Winding would not be that hard. One easy way might be winding each
spiral layer between two solid disks and feeding some varnish with
the wire. Once dry it would be a solid pancace. Still, quite a lot of
work.
Nasty stuff at least with smaller wires. ;)

Such coils are used even today in some high-voltage transformers. One
example might be pole-pigs which have to be able to take huge overvoltage
becouse of lightning strikes. Such devices are quite often wound as spiral
"disks" and many of those are stacked on same coil form. Proper connection
will allow parasitic capasitances to get large to distribute voltage
gradients
better.
