The spire was added in the 14th-century tower in about 1362.[SUP][8][/SUP] It is both twisted and leaning, twisting 45 degrees and leaning 9 ft 6 in (2.9 m) from its true centre. The leaning characteristic was initially suspected to be the result of the absence of skilled craftsmen (the Black Death had been gone only twelve years before the spire's completion), insufficient cross bracing, and the use of unseasoned timber.[SUP][citation needed][/SUP] It is now believed that the twisting of the spire was caused by the lead that covers the spire. The lead causes this twisting phenomenon, because when the sun shines during the day the south side of the tower heats up, causing the lead there to expand at a greater rate than that of the north side of the tower, resulting in unequal expansion and contraction. This was compounded by the weight of the lead (approximately 33 tonnes) which the spire's bracing was not originally designed to bear. Also it was common practice to use unseasoned timber at the time the spire was built as when the wood was seasoned it was too hard to work with, so as unseasoned wood was used they would have made adjustments as it was seasoning in place.
Hey Bart. A friend told me years ago that an outboard motor consumes 1 gallon per 10 hp per hour. Is that right still today. I'm looking at your four motors on that boat and I just see $$$$$$. Too bad there isn't room for another.
