Here's the heat sink all welded up and drilled.

And here's the beginning on the LEDs being mount, all blues are mounted.

Should be seeing some light this week

Just a quick question...are you using any kind of nylon or other non-conductive material between the stars and the screws. I have been researching DIY fixtures for over a year and read hundreds of builds...almost all of the ones where screws went directly to the star resulted in shorts and a lot of re-work. You may have them there and I just don't see them.

Even these would work: http://www.ncix.com/products/?sku=61...tech.com%20Ltd

Yeah there are very small washers and I've tested each one for shorts.

Although I just went and retested and I did find one short so now I'm a little concerned. I think I'm going to go get some wider washers to be on the safe side. Thanks for the heads up!

Not when you include tapping that many holes.

I can't imagine any of this being easy on account of your paws!

Off to a great start there. The welding stuff is way over my head but looks impressive. You have thermal paste under those directly on the aluminum as well?
