ill definately try the etch and color method.
i was considring another method, if i got a strip of steel about 1 meter long 3cm wide and 2mm thick and anodised then cut the strip into about 5 pieces. I would the stack em into a billet draw it out to the intial dimension and repeat.
will i be able to forge weld them (they have an aluminium coat from the anodizing so i'm not sure?
will they keep the color?
just wanna know the chances of that working before i try it out
