yeah, good points about surface finish, and i'll probably stick with sandblasting because it's available to me free and it works and not too much of a pain.

my new design incorporates lower fin heights (only two levels, one 1/4" and next 1/2", and I may even lower those). (for reference the current block is 1/4, 1/2, and 3/4 inch long fins)

I was thinking of going around .090 in. base for my next block, (copper) which is about 2.3mm. But then I want to put dimples in the base (basically half of a sphere), effectively dropping portions of the base thickness down to about .058 in. or 1.5 mm. I think this would be MUCH better than what I have now, as 1/4 is much too thick. I also expect higher flow rates with my next revision, hopefully something like 5gpm (300 gph) through ALL components when complete.

I will post some design pics in a few days maybe when I have more time to get all your help and thoughts on it...
