Finally got all the LEDS glued to the 72" heat sink. I alternate blue and royal blue.
here are the close ups:

Good luck!
Testing and tinning are two different things. Usually you would test each LED to make sure it's not damaged before gluing it to the heat sink. You can do that with a AA battery tester.
Additionally, you'd usually pre tin the solder pads on the LEDs so that in case you made a mistake and shorted/broke an LED you wouldn't have to pry it off the heatsink to put on a replacement. I recommend pre-tinning all your wires and solder pads.

Confused by Lucas comment about tinning. If an Led broke, you'd still have to pry LED "star" off the your main heatsink.
Tinning would just make it easier to remove the soldering wires so you can put on a replacement LED, right?
Or am I missing something about tinning the back of the "star" heatsink before you epoxy it onto your "main" heatsink?
