Sorry a little late replay,
I used a technical plastic called Delrin, 15 mm
thick. It had nothing to do with psubs ofcourse. i didn't measure the angle but
it was clearly visible that it wasn't a square cut.

Hello,
There is a small problem with aqua jet
cutting. It is difficult to explain for me as a Dutchman in
English but a water jet (even with abrasive additives) tends to act as a
bullit. At the entrance it cuts a small hole, at the other end there is
a "big" gab. Cutting thin materials is no problem but as soon as it gets
thicker the jet makes a connical hole. When you cut a round viewport
you will end up with a slightly connical one. This requires
machining afterwards to meet the neccessary tolerances.
