Harry said "Hay, before you put away the plating equipment why don't you try to make a Radiola 18 hood?" Well - - because I don't need one. But, the challenge was there, so I did.
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.

Above I think that the new one is on the left.
Tabs installed on the back.
Some of these were, or have become, darker so the one above was painted to match.
While removing the nodules created on the outer surface of the form, I noticed how attractive they could be. So I salted this one (below) while the surface was still active, that is, fresh from the copper sulfate bath.
The colors on the copper nodules are easier to see in the off-focus shot below.

There was no need to do this step, but I thought it was cool.
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.
