And there must be an unbroken connection from the bonding point to the
earthing block. There must be no joined bits of cable or junction boxes. You
can use the same cable for bonding several locations, but mustn't cut the
cable, just strip off enough insulation in the middle to be held by the
terminal.

Random thought.
Would welding be acceptable as a method of joining?
