[The Grizz]

Not as of yet, I have been very busy with work & Adams tank to get started on mine but soon I will be on the heat sinks.

On the up side the wife has agreed to let me build the tank in the dinning room so I don't have to try to move that beast of a tank up from the shop.

Well today I received a package of more LED goodies, delivered by Mr. Modular LED himself Martin.



5 - 120w drivers


1 - 75w driver


1 - 75w driver for XP-G High Noon kit ( requires a higher output amperage )



Still need to get the 2 - 38w drivers for the Red & Green LED's & also thinking of getting a 3rd on of these to give me 6 controllable channels on my controller

holy crap man......your gonna need clearance from air traffic control to fire that thing up!

[The Grizz]

So I finally got a chance today to start building the heat sinks for this tank. I have decided to do 2 - 39" x 12" heat sinks both will have 136 LEDs but will have room for more.

Got my main plates of 1/4" aluminum cut & 48 pieces of 1/8" x 1" aluminum flatbars as well.





First 5 flatbar fins tacked on:



Now 10:



15:



20:



And finally the last 3:





As you can see in the 2nd last pic I removed the very first flatbar fin, yes this was planned because I am going to wrap the whole out side of the 1/4" plate with some 1/4" x 2 1/2" flatbars.
