We were set to wind big solenoids here, but then the local electrical shop (it does big electric motors), backed out.

I couldn't find a source, so I rewound three of ours after they got
dropped over a period of years. It's not difficult to do, just
tedious, if you can make a suitable form. I reused the copper wire
because it is quite expensive.
