This step is for the installation of the light pipe into the Lower assembly, it should be noted that you must take EXTREME CAUTION while doing this, as the light pipe is a pain to bend and there are a number of smaller portions of the reactor that are susceptible to easily breaking.



The first thing to do is paint the lower assembly with a god coat of chrome silver, let that dry for about a day!



Next thing to do is cut the 4 segments of light pipe, each segment has to be approximately cut to 11.2 cm, any shorter and it may not catch the holder, to long and you will not have room for the LED's. Fortunately, too long can be corrected with some trimming, just be sure to not cut it too short.



Once they are cut, it is time to install them, again i must state that extreme care must be taken not to damage the lower assembly, ( rest assured, I am working on a stronger version ).

First lets take a look at the lower assembly, I designed the part so that there are two clear end, which are the ends with the supports on the top. Start by inserting each segment individually, with one end inside of the support, thread the pipe carefully into the other slots by holding onto the other end, going in at a 45 degree angle you should be able to slip the other end of the pipe into the support on the opposite side of the reactor. Doing this individually you will be able to get all 4 segments into the array without damaging it, though usually there will be excess material inside of the slot where our LED's go. Not to worry though it is something we can trim



Using a Dremel tool with a cutting attachment, carefully trim the inside of the slot so that you maximize the amount of space for the LED's



Once it all looks good, the lower assembly is done!
