I just ordered the u-channel that I plan to use for my build. I was going to go for the large heatsinks but couldn't source them cheaply enough in Canada. Six 6' x 2" u-channels plus one 6' x 4" u-channel all precut for me by a local machine shop for $102. Will probably start it when I get back from MACNA on Tuesday. Really interesting build using this here: http://www.reefcentral.com/forums/sh....php?t=2026851

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.
