Thanks for the input guys.

how about having a central inlet, with a southwest exit, like shown, and a northeast exit, with two sets of channels. it's probably spread out the water flow a bit more

Brad, you really like the 2 outlet idea I take it
(I've seen your post with your 2 outlet designs). Would you put 1/2" in and 2 x 3/8 out? If you did that would it make sense to take each outlet to a different rad? Veeeery Interesting...

After doing some calcs, it's actually worse than I thought. Based on even sized channels for the "arms" radiating from the center and a smooth increase in size from start to end for the outside channel, here are the relative flow numbers in percentages, with Arm1 being closest to the outlet:

EMC,
Thanks for running the calc for me. How did you do it? Is it really complex? Given your calculations, what if I went to a 1/4" thick block with 1/8" channels? Would that be too thin? That way I could keep the volume of the channels much lower. Another idea would be to reduce the number of channels from 8 to 6. Also, would doing what redleader suggested going to larger channels farther from the outlet and making them progressively smaller as the channels approached the outlet make a difference? I.e. Channel 1 would be 3mm and channel 8 would be say 5mm wide?

Last thing - the pic I did was to go on top of a block. If you didn't already, look at the link to the original sight that Digital referenced at earlier in that thread. In your case, all the top would be is a rectangular "box" with 8 holes drilled in the bottom to feed the output of the arms up and 1 in the center for the inlet pipe to go through, then the "top" has 2 holes, one for the inlet, one for the outlet. Not really a hard piece to make at all. Just a box with holes in it After looking at the ratios needed for balance based on your original block design, this alternate way would actually end up being much easier.

The reason I thought it would be harder is you would end up having to mill 3 pieces of copper. One for the top with the inlet and outlet, one for the "box" with 8 holes in it, and 1 for the channels. I guess milling them wouldn't be that big of a deal but getting them all put together again would be. My soldering skillz are worse than my Illustrator skillz!!!
BTW, if I did go this route how thick would the "box" have to be to allow optimal flow through to the outlet?
I appreciate you guys helping me think this through. This has been a great learning experience. Hopefully by the end of this I will have a great performing custom WB!!!
