Basicaly it is just a drill press. Very simmilar to this:
Amd I even didn't use a xy-vise. I used two metal profiles 10 mm high fastened alongside the table,. So I could just fit the copper between them and it could move only back and forward. Then I fastened another metal profile across the other two, so the piece of copper could not move up. Then I just set the right hight of the table and pushed the copper forward as far as I wished and I got a nice groove. When I had one done, I moved the table to left or right (it can rotate around vertical axis) so I could made another groove next to the first one. And i repeated that so long and with different directions that I got theese waterblocks.
I know the aren't the most beautiful, but with the tools i've used making them... I think they're great
