Step 10Copper Air Input Instead of Plastic Tubing
Materials
-9" of 1/2" copper pipe
-Pipe cutter
-45 degree copper coupling
-90 degree copper coupling
-Air fitting
-Coupling with threads to fit your air fitting
-Torch
-Solder
-Soldering paste
-Mothers mag and aluminum polish and a rag if you want to polish your cooper
-Teflon tape
-Silicon
-1/2" fasteners for copper pipe
Ok to start we will have to cut our old tubing about 2 inches out. And since that tubing fits perfectly into the 1/2" copper pipe will just slide it right over the tube that is already there so we do not have to drill out our pvc and take the whole turbine apart. Now cut your copper pipe into the following lengths: 5", 3", and 1/2". At this point in time put some teflon tape around your air fitting and thread it into the copper coupling with the threads. Now take the 5" copper pipe you previously cut and put some soldering paste onto it and slip it into the other end of the coupling with the air fitting in. Now fire up the torch and solder these two pieces together.
Take the 3" piece of copper pipe and solder the 45 degree coupling onto it. On the other end of the 45 degree coupling solder the piece of copper pipe that is 1/2" long (this is for the plastic tubing to fit into; it will not be a snug fit into just the coupling so we have to do this unless you want to waste a large amount of glue sealing the two together). Then on the other end of that same pipe solder the 90 degree coupling on.
Now take the 5" copper pipe with the air fitting on it and solder that to the 90 degree coupling that is already attached onto the other pipe. The copper pieces are now all together.
(***Skip this step if you do not want to polish your copper pipe) With all of the pieces of copper together take some mothers polish (if you want to) and polish the copper (I prefer a shiny finish because it will draw more people into looking at what you have really done).
Now slide your tubing into the copper pipe and re-silicon anything if it breaks loose and also put a little bit of silicon inside the copper pipe in the 45 degree angle piece so it make a better seal. Now let this dry overnight. Now that you have done this your project will look much better. Also if you see the pictures with the tape on them it is just holing the copper pipe there until I get some fasteners. But if you have already gotten them fasten away.
