Most of the ringers have commented at some time or other about the odd feel of the 4, especially when pulling off.
Some of this was due to its cracked stay, which has now been replaced. However, it still felt a bit odd.
A careful inspection of the 4’s rope and wheel revealed that two of the carriage bolts fastening the wheel to the headstock had loosened. They were retightened; the 4 seems to feel normal now.
