Oh you have doubts?? How about a machine with a 12000RPM spindle?? You don't think I can drill 0.020" then? I'll be honest about the 0.006" that it would be extremely difficult but I don't think that small is very feasable. As for the copper block cost, what size is the block? I currently have a cutoff about 2.5" wide, by about 6" long and 1" thick. As for buying more I can get a good price. For the rest of the work, I wouldn't charge anything. Remember, I'm in this for the ideas and just want to cool my computer too! I would only ask that you pay for any shipping costs to send anything back and forth.
