Project is 1/2 complete. I did the math for the Summer and Winter Solstices and laid out where I want the Meridian Line ( 166" long ) to run along solar noon on a true N/S line.
After some laser positioning, I put a large (10"x 8") hole on the upper side of my 4" thick aluminum lanai roof, glassed and waterproofed it, and put a smaller hole ( 2") underneath.............which I disguised as a SUNflower. It looks great.
Now I'm marking solar noon (using the SunCalc App), and checking to get one end of the meriridan line on the driveway perfect. June 20th should do it.
Although I can lay out the rest of the line with a laser, I think I'll wait six months to get the Winter Solstice!
The other half of the project is the design of the meridian line.......inlay a brass strip, paint it, inlay tiles, glass baubles?? And what notations to put on it. I could overlay a 1" x 1/8" brass strip which gives me the option of stamping dates into it...........or? I'm open to ideas.
It would be a chore to route out a groove to make the strip flush. I have several months think about it. No use rushing.
