Brad,

Ohh No!!!!!!!!!! I feel that that design is to hard to machine in copper, because of the small channels. You will have to use small diam. end mills. And copper is not machine friendly. You will destroy (man can I not type today, I hate feeling this way!!!!! ARRGGHH) more tooling. Which will in turn rais the cost per part. That is what alot of people dont understand about copper. It gets gummy when machined and sticks to cutting tools. Just ask Danger Den haw many carbide endmills they broke putting that o-ring grove in the maze 3 blocks.

When dealing with copper, Bigger tools= more strength which= longer tooling life.
