Re: [PSUBS-MAILIST] Aqua Jet Cutting My 2" Acrylic Viewport

[Jon Wallace <jonw@psubs.org>]

Nice.  I'm not sure about stresses set up by water jetting, but I'd 
guess they are no worse than what a lathe would impart on the same 
material.  The only issue I see is the taper which could affect 
performance since the port would not sit true against the window seat.  
But I'm assuming a 90 degree cut can be achieved if the water jet is set 
up to cut that way.
