St. Johns:
That's odd, I was always told PIPS stood for Polyvalent Intake Protection System.
I'd love some advice on the construction... I'm pretty handy when it comes to things like woodwork, (built a room around an aquarium and a nice bar in my basement), but I have to admit that when we get onto small things my eyes let me down nowadays. I make the model with the aid of a big freestanding magnifying glass..
My vision is fine past about a yard but closer in I'm utterly buggered even with reading glasses... I probably should get them checked professionally.
