Continued . . .

I am hoping that the binding of the wire maketh it as strong as the rod is on its copper holder. If that has to be replaced then I suppose a thin plastic tube would hold it straight.

There are movement sensor lights around, one of which switchen on it assumed automatically as I approach my kitchen window. It is good to have these, however their outgoing radiation presents people like me with a security issue as it can theoritically penetrate the zone. So I am going to do the wall as well, and also part of the window. That will drop down and bind in the same way.
