Cables from Array

7th April. Just attached the cables to the roof of the workshop by first fixing an upright to one of the purlins and then a batten from that to one of the rails. The attachement to the rails is just ~ wedged under. The wood is Siberian Larch left over from the rafters and battens respectively.

The batten had a copper strip running on it's upper edge and the cables are held to the upper face by fabricated copper clamps. The clamps are made from flattened 10mm copper pipe comming out as some 50mm long and 15mm wide and 2mm thich. They are bent to shape and fastened wiyth two stainless screws. The copper strip is fastened with bronze ringed nails.

9th April. Fitted copper earthing strip to wall of workshop. Still have to connect a) the frames of the pannels together b) the panels frames to the earth conductor c) joint parts of the copper earth conductor and d) insert copper rod to earth and connect that to the joined up a,b and c.

The cables are fastened with homemade clamps
.

The copper strip has been hammered into the chamfers which hopefully will allow for any expansion of timbers.

The copper clamps are made of 10mm copper pipe squashed in a vice and then hammered hard to flatten better.

using vice to squash 10mm copper pipe.


The strip is then marked at 2″ intervals and a chisel and club hammer are used to cut into pieces.

prepair copper strip for cutting.


The edges of the pieces are then filed, shaped and pre drilled for the stainless screws used to fasten to the outer ‘logs’.
