Thank you ! Thank you ! Thank you ! I followed your advices and managed to forge my first Cu-mai (1095-Cu-15n20-1095-15n20-Cu-1095). It's a partial succes because I had difficulties to weld the outer layers of 1095. But I have a smal part I can use to do a blade. I know I didn't take the easy way, begining forging by a Cu'mai. It mas a challenge to myself.
Holie krap,wow,I am so fascinated by Cu-Mai and this just made it so much easier,just wanted to say that is not forge welding heat,copper melts at that temperature,that's why you can't put 2 layers of different steel on each other,truly amazing work and I can't wait for the final project,also wanted to ask if you can try a Cu-Mai katana,don't know how it will be done but it will look amazing,love the video
Man you are braver than I am! I am afraid being in the forge for that long that I would accidentally over heat it and melt the copper into a puddle in the forge. Thats why I welded all the way around mine before forging it. That was super cool man!
3 attempts later and I am still struggling to get a full billet. My first attempt was two layers of 15n20 with a sheet of copper inside (which worked in a small part, but most delaminated), but watching again, it looks like you are doing copper on outside and 15n20 in the middle? - I trioed that as well and only got a small section to fuse... cut the pieces up and stacked and tried again, and still one de-lam between a layer of copper and 15n20. - How thick are the pieces of copper you are using? I just flattened out some pieces of copper pipe, so maybe being that thin is making it more difficult? Either way, I am determined to get it down, but think it is going to be a lot of trial and error, so any advice is highly welcomed.
I have used baling wire on my mokume also, works well. Nice to see a less complicated process to make the billet; seems like most folks end up welding sheet metal around the billet, which doesn't seem necessary per your technique.
This was awesome to see, been improving my technique with mokume gane using quarters. and getting ready to first start with my first san mai billet and want to progress to cu mai with copper. You are not using any flux in your welding with the bailing wire?
I try it!! But i have some doubts, My forge weld seems to ve correct, but when i try froge it only de Cooper deforms and not the Steel in the, what could cause that?
@@theriversexperience9383 yo forge it or to forge weld? I weld at that temperature i think, and well then when i forge it happend that, maybe i wasnt well weld.
If you don’t mind my asking how thick of copper were you using and did you put a piece on each side of the steal? And for the final you just added a piece of 15N20 in the center correct? Just want to give this a try. Thank you in advance.

Excellent! I'm happy it was helpful.
Sitting and waiting. Hurry up man. Drilling those holes was the kicker if ya ask me. Billet on brother.
Very impressive, Sir
Thank you Jason!
Great technique and your explanation makes perfect sense. I learned a lot. Thanks!

That’s gonna be sic!!!🔥⚒💪🏻
Looking good, can't wait to see how it turns out.
Awesome video, however, its a terrible first one one on this channel for me as now I am waiting impatiently for a second!! LMAO
Glad you enjoyed it! in the mean time check out my playlists for builds you can binge watch until the next video posts.

Thanks 👍
It was definitely sketchy lol. The full knife billet is the tricky part, 13 layers of copper and 15n20 only held together by bailing wire.
Looking forward to see how it turns out and what the pattern ends up looking like, good stuff.
It will either be cool or weird lol, either way it will be a pattern.

Great work but i would be happy to know the sequence of layers of your work and material you use in this masterpiece

Looks interesting! Curious what the final outcome will look like.
sweet!
Kewl stuff guy. At the end I thought you were going to hyperventilate with excitement!
lol, I did too.
Cool series man. Can't wait to see the next part. This is gunna be amazingly easily one of your coolest builds lol sorry man had to
🤣🤣 when I said it, I was like wow lol.
Mokume Gane, Cu Mai, Tanto.....could you please list some source information to learn about these? Thanks a lot!
How hot do I need to get the forge?
I have 25 thou copper stock, will that work? Also! Could I use tool steel for the core?
This was awesome to see, been improving my technique with mokume gane using quarters. and getting ready to first start with my first san mai billet and want to progress to cu mai with copper. You are not using any flux in your welding with the bailing wire?
Nope, no flux. When doing CuMai you are basically brazing the pieces together. The copper acts as the binding agent.
And with a simple high carbón Steel Will Aldo weld easily as with the 15n20? Great vídeo!!
A lot of different steels will weld to copper. I always say try it out and see if it works.
@@theriversexperience9383 at what temperature aproximately do You set the weld?

@@matiasshanahan5164 you just need to get it up to about 1750°

Where did you get the tongs you are using?
I got them from a local bladesmith that was retiring.
Do you sell copies of the blanks on your board

The copper is 1/16" thick. This was 4 layers of copper and 3 layers of 15n20.
@@theriversexperience9383 thanks for the reply excited to try this and apparently I need to learn to spell steel smf.
