"Dialling Guides" - Vertical Direct East & West Sundials

The purpose of the "Dialling Guides" is to provide an easy method for laying out the hour lines for a number of vertical direct east and west sundials located at any given latitude in either the Northern or Southern Hemispheres. Figure 1 is an illustration of a typical "Dialling Guide". It is designed to show local apparent or solar time.

The "Dialling Guides" are very easy to use and will help you lay out a variety of vertical direct east and west sundials. They come in two sizes if printed out at full scale. One set can be printed on 8-1/2" by 11" paper and the other on 11" by 17" paper. The scaling is in inches and will help in determining the required size of the dial plate. The "Dialling Guides" can be printed to any size but then the scaling in inches is no longer valid. This gives you the flexibility to create any size of "Dialling Guide" you need to meet your requirements. The following summarizes the vertical direct east and west sundial "Dialling Guides" available:

1. Sizes: 6 to 18 inches in 1/2 inch increments; Time Range: 1 a.m. to 11 a.m./1 p.m. to 11 p.m.; Time Increment: 10 minutes
2. Sizes: 6 to 18 inches in 1/2 inch increments; Time Range: 1 a.m. to 11 a.m./1 p.m. to 11 p.m.; Time Increment: 15 minutes
3. Sizes: 14 to 18 inches in 1/2 inch increments; Time Range: 12:30 a.m. to 11:30 a.m./12:30 p.m. to 11:30 p.m.; Time Increment: 10 min.
4. Sizes: 14 to 18 inches in 1/2 inch increments; Time Range: 12:30 a.m. to 11:30 a.m./12:30 p.m. to 11:30 p.m. 15 minutes
5. Sizes: 18 to 30 inches in 1/2 inch increments; Time Range: 1 a.m. to 11 a.m./1 p.m. to 11 p.m.; Time Increment: 5 minutes
