On the Saturday, we had another look at the brakes, and took the master cylinder off. And, yes, a tiny vent hole was completely blocked, which caused the brakes to bind. Now truly sorted, even though it took all evening to get them satisfactorily bled!
We took the K4 to the tramway museum after church on Easter Sunday. It was a steep run, and we got there fine, except for running out of petrol (twice). We arrived just as the parade started, and it was overcast but dry. Dan, James, Tim, Michael and I tried out a turntable ladder drill (based on the 1943 book, but modified to take account of the fact that this is a very manual ladder – almost nothing is power-assisted). On the Monday, we had Dan, James, Dave M, Michael, Rob and myself, but it is amazing how long it takes to get everyone organised when it is raining.
Despite the rain, we did three demonstrations each day, and a fairly good crowd each time. We ran them as training exercises, explaining to the crowd how and why we were doing everything. I started by explaining that we had some “common sense rules to prevent accidents”, and they were, basically, “don’t drop anything on your colleagues, don’t endanger the public, and don’t let the ladder fall over”, and I commented, that in 70 years time, this would probably be called a ‘risk assessment’!
