By ripping up a microwave oven, bolting a horn on the magnetron and blasting the dirt, and looking at what got hot with thermal imaging, I can see the metal. Dirt has some transparency to ir. Can someone tell me where to get polyvinylidene fluoride (PVDF)? Thanks in advance. Larry

Am I missing something, or is this the type of equipment that would need more tooling and precision than something you could do in an average kitchen?

Thats pretty much where I am planning on doing it. If you're interested, I'll tell you how to do silk screens, etching, etc. Larry

The article says it is cheap. Digging thru The google stuff, I came up with a minimum of $200 for a small chunk. I would like something a little cheaper. Thanks for your input. Larry

Scroll down to the bottom of the page.

And don't worry about it being an industrial supplier, McMaster will sell to anybody who has cash or a card. ;-)

Cheers! Rich
