you're producing hydrogen gas, and in confined spaces it's explosive, and ain't to good to breathe either[
no offense taken sometimes humor does not come across on these type boards
As far as size of screw the ones you see on electrical applances, switches, plugs, those type things. Drill it on the bottom it will be hidden when you display it. Also check to see if anything is still left on the inside of the shell. Some of those held case shot someone mentioned in an earlier post. They were usually lead balls or scraps of other metal. The electrolysis will dissolve the lead.
There is something inside to the one side only. I was picking at it and it was breaking off. Appeared to be dirt/rust. Will lead make a smell/color if its burning off
It's problem just thought you might like to save them if any were in there. Did you see the Artillery site I posted in one of your other threads? It has some shells cut in half that made a nice dislpay.
5 hrs and counting......Would changing the water scrubbing and scrapping help

This meeting and presentation is very important to my digging crew.
