General information for purchasers of stainless steel sundials
This page gives you some general information about the ordering and delivery process (the key point of which is that we have 3 wweks or so from yuour firm order in which to agree with you the exact text of the engraving and for you to "sign it off"
The ordering and delivery process
These sundials incorporates the "line of light" which makes Spot-On Sundials very easy to set up, and very accurate thereafter. The line of light appears for about 5 minutes at every noontime - it is extensively illustrated on our website at www.spot-on-sundials.com
We have four models of stainless steel sundials, made individually for their intended location. These measure 24, 30, 42, and 55 cm. square. The angle between the gnomon (which casts the shadow) and the horizontal dialplate is precision manufactured to be the same as the latitude, and the hourlines on the dialplate are calculated for this same latitude.
They are also made individually for their intended recipient. The engraving of the mirror-polished part of the dialplate is done exactly to the requirements of the client. You may wish to have a commemorative message, a logo, a motto or poem, a brief description of the method of operation of the sundial, a table showing the Equation of Time, or anything else which will fit into the rectangle underneath the matt circle on the dialplate. (The dimensions of the circle and engraving rectangle are given on our Technical Information Sheets (links at the foot of this page). Whatever engraving you want, if you can supply it as a computer text or Word file, or as a high resolution image, we can engrave it for you on your sundial. You or your recipient will thus have a uniquely personal sundial.
