Introduction: DIY LED Heat Sink

By overclocked2300.googlepages.com/
About: I have an associates degree in electronics engineering, But Im going to go for my Bach, and then my Masters. Currently thinking of going for a Mech. Engineering Degree too.
I made this heat sink on a Drill press with a dremel, some files and sandpaper. It is cut down from 1/2 inch diameter aluminum rod that is one inch long. The "fins" arent perfect as the dremel kept slipping when I was using a cutting wheel to cut the slots. The LED you see is Faux Mounted. My Original Idea has the Aluminum rod a bit bigger than 1/2 inch, but I dont have a lathe so you gotta work with what ya got. This LED actually doesn't produce much Heat, Its about 1W and produces around 100 Lumens (or about 78 Lumens per watt)

Im Sure Work quite well under these conditions.

Improvements/Suggestions are welcome :)
