Get yourself a milling machine ! I just aquired a nice Bridgeport last summer, the machining handbook gives you the formula for drilling holes around a circle, once you have tthe diameter and the number of holes you want it's real easy, some of the digital readouts have it in their program.

James,
It looks like you could of used a rotary table on your drill press like this one I'm planning on acquiring, to make the drilling of your viewports a lot easier.

I'm also considering aquiring this XY Cross table for my drill press, until I can upgrade to a large Mill/Drill.
