A local friend with big strong lathe straightened out my inner column (the one with the worm wheel at bottom).
Put column on lathe and centred up each end then ran the tool holder with DTI along its length to see where any off centre bends were. With those points marked he ran the holder along and wound the holder against the high spots and pushed them back to just beyond centre so when released they became central.
I did say it was a big enough lathe so no stress to it!
