  1. Thank you. I made a vertical tank but have been hesitant to use it until I had better understanding of this. I knocked over my horizontal quench tank. It took four hours to properly clean up. It gave me new motivation to do the further research for the vertical tank.
  2. For quenching, there is the Leidenfrost effect where a vapor gap occurs and the cooling rate is relatively low until the temperature drops enough for wetting. Upon wetting the cooling rate increases significantly. With metal thickness on a bevel, and this effect, I have seen natural hamon occur in a horizontal quench. In a vertical quench the Leidenfrost effect causes the wetting transition to progress up the knife or sword, so in my mind this means the higher up the piece the slower the overall quench rate and therefore an influence on the hardness from tip to end. Convection in the quenchan
  3. Your comments are much appreciated.
  4. The Ridgid brand hardened up very well. If I find out the exact alloy I will use it often.
  5. I decided to try my hand at a pipe wrench knife over the weekend. I know a lot of these have been made, but it I enjoyed the process. I’m thinking of making one or two more. Maybe a dagger. What do you all think?
  6. Sleek. It makes me want to use it just looking at it.
  7. Using your own knives for a short while may help your design work. It is important to know what works, instead of what just looks good to your eye.
  8. If I may chime in... Learn everything you possibly can about metallurgy. Alloying elements, what temperatures and other contributing factors affect the structure of the steel, TTT, etc. Find out what books are used in bachelor's degrees, and later masters degrees in metallurgy, and read them. There is more to knife making than almost any other career (or hobby), if you take the time to learn it correctly. Practicing the art is only part of it. You will never regret knowing the technical aspects. From steel you make from the ground yourself, to the latest high alloy particle steel, learn i
  9. Thank you Alan. Dustin, I found this rusted and beat up at a swap meet for $8. I shaped and hollow ground it, put it through the heat treat and temper cycles, hit it with a wire wheel, followed by a sisal wheel with black rouge. I was careful not to blur the lines. The tip line looks blurred, but it is just the photo.
  10. I only have one dog. She's not aware she's a dog and doesn't spend nights outside so I don't have to worry about her. They roam my area in packs of 8 to 10. A couple of the pics from that night have three in the frame.
  11. Taken Christmas night 2016 outside of my back fence. Infra-red game camera at night. Healthy coyotes in my area.
  12. Hollow ground with a temper line not yet developed.
  13. I finally got around to finishing this. Not the best pic, but its the only one I have of it. Ebony, nickel silver, pomele sapele.
  14. I'll have to try the denatured method. Just last week I tried the stainless foil, but I tried it with an induction heater. The foil acted as an electromagnetic shield with the induction. It was a complete failure, though I am sure it would work well with a traditional forge.
  15. It looks like you got your temperatures perfect. Excellent work.
  16. Thank you Jan. Here is the edge of the billet in process.
  17. I disolved as much borax into a glass of water that it would take and had some left over in the bottom. I soaked the water in between the three layers and then caked a little wet borax on the edges. I used two layers of 1018 with a thin core of 1095, and forge welded it by hand. It welded very easily and there were no inclusions. I know others use this method, but this is the first time I have tried applying the borax wet beforehand. It worked well for me.
  18. I finished it with cold blue and cotton cord, which I sealed.
  19. I had an old buggy spring laying around for years. It didn't spark like 5160, and wasnt as active of a spark as 1095. My best guess is 1060. Whatever it is, it hardened up well. It took a couple of hours of hammering. I trued up the tip with a file and started the curl with a large pair of plyers. The rest is hammer work. I've shown it to a few people and the response has been 50/50 like/don't like, mostly because of the curl at the butt of the knife. Let me know what you think. Thanks.
  20. Shoulders take some months to come back after getting cut on, but they do come back. Great pictures. The fourth from the top really catches my eye.
  21. I was given a couple of old rasps that had been out in the weather for a long time. The middle blade was ground from the other half of the top rasp. The bottom blade was forged from a smaller rasp.
