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.
|The ring of fire being tested. 110 small holes drilled on the tube.
|A nice even flame on the tyre.
|The first tyre is off the wheel!
|Axle up ended and 2nd tyre being heated.
|Both tyres removed.
|All 4 tyres removed.
|Nick Thompson, Roddie McRae, Alan French & Brian Thomson. Nathan Lightowler on 5th hammer!.
