Step one; just like in our version one system we install acrylic plugs into the ends of the tubes with acrylic bonding agents. But we then double dip the tubes into the plastic dip to seal them and make them shock resistant. We waited about 10 minutes between dips as per the instructions. One thing I found that was a disappointment and I sure hope your reading this; plastic dip off gasses a lot! If you do not cover the holes at the ends of the tubes with masking tape it will leak into the tubes. As it cures it will actually rupture your tubes. My array here was originally an 8 tube array… I salvaged 3 from this mistake that I masked “just in case”.

We drilled holes for the hose fittings to protrude as well as the larger holes for the tubes to seat in. this is straight forward work, however one tip to pass on is to drill / cut them in pairs just incase your measurements are off. This will maintain a consistent rig.

Here is the cut and prepared sets of ends. Each end uses both pieces.  Make sure you allow space between each tube in your measurements. The inner hole is one inch to allow for a socket driver to access the pipe fitting if needed. The large hole is a 4 inch hole saw. This allows room for the plastic dip coating.

Assembly is super easy and straight forward for this build. Here we have the array upside down for ease of assembly. Make sure you predrilled each hole on the side pieces before you screw the pieces together. One tip here if you don’t like to measure or are in a hurry is to put the two bottom pieces together and install a tube to get the height of the bottom…

Here we can see the top view partly assembled. It’s important to point out here that you can see the holes for the air lines in this array now.
