To Morphling1: I think I saw that you cut the channels with a drilling bit mounted at a 45 deg angle, is that right?
MadDog: I was hoping to stay away from an off-center outlet. It's a good idea though, and I can visualize an upper chamber. I think there might be an issue with mounting the center barb, but that should be easily fixed.
I think I'll stick to the original idea. It also allows to "cheat the specs" with a lower block weight
, as they're measured without the tubing attached. the central barb will definitely not be brass, as I will stay away from galvanic corrosion, at all costs.
Fresno12: you've been pm'd! I might even be able to adapt this unit, with a little "top" redesign.
MYV65: Interesting. I wouldn't give the silver solder any points for conductivity. I'd have to attach all these fins with a temporary brace for this to work, since they make up 29 separate parts.
