[Bell Historians] Trebles on higher numbers

[Martin Davies]

I understand that heavier clappers have just been installed in the 
front 4 at Canterbury to good effect..... but the extra treble 
hasn't received the same treatment. Also the 9th has been quarter 
turned

were cast to chiming weights, albeit quite heavy ones. The treble is 
just over 3 cwt, and the front end sound noticeably weak. By 
comparison, the eight at St Cuthbert's Darlington (cast by Gilletts 
in the year before the St Wilfrid's bells, same tenor weight (18 
cwt) and keynote (F)) are more satisfactory as an eight because the 
trebles are heavier and more powerful.

the treble's clapper ball is the same as that of the 10th.
