Video clip of sample etching on brass flanges. Part is not held in place but sits loosely, grounded via the stainless steel baseplate. Flange surface is cast, not machined, so some extra pressure could be used for a sharper finish, however no great difficulty was encountered in etching this sample.
Stencil used is a permanent stencil, mounted in a plastic cover, held manually and aligned "by eye".
Etching system used: MiniEtch EU80
Electrolyte used: #502
