Thanks Dan, I like the simplicity of the application. Questions: Are the lines and numbers on a sheet or applied individually? What is their material? What makes it waterproof? Thanks again.

You can see the result in the attached photo. The vertical flat board is an alucubond panel 50x60 cm in size. The hour and date lines, numbers and text, all have been printed together and glued onto the board like stickers on a car. For the design I used Orologi Solari and Delta Cad. The gnomon is made of 1 cm thick white plastic cut to specification, the kind used for making volumetric letters in the advertising business. It's glued to the board and also secured by two small screws from the back. The gnomon is really 2 pieces: one part is a base triangle, the other is a circle and rod which is glued over the first part. The circle has a hole which lets the light through. I was not satisfied with the light spot I got at extreme hours so I trimmed down the circle plastic thickness to 5 mm using a cutter and an open flame (wish I had an electrical hot wire for this!). Unfortunately I messed up while fixing the sundial to the wall - the upper edge is a little off from the horizontal and consequently the time is also off by a few minutes. Total project cost was around 35 USD. Have a nice and sunny weekend! Dan UzaRomania --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
