Hi Simon, the problem was that shell made a bad result, the inner shell surface is kind of mangled.
Instead of shell you'll get a better result in this case making a profile curve like this and then revolving it:
That's what I did with the attached 3DM file which should now boolean ok.
I am planning on overhauling Shell to use the ACIS library which should make it a lot more reliable.
