Ok, thanks for the info. Can I pick up corrosion inhibitor at my local hardware store?
Next, Im completely new to designing custom blocks, so, if anyone has any suggestions/tips/tricks, to keep in mind, that you would like to throw out there, feel free to do so.
The basic plan, is to build a base plate out of copper, approximately 6" by 12", and 3/4" thick, with long channels running through it, and an inlet and outlet on one end. the channels will be open on one side, similar to a maze 3 design, with an aluminum heatsink(the same size as the base plate), with giant fins, perhaps from on old home theater reciever, or some other industrial component, functioning as the top plate, which will be bolted on, perhaps solder, all depends...
But here is the thing, I do not have access to any sort of milling/CNC equipment, just average garage tools. Drill, dremel, files, etc...almost everything except any kind of milling equipment. Any suggestions on how to make the channels in the base plate?
Edit: This is what I mean by channels, except the would be the entire length of the 6x12" base plate:
