The block making process was a rather tedious one as we had no experience and all we had was a drill press. Add to the fact that we were working in very cramped quarters with bad ventilation. The number one mistake we made was that we did not using any lubricant at first. Thus drill bits and milling bits wore out so fast and thats when we realized our mistake and added some cutting oil. Here are some pics of the process.

The block is drilled with guiding holes before milling.

Heres me at the drill press controlling the milling with my hands.

Half done blocks.

The block on the right has a hole at the centre because I tried to make the base plate lower than 1mm. The one on the left is my friend's block.

The blocks before they went on a burning trip.

Here, my friend's block is being brazed with its top plate.

The hose barb goes on...

Heres my block being brazed...

2 "cooked" blocks. The black stuff is oxidized copper. They were left to cool on their own. I did'nt pour water because they may crack.

After filing, sanding, polishing and rinsing the insides with vinegar and water, heres my completed block.

No leaks at all, plus the fact that because its brazed, it can withstand higher PSIs that those soldered blocks.

Next, to put it on my chip and board...
