Re: Is Teflon is bad for silver?

Oops, looked closer at the invoice and $42 was material and remainder was for the 96 holes......
Ok, THAT makes more sense.
Normally purchase drops as the local folks just stock 48" x 48" sheets....
Yup. A 48 x 48 sheet from McMaster drops down to about $28 per square foot.
Teflon sheet is used to mount RCAs on the inside of the chassis...
Ah. Tried wood? I've got good results from all wood chassis using maple for the back panel. In fact I've generally had good results all around using more organic materials. At least where practical. Wood doesn't make for very good heatsinks. :)
Point is PTFE is expensive....
No, it's not cheap compared to other plastics. What's expensive are those damned holes. You're paying $42 per sheet for the Teflon, but over $150 to remove the excess and turn it into Swiss cheese. That's over $1.60 a pop for them damned holes. :)
