Your sundial needs to be mounted on a firm plinth or pedestal in an open area, with the arrowhead facing roughly north; at noon the sun is due south so stand with your back to the sun and point the arrow away from you. The top of the plinth should be as near horizontal as possible. The dial is best fixed to the plinth with an epoxy glue or something like No Nails, alternatively can use screws and raw plugs (not supplied) but don't fix these until you have aligned the dial as explained below. You may need to drill holes in the lip of the base plate, being brass and a soft metal this can be drilled relatively easily. Wait until your wristwatch is about to show an hour preferably midday. Turn the dial until the shadow from the arrow shaft (known as the gnomon) cuts that hour on the dial plate. In the summer this will be 1 hour ahead of "real" time but as the dial is only likely to be used in the summer the difference should be acceptable. NOTE: Because of British Summer Time our clocks show the time 1 hour later the time shown by the sun. I have set the sundial up in my garden to show British Summer time as I don't venture out in to the garden much in the winter. You can now fix the sundial to the plinth. You can use an epoxy glue like Grip Fix or No Nails. Alternatively you can drill the sundial base and then set raw plugs in to the plinth top. I would advise over drilling the hole and filling this with araldite. Once the dial has been fixed and the araldite hardened file down the screw heads to prevent these being unscrewed. Full instructions are supplied with each of our sundials. |
