Thank you Sir, well there is probably a saying about pushing the boundaries making mistakes and learning to get closer to perfection.
Ed's Suji from the accidental billet.
I heat treated it, cryo to max hardness. There are large differences in hardness between my uber carbon mix and the mix with veins of pure nickel, (Which should be on the spine half only) The super damascus is 66hrc everywhere, the nickel veined parts test uniformly at 56 hrc. I'm surprised tiny veins of pure nickel make that much difference but it does as tested. I will finish this blade to keep with me as an example.
So I have enough of the stuff that works for 3 of 6 orders. it looks great on the blade too but i'll keep you in suspense about that. This stuff will not be wasted, I will mke a composite of it with and edge steel to use for wide blades like special grind nakiri, will look stunning in that format. I will make some more of the feather damascus as planned next week for the other orders. So bit of a set back, but it does all translate to more material and more great knives ultimately.
I got a couple of stainless damascus clad pieces welded up at the end of today also, and a proper test of my new burner. Its the beans
Held upper stainless welding temps to within a few degrees with much less fettling than my previous set up.
Equally accurate control at 800 degrees or so for heat cycling, turned down so much here its just pushing out a visibly slow rolling curtain of flame, bearly running and holding 800 degrees to within 10 degrees or so.
Someone clever worked this one out a long time ago and its put together with off the shelf parts, I'm sure you can get something similar out there, here tis
