Paul,
I could have warned you if I new that you were using an OOUK corrector.
When I was salvaging one of their "Hyper-Super" 10" ODK disasters, I turned up a jig on the lathe and screwed in the corrector so that the lens housing was spinning true. Well, one of the three lenses was running out so badly that I had to reduce its diameter by 3mm in order to bring its optical centre to the optical axis. With a meniscus lens even a small wedge error will displace the optical centre a lot more than one would expect. The OOUK people don't seem to worry about such things.
and the spacers and the mounting of the lenses...
