Would love to know how you did the no negative at the bottom connection.

Ok some pics for you first the Mechanical squonker I mentioned, similar in design to a Lil' Pinch, but different in that it is more robust and used a beryllium copper leaf spring for the button and a solid silver negative battery contact that connects to the top lip of the battery ( necessitating the removal of a small section of insulation on the battery).
this means there is next to zero negative path run from battery to 510 and has no spring, with the silver floating pin taking up any slack.
