Dear All,
Attached below is an inquiry from a colleague, Richard Kremer. Please copy him
on your replies. Photos of the wall sundial in question can be found here:
I have been photo-etching sundials following Tony's video for several years
and have written up detailed instructions based on my own experience,
including availability of tools and materials.
For anybody who wants to have a go at this here is a link to that paper:
You can find Tony's BSS photo-etching video on YouTube -

The same video was posted in two parts back in 2010:
