I had a sheet of copper laying on the bench, and suffering from FFS
(first flat surface) tendancies on some occassion, it had stuff laying
on top of it. You can now see a perfect outline of everything that was
on top of it. Doubting those contacts were "gas tight", I suspect I am
ok.

But, to be "better safe than sorry" I will make it a high priority to
check and retorque all of my electrical connections.

Thanks
