50 x 50 x 20mm Heat sink

[Merlin66]

To complete a solar camera cooling project I need a 50mm Sq. heat sink.
I did order one from eBay but it seems to have gone walkabout.....
If anyone has one available from their box of bits, let me know.
Thanks.

Hi Ken,

I have a big collection of CPU heatsinks and among them there are a couple that measure to 55x60x20.
I can machine one down to 50x50x20 but how do I get it to you?
