I learnt age 12 on a heavy 19cwt 6 so had to learn to ring reasonably heavy bells. I usually rang treble to the third. We were encouraged to ring further round but it felt somewhat half-hearted. My sister and I struggled with the weight so we didn't push it. A few years after we learnt I noticed some boy learners were seriously encouraged to "have a go" on the tenor etc. They were expected to try, to fail and to get better. They did exactly that. That was just the norm.
The working group has completed it's task and submitted a report and recommendations to the Central Council for Church Bellringers. This website is minimally maintained as an archive and a benchmark to measure future progress.
