How thick will the chinking be? Is the cable clamped to the logs? If you want to be able to replace or plan ahead, could you place a 1" pvc pipe over the cable? This pipe would be actually a half pipe, just the outer half keeping the chinking off the cable. Clamps would have to be removed. A secnd full pipe could be placed a log higher or lower for future wire possibilities. Just some thoghts. Jon
