Saved by a 4X2

The prologue.

She's off already. Now listen - calm yourself dear, yes you in the curlers 3rd row back.
Without that block of 4X2 to hold it up....
Titter ye not....
I would'nt have been able to slip/shove it in.

Haynes Hint: Battery corrosion can be kept to a minimum by applying a layer of petroleum jelly to the terminals after the cables have been connected.

Thank Destructus (the God of DiY) that the Knutsford Boots was still open at 17:55.
