I was talking to David at plasma art. It is a company that does computerised plasma cutting of custom signs. I saw his bike signs for harley, Indian, etc that were all powder coated and he reckons he could do the OzStoc logo in metal. Ideal for the man cave or the back of a trailer. Can be made to any size. Reasonably priced too. He has some good pictures on his facebook page and they could be transported in a pannier easily enough.
