JD: did you consider making the dimples deeper?
I think that you might be taking a performance hit, because of the mismatched diameters: the jet needs to be smaller than the dimple. Otherwise, the water in the dimple stays (essentially) trapped, and you end up with a performance that's on par with a jet against a flat baseplate, a la Swiftech.
Also, I don't think that you accounted for the return flow properly: your jets probably interfere with each other, because there's no tube to make space for the return coolant.
Your jet array of 9 or 10 should work. You might look into the brass plugs that we proposed for "Cascade": that might work out to be very easy to do. Heck, even the casing of a rivet might work!

Yes, on deeper. I mentioned that already. The OD of the jets is smaller then the ID of the demples by almost half. They just are not deep enough and the pipes are to small to only have 10. I need about 30 to keep flow up, but I havn't figured out how to pull that off with what I have.
Jet block 1 however wit hthe 9 pipes seems to have enough flow. I DO need to make the dimples deeper though. I am not even half way through the 1/8" base. I am considering makeing a 1/4" base with 1/8" deep holes and adding a 3rd row of pipes to make 12 pipes. this goes agains my goals, but my goals can't be achieved so I will have to adapt. Anyway I will try and run the 12 pipe version out on the laser today as I just tuned it up and itis cutting and engraving MUCH better than it has since I been here.
