Grinding a star will generate a boatload of heat if done too fast and the emitter may be damaged if it is overheated for a prolonged period of time.kevinm said:Hey, wait, I'm being dumb! Why remove the emitter fro a star, make a heatsink, and then reattach when I can just grind the star?
stoven said:Just heat the star with a heat gun or hair dryer until the Cree just pops off. Since the contacts are on the bottom of the Cree you will have to do some masking to keep from shorting out the emitter if when you attach it to your own heat sink.
