Mirror-drum, or Nipkow disk?

Nipow disk. I built my first one while at school using plans in Hobby
Electronics using my sister's 'The Partridge Family Album' LP, I thought
that it was the best use that it could be put to; she disagreed.

One of my later ones used a 'conveyer belt' instead of a disk which
produces a square screen.

LED or nitro-benzine as the polariser?

Polariser?
I used a neon as my light source, I didn't have any polarisation.
My later ones use LEDs at light sources and produce a much better
quality of image.
