[AMRadio] perforated aluminum sheet

[Mel Farrer]

I found the best source for that at a scrap metal/recycling house.  They also have end of run stock at near scrap prices.  Most sell it by the sheet or by the pound.  I built several amplifiers and a wine storage/cooler out of it.

I did find some at Home Depo, not quite the old single hole stuff, but close 
and thin.  However, that stuff was $38 for a 30 x 30 inch sheet. $6 per sq 
ft!!!! The local hardware has 1/4 in square hardware cloth, they called it 
rabbit pen cloth. It is $0.35 per sq ft.  Not as pretty but it will keep 
your fingers out of the hot stuff, provide RFI shielding and let plenty of 
air through.  The option seems to be use nothing, that is what I typically 
do, or use the hardware cloth.  Anyone find the old stuff?  Bernie
