    Cheers, I built that little Jig to make twisting all these bars on my own a bit easier, seems to work well. The furnace I also built this year. Its lined in Fireblanket it may be called rock wool? in the states. Its rated to 1600 degrees C. The inside of my furnace is lined in about 3 inches of it and a skim of wet fire cement to stop it all falling apart and hold the heat a bit more. I have been ripping bits of what was left of the roll to use as doors.

    Cheers Alex, getting there first one coming together, chose to do the Nakiri first as its the easiest one to work out all the forged lengths/slice size etc for each piece in the composite.

    Plus I wanted to go through the whole process with one blade, before laying out all the materials and welding the others.
    Pieces laid out 3 bars of twists, basket weave bar and the san mai of high layer laminates on the edge.



    Lots of welding









    Then cleaned up in acid before touching the faces....



    A little more forging down then into the ladder dies



    Will see what that looks like tomorrow

    So here is where we are are after heat treat and a quick grind back. Showing 63hrc on the edge material, as the spine has 01 in the twists for contrast these parts are also very hard, so I flame tempered the spine back to around 55 hrc with the edge clamped between two plates..





    But I can spot an issue with the san mai and the deep ladder dies. I got the percentage of core and cladding correct, but the dies are just too extreme for this is san mai and in this case where the material will be hollow ground on the faces I can tell we will loose the cladding and just have the high layer core exposed. looks pretty wonky as is, should still look good after grinding, but the plan for the rest is to make the cladding into a much higher layer and use this as a single laminate on the edge so we can get the most of the tight ladder pattern on the edge. So by mistake or evolution there will be a difference from the design here. But on a plus the deep ladder dies really work well with the composites and we will have a tight ladder on the edge.
