Jeff,
I built the tank back in 1975 and used it off and on for many years. Back in 2000 I was down sizing due to an upcoming move and got rid of it with a lot of other stuff. I could find no photos but I did draw up a sketch a while back. Go to the files section of the forum and look under Craigs-files. I used this etcher with annonium persulfate becasue I had an easy supply of the stuff. The company I worked for had a captive PCB shop and used the AP as part of the process. I had an imersion heater to get it up to the 140F etching temp. Fresh hot etchant would do a board is 30 to 60 seconds.
Don' know if I would use it with Feric Chloride becasue of the mess that the stuff makes, stains everyting it touches. CuCL2 should work fine as well but out side because of the HCL fumes. AP is so clean to work with.
There are photos of my spin coater and pcb drill in the photo section under Craigs photos
