    The control plate will act as a shield, as it's conductive. In theory, it will be grounded by the signal ground, i.e. the output jack ground is connected to the volume pot, which in turn is connected to the control plate through the pot's chassis. Having said that, I would run a strip of the copper tape over the lip of the control cavity so that it's in contact with the control plate. That might also be how you get continuity between the output jack ground and the rest of the shielding, if it isn't otherwise connected, though you're probably better off soldering a ground wire from the shielding to the volume pot chassis to ensure a good connection.

    I have slid on a piece of heat shrink over the tip connector of the output jack. I have the contact side open....and the other side covered just in case it touches the inside of the hole. The jack socket will be a recessed tele style that will be square to the edge of the body at that point. I think the socket may stick across the hole a little.

    I fully intend to solder a wire from one of the pots to the bottom of the control cavity. I think everything will then be connected from bridge through strings to pickups to pots to the cavities.

    I use a nylon washer on the pots to shorten the amount of the pot shaft that protrudes and enable the metal knob a better fit. I don't know if anything actually touches the control cavity from the pots.....I suppose a multi meter will tell the tale.

    I will not bother with tape on the under side of the cavity cover....but I did intend to put a little tape lip on the cavity to touch the control cover.

    Thanks for the info.
