With the price of copper today I'm not surprised that there are not many people offering to make copper heat sinks, I am about to limit the
ones I will be making to certain sizes because of that very reason, the cost of copper now, I have been working with a large stock of
copper I bought some time ago before the price went up and I been giving people that price all along

and now it's at a point
when I replace my stock it will cost so much the price of copper heat sinks will go to a point that people here will not want to pay
for them I think, we'll see tomorrow when I go to buy a round bar of 1.750" Cu.
