Where can I get a sheet of heatsink?

[Judaeus Apella]

I want to cut one my self for some custum heat sinking. Where can I get somethng like this? Nothing fancy, just a simple sheet of heatsink, nothing small though. Around 5x7" or more is fine. Im pretty sure I've seen this kind of thing.... but it was a while back and I don't remember where I saw it. I can remember it though... it looked aluminum. Any type of heatsink material is fine though. Perhaps you guys know of a replacement part I can order, or even a common peice of equiptment I can find in a junk yard I can pull one off of? I'd apreciate anything you guys can give me! Thanks!

find your local supplier of metal bars and sheets, they usually have this stuff as well or can tell you where to get it

LOL, I have no idea who that would be.

Funny thing... the first thing I thought of is the ACME company from the old Road Runner shorts.

You're basically after finned aluminium I guess, you'll want to find a local metal dealer (google may help) and buy it. Most heatsinks in equipment are extruded to fit the device.

try your local audio store - they can usually order you high density extruded heatsinks in virtually any size - usually used for custom high-powered amps and the like.
