So I want an adapter which will allow me to attach my iPhone 5s to my Vortex spotting scope. The only adapters I can find cost $60 and that's just a few inches the other side of ridiculous. The eyepiece measures 55cm (2.16") across so I'm thinking of buying a 2" PVC cap and drilling a hole in it, gluing it to a cheap case and voila. The only problem is drilling the hole precisely in the center of the cap then removing that .16" from the inside diameter so it will slip fit over the eyepiece.
I'm thinking that once I have the hole drilled I can but a bolt through the hole from the inside, snug down a nut, chuck the end of the bolt in the drill press and use a dremel/file/whatever to shave the inside diameter. Might not be quick but it should work.
That leaves me with the issue of drilling through the exact center of the cap. How should I go about accomplishing that? Caps are cheap so I could just keep trying until I get it right but I'd rather not spend an entire day on it. Any recommendations?
