Pocket Sundial

[simsmj]

This is an example of a pocket sundial, from the days when pocket watches were unknown, although some are still made today. It would fold flat, and had to be set with the user's Latitude, and the month, and also had to be oriented correctly with respect to the north, indeed some portable sundials had a small compass built in to help with this.

I based this one fairly closely on an image from the web, and of course discovered there is a very great variety of sundial designs around.

All the shapes were straightforward to make, and I had no trouble with artifacts this time, because every circle I used was reinforced with about 360 nodes before any merging and slicing! In fact I now keep several such useful shapes, including sets of 360 and 365 radial lines, for other such projects.
