- This is POC (prof of concept)- the test which open new possibilities in Dark Blade Knives workshop! I wanna make great stuff, things nobody tried.. Damascus patterns on mokume gane? Brass instead of copper? in this episode I'm trying to check if both of this things are possible!

Outstanding job. Looked tricky as hell. First time seeing a feather pattern.
It'is- separating to make feather pattern took almosy 1h. You have around 10sec (maybe around 60°C) gap to hammer the billet. After that the risk of delamination goes super high. Thanks a lot Cody👊! Hope you have a great day! -David
This was sort of exactly what I've been wondering for a week. I'd suggest looking into using aluminium bronze instead of brass as it's melting point is closer to copper and nickel
I agree- using bronze gives better chance to make it correct (this attempt was just an experiment). Unfortunately I couldn't find bronze sheet anywhere, so I used brass. Thanks for watching!
@@DBCraftWorld You could try making your own aluminium bronze alloy, using 90% pure copper and 10 percent pure aluminium, I'm going to try this test myself soon.
Robinson foundry on TH-cam has 2 videos making the alloy and making knives with it
@@rorrrralol I''ve made a casting foundry and I've cast a few things, so making any bronze is not a problem. Problem begins when you need to fabricate a sheet from the bar. I don't have tools for that.
Thanks a lot for "Robinson Foundry"- I've seen one of his video but I didn't checked others. I'll try to find those what you've mention.
It never occurred to me to try making mokume gane in my heat treating oven, but of course that would give precise temperature control. Thanks so much for the idea!!!!
Yes. If you make it first time I think it's better idea. there is tiny range of temperature when the Copper/brass is soft but not liquid yet and you can weld it only in this temperature. Gas forge heat up the top layer faster- in the oven the temperature is much more even.
I just started sand casing with pennies. Its amazing how different the metal becomes.
Yes, you can easily cold forge it, but in case of mokume gane with copper-nickel you can't do it without making a delam. there is such small range of temp when metals can be forged simultaneously.. the most fun fact is that experience from Damascus steel is worthless.
Thanks a lot for support Hawk! hope you have a great day, -David
Oh, an one more thing- There is very tiny moment when the brass is still not liquid but sticky- Casting is a good way to learn about how aluminum/brass/copper works with the heat! I've looked on your channel- I'll spend a while on it- you have interesting stuff out there Hawk!
Thank you! My stuff is pretty niche, you have to really be into costuming to like my videos, and I tend to ramble a bit. I am going to do more sand casing though, I've been doing to for years, and I think it's time so show it more on my channel.
That's gonna look great on a knife. I wonder the patina over time will do with the looks of it, i think that's gonna be awesome!
Great job David!
Thanks a lot Bart! This was a great and very educational experiment- very necessary to the whole series of great projects I have!
Try Silicon bronze in place of brass, 1025C as opposed to 930C. The zinc is brass is very reactive at high temps. Also there are specialist fluxes for copper alloys, used when brazing. Really interesting video, love your work.
Hey:)! I had no idea silicon Bronze exist! I mean, I knew there are different type of brass and bronze but I didn't know there is bronze that melt in
@@DBCraftWorld No problem also take a look at the properties of a high tin phosphor bronze, high melting point and harder than stainless steel.
@@landroveraddict2457 Thanks again :)- I'll take a look!
This is an awesome experiment! I've never seen it before. Which kind of coins were you using? Thanks! :)
Thanks Phil! I wasn't prepared with tools (that is for sure lol), but I've reach the main goal. Honestly I don't remember what coins they where. They have to be made at high nickel copper (most of "silver" coins made before 60's are made from this alloy). You can use "new silver" (it's the same thing). The only difference is in price.
I love brass. 😊
I'll definitely not leave it like this- this is just beginning! I want to focus on mokume gane and start to put it on most of my projects! Thanks a lot Matt for support!
Thats a tough project to undertake. I could tell that took alot out of you.
One suggestion, get a bigger chisel next time. 😄
What do you think about copper brass? Should be the same as nickle copper?
lol, that was the only chisel I had, but you got me- I should be "a little" more prepared
Copper-brass mokume gane might be easier to make. There is only 200F difference between copper and brass melting point. Nickel-Silver melts in higher temp than the copper (I didn't found exact info, but Nickel melt in 2650F, so the nickel-silver melts in temp between copper and the nickel) , so at the end I think copper-brass mokume gane should be more forgivable!
Thanks for support Adam!
Hey brother, let’s set up a donation to get you a TIG
Hey:)! This is great suggestion! Thanks a lot for that👊!
Literally like watching a 5 year old try to fiddle with tools that are ridiculously too big or small and have no idea how they work lol. A fun vid but u gotta work on those tools to fit better.
I admit, I wasn't prepared for this task but the main purpose this video was "if I can make mokume gane at all". Next time I'll definitely spend some time to make the right tools. Thanks for watching!
