laser barrel

this should keep a 30mw greenie cool LOL

That looks like brass, but I can't really tell. :-/ What is it?

yeah brass and big LOL too big here is what i'm gonna use for my blu-ray (well try and use would be better LOL) this one is copper.

So between the three, brass is the worst heat conductor and copper is the best, with aluminum in the middle? :-/ Is there anything better than copper?(that is also worth wasting on a hearsink)

I guess you have a lathe if you plan on making a heatsink from that huge chunk, so theoretically you shouldn't have problems with the smaller copper block

Silver & Gold work better too I have the silver but i'd need to melt it into a rod LOL come to think of it maybe I will just make the head out of silver ahh nevermind I don't even think i'll be able to make the one out of copper. still have no idea what I will use as a switch.

As far as the Lathe goes I have a tiny one and am not very good at using it, but there is a big one at work and they will let me use it if I beg.

Lol, but the copper block doesn't look that big.How tiny is it really?I have a small one, well table sized.I could round that up with no problem :-/

Forget gold and silver, just make a diamond heatsink Using a huge chunk of diamond just to dissipate heat is a way better use that using it to look at how shiny it is :
