These parts were made using the electro-forming process described in the post below. The Radiola lamp hood was somewhat easier to make than the Neutrowound tube-shield, but still required an hour or so to cut off the flashing and attach the clips.
OK, the chemistry experiment is done - at least for the moment.
UPDATE: I have added "brightener" (Mira-lax) to the bath. We'll have to see if the formation of nodules is reduced which will reduce finishing time.
