Extra tips:
Model so the faces' fronts are 'outwards' - context-menu 'reverse'...
Depending on the Style settings the front color is generally 'off-white' and the back color 'bluish' - your faces look like 'backs'...
I have reversed the face of the bell if that's what you mean TIG:
Well it's back and better than ever 
And when it cropped up in conversation yesterday my friend told me his brother has a 3D printer, so he can print it - perfect. Just need to figure out how to make the stl file converter plugin work now. 
It came to me, you just attach the .skp file... 
If anyone wants to run an eye over it for errors at the 3D printing stage I'd be much obliged
I was putting some measurements on and the 'Spinning Beachball of Death' appeared, my component has disappeared from my computer 
I have sent an error report.

Depending on the Style settings the front color is generally 'off-white' and the back color 'bluish' - your faces look like 'backs'...Model at a 'reasonable size' - geometry [edges and facets] <= ~1/1000" cannot be created [because SketchUp's tolerance thinks that the two almost coincident points forming the ends of an edgs are coincident and they don't get made so the related geometry fails to be created]: if your object is likely to make that issue, then you'll get holes with followme, intersect and similar tools - to avoid it Scale up x100, create geometry and then Scale down again - the tiny geometry can exist after the shrinking - but it cannot be created initially...
Thanks TIG, What is a "reasonable size"? My component is 80mm across, is that too small for SU?

What you show in your screen shot is that the Follow Me path makes a turn where you don't want it. It would probably be easiest if you draw the half torus slightly away from the rest of the geometry and combine them after. Make sure you are only using a circle for the Follow Me path. If you aren't doing so, preselect the path, get Follow Me and click on the face of the profile.

You know I tried that a hundred times (only a mild exaggeration ) I guessed it might be something interacting and making the Follow Me turn on a strange tanget.
Thanks Dave, whatever magic you worked from the other side of the world has solved it 
and I now have my component:
Very happy, only another 4 or 5 versions of my component to design before I go off to the shed
Hi all, I'm very new to SU and am having some problems with a component I'm try to design.
I have drawn this shape many times but recently have been having the above problem crop up. Sometimes this aberration is inside, sometimes outside. I spent 4 hours last night trying to figure this out. Sorry, I don't know how to post the .skp file
