RE: Photo-etching

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: https://dl.dropboxusercontent.c

You can find Tony's BSS photo-etching video on YouTube - www.youtube.com/watch?v=HkpCCA-hgrc The same video was posted in two parts back in 2010: Part 1 - www.youtube.com/watch?v=ML37yRmAsOA Part 2 - www.youtube.com/watch?v=PAW0q6i7aqg > On Aug 31, 2016, at 12:34 AM, Wojtek Galinski wrote: >
