A disaster because the SRBP will suck up water and the whole board will be pretty much messed up, become conductive or something?
As for the cut itself, water jet would probably make the best cut, i'd loose just about 0.5mm of the material at the cut. Not much use, if it spoils the whole material though

. On the other hand - how do they water-cut cardboard and paper then?
Ok, i will make my way to the hardware store and take a sheet with me - maybe i can find something appropriate.
BrianH recommended me a circular saw with a blade for plastics, small teeth, etc., but any circular blade will take quite a bit of the material away - 3-4mm - and i can't do this because of the one shared edge.
THe worst thing is that i have very little space to experiment on.
I will try to think of a safe method to do this by hand - making some kind of good "guides" for the cut. Maybe doing deep scalpel cuts from top and bottom before sawing, so the outer layer doesn't chip that badly.
So, laser or water jet is a big no-no?
