  1. I found a real anvil

    Very nice!
  2. Camping knife

    Thank you. Its rather big, but it chops like crazy. It was done from virgin steel, unlike my usual reclaimed car springs and it was really fast and easy to do.
  3. Camping knife

    Its 5160 .
  4. Camping knife

    This is what I did for my friend an ex paratrooper. Its nothing special, just the stock removal, but it sure came out nice. The handle is elm.
  5. New anvil

    Its 200 liters, close enough to 55 gallons. I hammered the sand with piece of wood somehow. I shall see how much it goes down. Should have cut the drum 2" higher, but they are easy to get.
  6. New anvil

    OK, I have put her on the sand.
  7. WIP: Langes Messer

    Now, would you consider making a try to quench such a single edged blade edge first? The Yathagan effect is well known to sabre and catana makers, but the tend to deal with it by preseting certain ammount of curvature before the quench. I have not did such very long messer like yours, but I did shorter and had no deformation - I suspect it is because the edge will become solid first, thus the back cannot overcome it so easy. Jaro

    Was this quenched edge first, or tip first ? Thanks
  9. Hydraulic press

    Its not about the size. Its the inner ones - there are actually 3 bearings on each. But the fit is too loose.
  10. Hydraulic press

    First hot tries. The guides need upgrade. But that is a small thing. Its almost too fast, too strong. On 30 mm rebar it does not slows. I need to put some flow valve on it, to be able to tame it as needed. Jaro
  11. burner spacing

    Its a good question as I am tearing down my old rockpile forge and building a new one. Assuming I have 2 T-rexes by Hybrid burners and the back of the forge is two brick slit - that can be opened and closed when doing long pieces, how far from each other should I place them? The inner dimensions are 500X125X125 mm. The burners will go into slots cut into the side bricks. Material of bricks is silimanit. Jaro
  12. 5160 interrupted quench

    5160 is actually one of most forgiving steels to quench I worked with, but why would anyone use water on that is beyond me. The preheat of oil is also not needed if you use slow oil. Many people use hydraulic, but that is opposite of what I have in mind. I have rape oil from tesco, that is rather thick, but its exactly what you want with fast steels.
  13. Magnesite bricks for forge

    I have rockpile forge, but the old bricks are slowly giving up. I have opportunity to get a pile of magnesite bricks, did anybody used them? Should be good for that radiant heat. Jaro
  14. When I was building my press, I bought this "baby" from this nice old chap, who had it in garrage for some years. Its basically 200 pounds of copper and cast iron. Had to drag it from car into workshop somehow. The flir shows, that I am really red when I lift heavy things Jaro
  15. Hydraulic press

    Just to get you an idea the size of motor this is powered by. Jaro
