologize. I didn't mean to start anything, debate was not my intention. I was unaware that taking discarded rail road clips was illegal, but I will keep that in mind for future. Although I have never seen anyone come along the tracks to pick up the discarded materials, I will keep that in mind. I believe I am finished with this thread. Thank you for all your help, I appreciate it. (Also, I have only been on this thread a little while and only come on when I have a question that needs answering and don't go much into other topics as my questions are usually rather specific. I was unaware of any other threads stating that this was illegal and, with all due respect, would appreciate being given the benefit of the doubt, if that is possible. And I have done research, but have heard many different things from many different sources all saying that their way works. I got the boiling water tip from someone on this forum with four circles under their name.)

    I never would have tried quenching it if I had seen cracks all over it, I checked before applying clay to make sure, but I think it may have been the breaking off of the "clay" and cooling at random points on the blade hardening in random spots that caused the structure to lose strength and crack. I could be wrong though, I'm not a metallurgist. I did also make the mistake of thinking the blade had cooled enough to cool it the rest of the way in water (a mistake I will not make again. I just didn't think it through). Frosty: It is true that it would be easier to buy known knife steel and I will do so for future, but for this knife I had steel already picked out. And now that I think about it, I remember that I didn't use the piece of round bar as was afore stated, instead I used a railroad e-clip for that blade and when I looked at the parent stock yesterday I noticed some pre-existing cracks. Maybe not enough to cause structural problems throughout the whole piece, but they were there. Thank you for the recommendation! Also, I would prefer to use steel that I didn't buy while learning how to make knives. Buying steel would be easier and better, but for now I will use the steel that is readily available to me (my cousins live directly beside the railroad tracks and can quickly find lots of loose railroad spikes and clips.)

    I think I figured out why it didn't work. The "clay" that I was using during the quench crumbled and broke off almost immediately after touching the water, it wasn't designed to cling to the metal and likely caused hardening and softening in random places where some chunks stayed on and some didn't. (BTW the blade cracked all over the place when I tried to anneal it). I am just a novice bladesmith so I'm still trying to figure everything out. Thanks for all the help!

    I'm not sure what kind of steel it is. I found it in my basement (we have lots of random materials lying around, no one knows where they come from). It's a piece of hardenable round stock the body of which was about three and a half feet long. Other than that I don't know.

    Thanks, that helps a lot. I had heard from someone that for modern steel you should use near to boiling water. I guess that was incorrect. But thanks for the tip!

    What temp. would you suggest?
