Hello everyone, today we’ll talk about making a knife from thin cables.
A cable knife for a beginner is not the easiest task, without proper preparation and from 5 times it may not work. When forging a cable, it tends to unwind, thereby either not boiling at all, or there will be a lot of lack of fusion. The cable is mainly made of inexpensive steel, there are alloy cable brands, and basically the cable knife has the property of rusting.
After quenching, 52 or 56 hardness units can be achieved. I believe that there is and has become much cheaper and stronger than a cable and a knife from a cable is forged for the most part for drawing. If harder steel is not welded to the edge of the blade, then the knife will begin to crumble at the edge over time. I forged a knife from a thick cable more than once, but I never managed to get a monolith. I somehow saw a method of welding a cable without flux in a pipe and decided to try and made two knives in such an easy way, this one is also the second.
And so I proceed to welding the cable.
For a knife I need
Material
- Thin cable 60cm
- 20mm to 2mm tube
- Stick rod
Tool
- Drill
- Bulgarian
- Welding
- Vise
- Horn
- Grinder
- Chlorine Iron
You can take any cables. Before welding, they need to be cleaned, the heart thread removed, if any, degreased. In general, they should be clean. The inside of the tube is also cleaned so that the cables do not solder with the tube, you can wrap the cable with a stainless steel then your cable does not weld with the pipe. Well, I weld the cable with the tube, everything is polished anyway, I just leave it a little on the butt for a change.
After cleaning the pipe, I brew one end, leaving a small gap for the removal of gases. Then I hammer everything with a cable, and I hammer a different wire into the voids, I have one simple soft and the other steel or you can just fill it with metal shavings to anyone it is convenient. After sealing the cable, I weld the handle, and I proceed to forging
I will not show the forging process itself - everything is simple there. I heat the pipe to a welding temperature so that the metal of the pipe is celebrated and forged until it cools down a little and still heat, so until we unroll to the desired thickness. When forging, the main thing is the correct uniform heating, then there will be no lack of penetration.Forging can be just from two sides, just flattened, otherwise after side impacts the pipe will play and the cable will weld poorly. That's all nothing complicated, even for a beginner it all depends on heating.
After welding, I cut off all the excess with the grinder, where the handle makes the shank. The pipe soldered to the cable is okay. After forming the shape of the blade, I grind the plane on the Grinder, about 1 mm on each side is the metal of the pipe. Next, I create a wedge on the Grinder using bulldozer. Blade length 110 mm, width 52 mm, butt thickness 2 mm. Locksmithing completed
Now I grind all 120 paper. Now I’m breeding ferric chloride, any other acid can also be baited for 20 minutes, after 10 minutes I wipe the oxide with paper. That's all, after 20 minutes the picture is visible. I wash the knife with soapy water to neutralize the acid. Then I grind it with 200 paper, just to remove the blackness and dip it for 30 seconds to shade the metal, then wash it with soap and the whole blade is ready. I proceed to the pen.
For the handle I took a piece of dry birch. He trimmed everything that was unnecessary with a knife and on the grinder gave me the shape I needed along the contour. Then he drilled a hole in a tree and planted a hilt on epoxy glue, and in the voids from the drill, having coated it with glue, he hammered wood chips. After drying, the next day I started grinding the final shape of the handle. Then he walked by hand with fine emery paper again and boiled the pen in linseed oil for 2 hours, it was also possible in wax, well, I didn’t have it at that moment. All the knife is ready.
That's all friends, there is nothing complicated, this method is easy to repeat. Using this method, you can weld a small bag, I saw how it is done live, somehow I will show you damask steel without flux. With this method, you can weld anything you want, and the balls of the bearing, and the wire in general, what you want, of course, except for stainless steel.
It took me about this knife, except for the sticking time of the handle, 5 hours - this is with tea and cigarettes. In the future, I will still weld metal using this method, but this is already in other articles. Do not judge strictly, I do not pursue beauty, I am still a beginner, I originally planned to make a knife simple from the available materials.
Thank you all for your attention and Until New Homemade Friends.
