I'm sorry, that I can't present the finished columsn. I decided to make the missing parts. The first pictures shows the small insert to fast the column on the bottom or top plate of the reservoir. I also make some of the inner parts of the columns. The last picture shows the finished parts. I have to make some more. If I have all parts I will start with the missing steps.
I will try my best, but it will be diffucult to deliver weekly updates for me. Today I had the chance to make the slot in into the columns. The next steps will be to file the slots to get it into a rectangluar shape. After that I can assemble them and drill the holes for the illumination. Enjoy the following three pictures. I'm not sure if I can make a additional update within the next few days, because I have to mod a fractal design case. This case is the new home for my media home server. I also have to design and build a couch table and TV bench. At the moment the other projects have a higher priority.
