I'm hoping that someone here has, or can direct me to, a SIMPLE design program, method, etc of calculating hour vector line for a horizontal sundial. My understanding that the line are not equal, but are different angles as the day changes.
Anybody have any solution and or suggestions? Ideally, a program where I can enter the latitude and it will calculate the angles based on that for each hour. I can get the rest - angle and location of the center gnome (center piece) but am completely stumped on the hour line layout. I would like it to be pretty accurate as well if possible.
I have done a lot of searching, and an only find sites that use formulas that I can hardly read, let alone understand!
Appreciate any and all help!

My Latitude = 52.26N
