Don't get too excited about the piuctures and forget to READ THE TEXT!
This is only a prototype or what you could call a "beta" version of the block, I made the mold in a hurry so as you can see there are some failures, as that "hole" on the bottom, another failure in the inside in the middle channel and some metal accumulations in the corners at the bottom of the inside of the block, those failures *will not be there* in the blocks that will come from next cast (wich will be the ones for sale) as I already figured out a way to avoid them. It's also dirty on the inside, it will be cleaned with a high pressure jet of air.
The inside surface is supposed to be that rough (except for the failures I told you about) to increase the contact area and water turbulence by a lot.
As you can see the quality of the pictures suck but that was the best I could get of my analog VHS videocamera.
The rest of the pictures I promised will be posted tonight.
The company web site is not ready yet so I uploaded the pics to my personal web space.
