McMaster Carr carries this kind of thing. Yellow Pages for "metal" should
turn up someone who would do it mail order.
Does it need to be solid copper, or would a piece of copperclad circuit
board work?

There are standard weathertight feedthroughs used to pass cords into boxes
that fit into a standard knockout hole. Home Depot, Lowes, and failing
that, any decent commercial electrical supply place (Graybar, etc.) carries
them. They have a rubber grommet with a tapered outside, and a nut that
clamps down on the rubber, squishing it around the cord passing through.
One manufacturer is Hubbell (which is a division of something). They're
available in a bunch of sizes, both for the outside (i.e. the hole in the
box diameter) and for the inside (the wire passing through). I've used ones
for 1/2" and 3/4" trade conduit sizes for cable as small as Cat-5. I've
seen even smaller holes.
McMaster Carr or W.W. Grainger both would carry them. If you order from
McMaster Carr, it will probably arrive a day after you order it. (I'm in the
Los Angeles area, and we used to get stuff that we ordered in late afternoon
in the early morning UPS delivery)
