John Cheshire rebuilt 40 feet of the spire in 1781, which was strengthened by an iron spindle running up its centre for a length of 105 feet. It was secured to the sidewalls at every ten feet by braces. In 1801, several metres from the top of the spire were replaced after they were found to have decayed. The tops of the four pinnacles surrounding the main spire were also rebuilt. By 1808, the spire had been struck by lightning three times.
