I too like morphs thinking on that cone.

Only I would have went a bit different on the fins. More of a curve. but still I like the way the block will target the heat. What would be interesting. If the copper cone is a tight press fit to the aluminum hoising. Is take a very small heatload. centered under the copper slug. And take tem readings on the copper core and the aluminum as close to the core as possable. Take the temps at small intervals and see if the copper heats up faster then the aluminum, or see if the aluminum draws the heat quickly from the copper. im still not sold on the copper is better then aluminum stuff, but hey thats just me. Then when temps stablize. heat sateration. See which material cools off faster.

hey Morph if U cant get the CNC code for different fins, maybe I can pass it on to a buddy of mine and see if he can get the code setup for ya. just an offer.
