Easy-to-make wooden sundials : instructions and plans for five projects, with suggestions for designing your own pocket sundial

Excellent manual for the beginner explains how to make five different sundials. Includes templates pre-calculated for latitude. Few tools are needed to make dial more accurate locally than standard time. Gnomonics is to the scientific what the Art of Dyalling is to antiquaries: both refer to the art, science, and craft of sundials. The sundial, the oldest mechanical clock, is also the truest when properly set and corrected it is more accurate at its longitude than modern "standard" time clocks. For beneath and behind the shadows on the dial operate principles of celestial mechanics, geography, trigonometry, and magnetism. But can a sundial be built with this knowledge? Yes, in fact, with proper guidance, a good deal of sundial science can be learned in the making. Here is the guide. The book gently leads beginning diallists into sundial lore and construction. Novice craftsmen who can wield a saw, wood-burning pen, matte knife, sandpaper, and a few other simple tools can make five different kinds of sundials; plans are flexible and allow for embellishment, alteration, and variety of materials. Pre-calculated templates can be removed from the book and transferred by carbon paper to wood. Illustrated step-by-step instructions show how to build these sundials: Horizontal; Direct South Vertical; Folding Equatorial; Bowstring Equatorial; and Diptych. Ultimately, one can design a working pocket sundial! Tables are included for four different latitudes (25, 32, 40, 45), applicable throughout the United States and much of North America. A table of more than one hundred cities gives latitude, longitude, time, zone, magnetic variation, and the necessary time adjustments. A special section is given to dial correction; the equation of time, longitude, magnetic variation, hour angles. A bibliography and a list of sundial mottoes complete this comprehensive beginning manual. sundials_01......Page 0 sundials_02......Page 2 sundials_03......Page 3 sundials_04......Page 4 sundials_05......Page 5 sundials_06......Page 6 sundials_07......Page 7 sundials_08......Page 8 sundials_09......Page 9 sundials_10......Page 10 sundials_11......Page 11 sundials_12......Page 12 sundials_13......Page 13 sundials_14......Page 14 sundials_15......Page 15 sundials_16......Page 16 sundials_17......Page 17 sundials_18......Page 18 sundials_19......Page 19 sundials_20......Page 20 sundials_21......Page 21 sundials_22......Page 22 sundials_23......Page 23 sundials_24......Page 24 sundials_25......Page 25 sundials_26......Page 26 sundials_27......Page 27 sundials_28......Page 28 sundials_29......Page 29 sundials_30......Page 30 sundials_31......Page 31 sundials_32......Page 32 sundials_33......Page 33 sundials_34......Page 34 sundials_35......Page 35 sundials_36......Page 36 sundials_37......Page 37 sundials_38......Page 38 sundials_39......Page 39 sundials_40......Page 40 sundials_41......Page 41 sundials_42......Page 42 sundials_43......Page 43 sundials_44......Page 44 sundials_45......Page 45 sundials_46......Page 46 sundials_47......Page 47 sundials_48......Page 48 sundials_49......Page 49 sundials_01 1 sundials_02 2 sundials_03 3 sundials_04 4 sundials_05 5 sundials_06 6 sundials_07 7 sundials_08 8 sundials_09 9 sundials_10 10 sundials_11 11 sundials_12 12 sundials_13 13 sundials_14 14 sundials_15 15 sundials_16 16 sundials_17 17 sundials_18 18 sundials_19 19 sundials_20 20 sundials_21 21 sundials_22 22 sundials_23 23 sundials_24 24 sundials_25 25 sundials_26 26 sundials_27 27 sundials_28 28 sundials_29 29 sundials_30 30 sundials_31 31 sundials_32 32 sundials_33 33 sundials_34 34 sundials_35 35 sundials_36 36 sundials_37 37 sundials_38 38 sundials_39 39 sundials_40 40 sundials_41 41 sundials_42 42 sundials_43 43 sundials_44 44 sundials_45 45 sundials_46 46 sundials_47 47 sundials_48 48 sundials_49 49 Presents plans and instructions for constructing five different wooden sundials, and includes pre-calculated templates, as well as tables for four different latitudes
