[quote author=64longstep I don’t have a power hammer yet the work will be done with a 22 ton air over hydraulic press and by hand. I’ll be starting with a stack and see what kind of pattern pops out… [/quote]
Forge a bit on the thick side, and you can make patterns interesting by either grinding and forging out, or by fullering or punching and grinding. Punching with a star drill ought to leave you with star patterns after you grind... Or forge, twist, and reforge to shape will also give an interesting pattern. H.H. Ellison Davis documents Viking "damascus" blades made of separate square stock twisted and then forge welded together. I have the book somewhere...
I think if you have the forge welding down, you have an opportunity to play.
