PAPER CUTOUT SHADOWS all you need is scisors (see also popup dials)
CUTTING SHADOWS is a PDF file that has a number of simple sundials that you can cut out and have function immediately.
Polar, Armillary (and summer time equatorial), east and west transparent meridian, and a horizontal dial are included, as well as useful EOT (equation of time) and longitude and latitude data. Also has a 3d popup unfolding horizontal dial and a popup dual dial having both a vertical and a horizontal dial plate!
This file is helpful when reading Illustrating Shadows because it allows a dial to be rapidly made and then manipulated to see how orientation affects the shadows.
These are a very very few of the dials discussed in ILLUSTRATING TIMES SHADOW
You may consider downloading SIMPLE SHADOWS which talks only of horizontal sundials, in a do-it-first-then-fix-it-next step by step process, as well as discussing what happens and why it works and then stepping you through the process. Tables are provided as well as theory. SIMPLE SHADOWS is selected from ILLUSTRATING SHADOWS, it is in essence a free sample of the main book..
