So far all I have used is a hand drill and a dremel. I'm now confident that if I had enough time and patience I could make a white water like block with just these tools. I must say that it has NOT been fun so far, though. The drilling takes a LONG time and I HATE soldering. That's why I'm not showing the top of the top plate (UGLY).
Anyway, to make the groves (which were really just an afterthought to increase flow through a very restrictive design) I used regular cut off disks. I think they're 3/4" or something. The ones that come in the little tubes. Anyway, that part is easy if you have a steady hand.
Keep in mind that these parts are not cleaned up. The finnished product will be ugly anyway, but I'll show it when I'm through. For this one I'm going to seal it with JB weld. The next I will try to solder together.
Here's the pic:
