Hi Tony, I have looked around the web for more information and found a caution of:
"Because of its porosity you do not get a satisfactory anodized finish on cast aluminium which has been machined. An as-cast aluminium surface will not have a lusterous finish when anodized. (looks poor)" What might one do if they wanted to anodize the Schmoyer dial? It is aluminum cast, isn't it? Will it work on a cast surface that has been smoothed? What does it mean to be "machined"? I would think "machined" means to grind and mill the surface smooth. Have you found surfaces of aluminum (or is that aluminium - Al u MIN nee um) that have not worked well? I have found your steps very interesting. I have always wanted to find a good link of sun dialing to chemistry. Thanks Warren Thom Tony Moss wrote: > > Anodising Aluminium in the Home Workshop >
