Acctualy there is no problem Blaster4
The pattern will be explained in detail on the new book by Dr. David Darom to be publisehd next year. But I can tell you what Luciano Dorneles told me when explaining how to do it. He uses the Steve Filicietti method.
You forge the first billet with the design you want. Use that billet to form any picetures you want. Let´s say you want diamond shaped mosaic damascus.
Forge a regular billet. Cut it into 4 diferent bars. Grind them to triangular section and weld the four of them. You will get a diamond of paralel layers right?
Then draw length and cut four of those. Forge weld them side by side and up and down and you will get a square of four diamonds. Do it again and you will get a square of 16 diamonds.
Here is the trick now, draw length and slice the bar in 45 degrees cuts. The 45 degrees ramp formed by the cut will be forge welded to the next ramp, that way you get a clear and strong weld that doesn´r deform the pattern.
Now plaing with the images on it is pure creativity of how you arrange the diferent steel bars on the first basic billet you start with.
Hope this little explanation helps. If you have any question just ask and I will try to get the answers for you.
