What vacuum John? I find the Henry does not like fine dust. I know it
only take a minute to bang the filter clean. Am I expecting too much of
the vacuum?

Anything with a filter or bag will hate plaster dust - new gypsum
plaster being worse than old lime stuff.

I usually use either a pre-filter cyclone on a ordinary shop vac (a
henry would be ok here), but even that clogs in time due to the finest
stuff getting through my (none to sophisticated cyclone):

For a quick job I use my Dyson. In the case of my old DC01 it is better
with the HEPA filter removed - some dust will get through but not much.
My DC14 however will capture pretty well anything without noticeable
filter clogging.

If doing it day in and day out then perhaps one of the cyclone
collectors as used by chimney sweeps would work quite well.
