Rebuild 2: House Of Flying Spanners

I've divided this up into stages as it was getting quite long and it gives me more space for awful puns:

1. If you have a problem... if no one else can help... and if you can find them... maybe you can hire... The House Of Flying Spanners
2. Grinding and grinding and grinding…
3. Some Engines - taking one apart, putting one back together
4. Some Assembly Required - actually putting some bits together
5. Winch me up!
6. The Middle Bit
7. Tub B or Not Tub B
8. What Happens Next Will Shock You!
9. Transfer Of Power
10. Are We Nearly There Yet?
11. Tanks For All The Fish
12. A Deadline Looms
13. Back To The Lab Again! - and off to Russia!
14. The Aftermath
