Nice work... how come you aren't going for the "maze" style flow tunnels? They have been shown to produce lower temps, increased surface area. The swirl type ones, from the reviews I've seen, aren't as efficient... But nice stuff though!
I wonder how well "machining" with a drill press and vise would work? Prob not enough HP... I'd like to get something to machine copper blocks/stuffs with, but everything that I've seen costs a FORTURNE! My current block now, is a simple 6mm plate with longer plates soldered on it, then with a 2x1.5 copper end cap soldered on and brass nips etc... works decent, but nothing close to maze like blocks etc... Any advice would be much appreciated!
