Back view

Now that the 'Bucket' and 'Thingy-ma-jig' have been reloaded, these are now unlocked and the entire sequence can be repeated.
Time to show some of the mechanisms but, just before that, have a look at what the back of the model looks like. As you can see in the pic (although not very clearly just yet) it is somewhat complex not to say jumbled! This pic, and the next one which is a view from underneath, should be sufficient to give the more gentle Spanners nightmares.
The wiring is not helped by the fact that both 12 volt and 6 volt motors were used in the assembly.
