In this video I'll be making an aluminum bronze knife to use around my shop. I made this knife from copper wire and pure aluminum. 90% copper mixed with 10% aluminum makes a very hard alloy called aluminum bronze. I made the knife by creating a sand casting and then cutting the shape of the knife out of it. I then cast pure copper pins and used them to attach walnut handle scales.

Yes, I agree. (To our benefit, I think he forgot to add the fancy annoying generic music effect that he usually plays over his voice.) This happens to be his Only video without the added distracting music playing over his voice. Most people just want to hear clear narration along with the natural sounds of the process (like this video). I don't understand why so many youtubers decide to play generic shite over their voice. It completely ruins it for me every time. It's become a plague on youtube. If viewers want to hear music while someone is speaking in a video, they can play any song with one click. There's no need for the video maker to force that stuff on us.

@@thewhitemustang Totally agree, all music playing in the background of videos on RU-vid instead of just listening to the natural sounds is so annoying, but when that music is those bloody inanely fast buildup beat bop lazar sounds, it's so irratating and ruins any videos that it just puts people off watching the video altogether.

Low melting points is one of the great advantages that bronze age weapons had over their early iron counterparts, which is why many people still used bronze even when they figured out iron: a bronze weapon or tool that broke for any reason could always be melted back down and recast into a totally new weapon or tool, something which was considerably more difficult when working with iron. The advantage for bronze tools nowadays, of course, is that they conduct but do not spark.

as a professional knife maker I'd say you did a hell of a job for your first knife. esp out of what nowadays would be considered non traditional materials (ironic, right?). I did, however, feel for you when you said you spent 6 hours on the bevel. I remember life before my 2x72. I'm glad those days are behind me. lol. for those that don't know, that grind would take about 3 minutes on a 2x72. but the effort and detail you put into your jig and the final result are fantastic. good job.

@jeanladoire4141

​@@terriblefezthat's beacause the only alloy that somewhat approaches bad quality tempered steel would be CuBe2 or CuCoBe alloys (copper/beryllium), wich can somewhat reach 40/45HRC. Some make non spark hammers with them. However it's a very expensive material, and its dust is toxic. Then you have copper/nickel alloys, wich can get hard but aren't as good and tough. Then you got aluminum bronze, wich can be water quenched and hardened, like steel. But it's not gonna go beyond 30HRC,and it would be brittle. He should have added some nickel and iron to the mix to improve the properties of his alloy

8:12 if you counter sunk a couple of holes in the wood before you peened the pins I think the chances of you splitting the wood would go down, not very deep ones, but just enough to allow for for the metal to bulge out, it would also make the pins to have a tighter connecting grip as there's more material hang over against the knife scales.

@_BLANK_BLANK Год назад
Countersinking is a bit too wide for the peening to fill it in, what people normally do to avoid cracking is using a reamer to slightly taper the hole.

I worked for AMSCO foundry (Specialty Steels) and we coated our cope and drag molds with a spray-on finish. Release was easier and casting surfaces were superb. We also had patterns for molding in vents and risers. Because you pull your patterns then add vents and risers by hand later, you risk distorting the mold. On your copper hammer video, you got a void because your sand binder isn't fully cured and high temps turn the binding agent into gas which has nowhere to go except into an otherwise beautiful casting. Also watch pouring temps in relation to barometric / atmospheric pressure and humidity (You need to learn how these affect laminar / turbulent flows). I know nothing about casting copper / bronze / aluminum, BUT after applying spray-on finish, we routinely aged our molds for at least 24 hours, then FIRED the insides with blow torches prior to clamping the halves together and pouring a heat of manganese steel. 'Hope this helps.

I'm a knife sharpener, about 15 years of experience. Used to really be into chasing the perfect edge. My hands can feel how gummy that alloy is by watching the video. I still grind edges by hand and talking about 6 hours to profile an edge sounds about right. Maybe not for your alloy, but for some higher end steels that come with absurdly obtuse edge profiles. I'll say this, your approach was beyond reproach! Always take your time, nothing is free. Edge packing is a persistent myth when it comes to steel blades.

Man, that blade came out beautiful, first knife or not! By the way, that 'cold forging' process he mentions is called edge packing. It's normally done hot during the process of forging a blade, and it absolutely makes a difference in the toughness of an edge, in case anyone is wondering if it's worth it.
