it needs to be Cu 110 grade or better
and sheets might not cut it, seeing as you want a good amount of weight in the base to keep the heat from swinging wildly. probably .5-1 inch thick base and the heatpipes are going to be hard to construct.... Fins are easy to make, just thin sheets of copper with holes on each side, punch the holes so that it leaves a 'spacer' for the fin above it or just use regular washer/spacer stacks. simple
I think he would need to do some research on how to properly construct heatpipes - they have some kind of special gas in them...
