How to Make an Extremely Useful PVC Overhead Camera Mount
Save yourself some money - file into one and see for yourself. Brass, plated with silver........
solid high grade silver......not. Just Silver plated brass.
Silver is too soft to use for connectors in pure form. Sorry, but what you have is still plated brass - not solid silver, nor pure by any stretch. 33 years in military avionics, and dealt with AMP, Amphenol, Kings, and many other suppliers, but no solid silver connector - ever! Too soft....and the plating is 30 microinches or less in thickness. For a wakeup, try the Gold refining forum - other experts will open your eyes to the plating, value and safe recovery methods.
Awesome job, and congrats on the addition to the family!6mm thick sheeting, perhaps 6 MIL? 6mm is one thick vapor barrier....:)
