With the new limited area design can you drop down to 1/16" roughing mill bits Jaydee? Could have 16 pins with nearly the same surface area as the larger diamiter pins. And with the smaller pin area would take no more time in machining, or at least not much.

And if you were to use those bell shaped inlet/outlets as in your last Lemon copper block you could use one that would give a velocity boost just befor going into the block.

And, depending on base thickness perhaps a few dimples with a drill between the pins to further increase surface area and improve turbulance.

I relize your goal is high flow + ease of making these. But the roughing mill would not add a great deal to machine time would it? Same with dimpling the base.

And with the limited pin area the flow should still be very high.

Edit:

Possible alturnative, 3/32" roughing mill bit? I'll be quick to admit I don't even know if this size is offered.

Wish I had a mill and space to set it up. Has to open up many interesting chances to tweak things, and play with design.
