I wonder whether a plasma cutter would provide any advantage over other cutting tools (ie. cut off wheel) in making a custom dash? Would teh cut be cleaner or more accurate? Whilst I have no experience with plasma cutters - but can imagine it would become an invaluable tool once you have one (eg. like a welder, never knew how much I needed one till I got one) - my thinking is that it wouldn't provide any real advantage, and perhaps be less accurate for an application such as this?
just a few thoughts.....
