Belfry notice

 The three Rudhall bells have been tuned, and the results are beautiful!


This is the 4th. Just listen to it! Analysis of the recordings shows that all three bells are very nearly harmonically (Simpson) tuned.


Cutting metal on the outside of the sound-bow corrects the profile of the bell, meaning that true harmonic tuning becomes possible.

Here is the profile of the 5th before and after tuning.
 There are all sorts of  notes here!

 Much cleaner, and all except the tierce are spot on.

Now that all the bell work has been done and the the details are known, I have been able to update the tower notice!

In the workshop

The three Rudhall bells are now being worked on in Matthew Higby's workshop.

The first stage after removing the headstocks is to remove the old wooden pads and to cast an epoxy resin pad on top of the bell.

This is the 5th bell with the pad newly cast.

This pad is then machined to provide a flat surface for when the bell is put on the vertical boring machine for tuning.
