Just to pass the time (and to prove that I’m still here), I’ve delved back into my memory to bring you another snapshot in time from the half-cab era. This one involves the shady corner of a bus garage where a mechanic was ‘treading carefully’.
There was a time when bus operators were permitted to re-tread the tyres on their vehicles when they became worn down to the minimum legal tread depth. Maybe they still can – does anyone know?
Sometime in the 1960s (I was a small boy then) my Grandfather fixed it for me to have a look around the inside of the Wilts & Dorset bus garage in Salisbury. My eyes were out on stalks as we wandered round, watching MWs, KSWs and Lodekkas in various states of disassembly. I was even allowed to go into a pit, over which a bus was parked. I had no idea what I was looking at but I felt strangely privileged to be looking at the underside of a bus.
We were shown into a dark corner by the back doors where a couple of mechanics stood surrounded by wheels. Strewn around under their feet were zig-zag strips of rubber, the waste product of a handy tool one of them was wielding. As I watched, he held the tool in his gloved hand and guided it slowly along the shallow remants of the tyre’s tread. The tool, plugged into a substantial power supply, had a V-shaped cutting blade which evidently was heated by the electricity. Beneath the mechanic’s hand there appeared a brand new groove as a new zig-zag strip of rubber fell to the floor.
