Remarkably easy to take each bell out of its pit and lower the assembly to the ground along with the frames and even the beams. So currently back to square one again.
With the insulation and roofing work going on around the bells work has started to remove them. Only a temporary measure but a very necessary one as the mounting beams are being lowered two inches.
Looking at insulating and lining the building around the palace ring. This may mean that the ringing installation may need to be temporarily lowered to the ground whilst the work is carried out.
