Re: DRO

Hi,

I got some cable which is pretty ideal for small DROs if not for bigger
ones. It is multistrand stainless steel core with a clear pvc? sheath and is
about 1/32 - 1/16" dia. It is used here for keeping birds from settling on
window ledges in important buildings (I used it at Sheffield Town Hall which
is an historic building). It is stretched between stainless steel pins
fixed into the stonework and projecting about 3" so that the birds don't
find anything sound to land on. When the contractors finished the job they
threw away hundreds of yards of the wire either on part used spools or in
tangled lengths where they had got it in a mess and couldn't be bothered to
sort it. I picked up an almost new 100 yard spool of the stuff 'just in case
it might come in useful' ! Seems it now will! It is very strong and also
very flexible - ideal for driving DROs and, at the price, just about right.
I would have thought the stuff used on drawing boards was a bit too stiff -
certainly when mine broke once, I was lucky it didn't take my eye out.
