John,
If the gnomon is outside and the dial face is inside, with a pane of glass in between, isn't there a refraction problem?

I'd tend to go with some means of mounting it to the frame. Small screw holes could later be filled and painted over." The gnomon would be on the outside of the window and the plastic film on the inside, so drilling a hole is unnecessary if you use adhesive for the gnomon. ----- Original Message ----- From: "Dave Bell" <[EMAIL PROTECTED]> To: "John Carmichael" <[EMAIL PROTECTED]> Cc: "Sundial List" <[email protected]>; "Glass List" <[EMAIL PROTECTED]> Sent: Monday, August 11, 2003 1:11 PM Subject: Re: Poor Man's SGS > On Mon, 11 Aug 2003, John Carmichael wrote: > > > You know the tinted thin plastic (Mylar?) film that people use on > > their home and car windows to cut down on light transmission?
