21st August - A great way to start the week!
A ring of fire, designed to heat the tyres on No 9 's wheelsets to about 260°c +, constructed by Alan French, was used for the first time and proved ideal for the job - of course! The expansion of the tyres allow them to be removed, with some persuasion! The wheel centres never got more than 35°c. See video section for more action. All 4 tyres were removed during Monday - a job well done!
The eccentics were removed from the driving set the previous Saturday.

Eccentrics removed for cleaning, grit blasting and protecting.
