I recently bought a polarizing condenser for my Orthoplan, but the
polarizing filter won't rotate. I applied some xylol into the gap where it
should rotate but the only effect was that the paint of the markings
disappeared :-(
I loosened the lock screw of the filter, and also a very tiny screw on the
side of the filter, I removed a sort of prisma-like filter from the bottom
of the condenser, but it won't rotate.
My plans are to (try to) remove the (foil) polarizing filter and then soak
the whole thing for a night in xylol or something (isopropyl alcohol?).
Or has anyone a better idea?

Theo,
I would wrap the unit in Kim-wipes or something similar and use a
solvent that won't kill you. I object to using stuff that will kill
me, I kind of like me and I've found death to be boring. Then I would
very gently soak the unit in a good solvent, heptane or alcohol, for
about two hours, making sure the unit stayed wet.
If it came apart, fine, if not I would take it to an expert.
Does this polarizer looks like a Polaroid or is it a polarizing cube?
Thanks,
Kevin Cunningham
