Lab style heatsinks

[lamborgini8]

I never thought it would be so hard to find a empty lab style heatsink that I can put a laser in and use in a scanner.

I have had all the suggestions about buying a cheap module from DX or ebay amd riping out the cheap diode but then I have the PSU, driver and damaged diode laying around with no use... Plus from what I have seen the ones on DX have no mounting holes.

I have thought about making my own and just drilling out a hole in a rectangular block of aluminium but even that isn't easy as I can't find anywhere that has a decent sized block and I have no way to cut through metal that thick.

My only other option is to ask a local metal working place but from my quotes in the past asking them about a laser enclosure I will be looking at around £70 - £100 which is rediculous.

Any suggestions or anyone selling any? It must be a relitivaly small heatsink thats the rectangular block shape.

Pat (laserman532) also makes some nice ones. I think i got the last of them, but i think he's going to make some more. Ask him and see.

I've used Pentium4 heatsinks before when size wasn't an issue.
Here's one I picked up recently, which will be promptly drilled and tapped, (so the diode can be directly inserted) as soon as I'm next back home and have access to my lathe.
(see attached)

They can be had off ebay for a few quid, (go for the highest GHz rating ones when the Prescott ones were all the rage, as they usually have a copper base due to the high heat transfer needed.)
