Karon-
Since you are dead set against attaching the gnomon to the exterior glass pane of your double pane window, I only see a couple of alternatives: 1. Inside Mounting- This is your plan of support strut(s) attached to the window frame that hold the gnomon in place above the glass. I'm not a big fan of gnomon support struts unless they are absolutely necessary because they cast ugly confusing shadows on the sundial. Using this option, your sundial would be mounted or hung inside the house next to the interior glass pane. I'd put thin rubber or foam spacers between the dial and the glass pane to avoid contact with the interior glass pane. If you change the design so that it only requires a point-in-space nodus, you would not need any support struts. You could simply attach a single rod to the exterior window frame or the building wall next to the top of the window. This rod could be attached anywhere that's convenient and its angle isn't important and doesn't need to be aligned with the polar axis because only the shadow of the rod's tip is used to tell time. It has a additional advantage in that it can also be used to tell the date if you want date lines. I like this option a lot. I have a photo of a dial like this somewhere on the SGS website, but I can't find it. 2. Outside Mounting- You could hang your sundial outside of the window (again using thin rubber spacers to avoid contact with the exterior glass pane). With the dial mounted outside, you could attach the gnomon directly to the glass or the metal came without using support struts.

If I did attach to the window, it might cause the vacuum to break. Even if it didn't, it could void the warranty. I had considered doing a real stained glass piece and hang it inside the window but that is just more space to leave open before the style appears. That was why I was thinking a floating style. I planned to use a Polar Axis (triangle) style. Basically, it would be the same thing as one attached to the surface but with the bottom chopped off. Imagine you took the triangle and drilled a couple of holes in it 2 inches up, ran poles through them, then cut off the part below the poles. That is what I am thinking of doing. That leaves the tip of the style in the same point in space, it just leaves an open space between the bottom of the triangle and the window. I will probably extend the tip of the style beyond the end of the triangle, just so it is easier to read in summer, but, it will still be, basically, a polar style.

Will your stained glass sundial design require a polar axis style (a triangular sheet or angled rod) or a point-in-space style (also called a nodus)? What can't you attach the style to the window glass? There are several ways to do this. Here are two webpages that may help you: http://advanceassociates.com/Sundials/Stained_Glass/TechInfo.html http://www.sundialsoc.org.uk/Bulletin/Bulletin-23ii-Carmichael.pdf John Carmichael From: [email protected] [mailto:[email protected]] On Behalf Of karon Sent: Tuesday, August 02, 2011 3:54 PM To: [email protected] Subject: mock stained glass sundial Ok, so I have the insulated windows but I want a stained glass sundial. So, I plan to paint a sundial on the window frame using glass paint. The only problem is, I cannot actually mount the style to the window. So, I want to back check with you guys. what I am thinking about doing is, paint the dial as planned. Then, I'll make a paper style and use that to check my distance. I can mount two bars across the window 2-3 inches away from the window. I can attach the actual style to the bars. So, I can use the paper style to adjust the amount of material I need to leave off the bottom of the style to have the correct shadow. In effect, I am creating a floating style. What do you guys think. I wanted to check with folks who have done real stained glass and see if you think the floating style will work.
