Hollow forms


I sent this once before but didn’t see it posted so I am trying

To solve the problem of pickle getting inside the hollow forms
after soldering, I was taught to submerge soldered hollow
objects that have smadll pinholes in clean water until they sink
or stop blowing bubbles or both. Theoretically the interior space
fills with the water so, when you put the piece in the pickle,
none of the acid gets in the interior. If desired, any trace
amounts can be neutralized by boiling in baking soda. Linda M
