Google damascus billets for sale. Ton of different patterns and one nine inch, forty dollar billet could make a bunch of cabs....Mel Thanks! Lots of them that I found weren't thick enough, but I picked one up on ebay pretty cheap that should work. how thick are you looking for?

rockjunquie the pattern may change some but should be all the way through they do sometimes etch it to make the pattern a little bolder just a simple acid bath sounds like notjustone may have a handle on it.

how thick are you looking for? I was thinking abt 5mm. But, I don't know for sure. Does the pattern run through the thickness of the billet or is it just on the surface? it really depends on the pattern. some do . while some others you have to forge close to shape you want then clean up or you will grind through. the pattern. using a knife for example. if you have a stack of layers and you grind a taper to the edge all that will show is lines running from one end to the other as your seeing the layers you ground through . I only ever taught pretty basic patterns like ladder raindrop sawtooth types at meetings. but I would explain it like this that bar with however many layers needs to be thought of like a topographical map. lets say raindrop for example you drill into the billet the deeper the hole the more layers you cut through exposing them. much like a lake on a topo map. deeper parts of the lake will have more circlish (is that even a word lol) lines the deeper it goes. since your drill bit is round you will end up with pretty much round circles in a perfect world but in reality after you drill the holes you have to compress the rest of the billet down to the depth of your deepest hole and distortion occurs . now lets apply that to a cab. the high dome in the center is the most untouched part of the billet so therefore your gonna have the most circleish shaped patterns. however as you grind the edges thinner your cutting through the layers so your "lakes" aren't as deep . however all is not lost cause as your cutting your still going through layers which would have been where the land was around your lake. and those make pattern too. with twists the pattern goes all the way through but gets closer the deeper you go. mosaics go all theway through and the pattern doesn't change. and you have to watch out for fakes when buying as well as unscruptulous sellers have been known to lay down a resist and etch it to look like a bar of Damascus.

ohh yeah after you grind you will have to re etch to expose the layers. if you want them nice dark lines you will want to use ferric chloride.

notjustone Thank you! We'll see how it goes. I just happen to have some ferric acid, too.
