Hi Andy, sorry for the confusion my mistake. To set up for photo etching would take a considerable amount of time as the original chemicals that I used at work 20 years ago are no longer available (Kodak). To use the resist from Maplins or RS would take a lot of trial and error. At present I do not have the time or the inclination to etch for profit, perhaps when I retire the conditions might change. However I still have the facilities to make masks so all is not lost.
