Fritz, interesting, thanks for the tip, we have the squirrel-chew problem t=
oo.
I=92d have thought that PMMA [Plexiglas (US) / Acrylic (Cdn) / Perspex (UK)=
] would be too soft and therefore just as easily chewed by squirrels as woo=
d =97 copper sheet would be needed instead, but apparently not so.   Presum=
ably they just don=92t like the taste?

I have plenty of offcuts so will try it.  Do you use the widely available 1=
/4=94 thickness, see-through clear sheet, or is black 1/4=94 equally or mor=
e effective, or does it matter, or does the thickness matter (if known)?  D=
rilling big holes in the thinner sheets is a bit of a challenge as it shatt=
ers easily.
