When I use 1/4" stock I start with a five piece billet. After one fold I have ten layers. When I use thinner stock I start with a much higher count billet maybe ten layers. After one fold I will have twenty layers. A higher count beginning billet will put you ahead of a lower count billet.
This is the billet after the power hammer flattens it.
Following Ed's advice, I put the billet in my paragon with large pieces of steel and heat to 1350 degrees for two hours and then let it slowly cool overnight.
Then I pretty much do stock removal with the billet.
Any questions, let me...
This is what the billet looks like after the round dies in the press. I will make a full tang knife, so I don't use the round dies the whole length of the billet.
Next I put the billet back in the forge to prepare for forging flat under the 100lb power hammer. I know in a Damascus ladder...
This is what the billet looks like after the press. The pieces for the billet are 3" long and 1" wide. This will make a billet of 9" x 1/4" x 1 1/2".
Next I go to my 100lb little giant power hammer and draw the billet out. I hit the flat and also the edge of the billet.
Then I stack them up and using my wire welder I weld all the seams shut. After welding on a handle I put it in the forge which has been running and is over 2200 degrees. I leave in the forge for maybe 10 minutes to be sure it is up to heat, then go to my press.
Ok, I start with five pieces of steel. two 1/4" pieces of 410 SS, two 1/8" of 15N20, and one 1/4" 0-1. I grind off all scale and stack, the SS on the outside, next is the 15N20, then the O-1 in the center.
About a year ago I asked for advice concerning San-mai blades. Ed Caffery took the time to write a long post with some very good advice on the making of San-mai blades. This saved me hours and hours of frustration. I was planning on fluxing a SS billet with a 0-1 core and weld it like...
Karl, thanks for the answer. I made a SanMai blade of wrought iron and 1082 and used my ladder pattern dies on it. It turned out like this.
I was thinking if the ladder dies worked on the San-Mai stainless billet it would have a good pattern.
My billet is 3/16 " 410 ss on the outside and the...
Karl, you make the most beautiful stainless San-Mai I have ever seen. Thanks for the pictures.
What shape are your drawing dies?
If I used ladder pattern dies do you think the billet would separate?
Also, after grinding off the stainless fire scale, I can see why some leave it on.
Thanks to Ed Caffrey and Bill Burke for information they gave on making stainless San-Mai.
This was my first attempt. It's a core of 1084 between two layers of 410 stainless. I thought about using my ladder die on the blank, but have heard that it's easy to separate the 1084 and the...
Aquafortis is a acid, Nitric, I think. It will stain 1095 steel. There is a very good U-tube video on using Aquafortis. Go to the U-tube site and try typing in Aquafortis and see if you don't get it.
