Tesla CD Turbine With Scary Steampunk Laser PumpkinCutter Attachment

Step 5 CD Case Mods

This is how to to modify the CD case to accept an inlet jet nozzle. My first turbine used a 1/4" outlet barbed brass fitting with 1/4 "pipe threads for the nozzle. I used a couple of pipe adapters to go from that to the female garden hose coupling and shut-off valve. I can connect garden hose water pressure directly to this shut-off valve, or switch to compressed air with appropriate fitting.
Make the jet nozzle by using a 1/4 " outlet pipe fitting and crushing the end to form a thinner wider orifice. It takes a little finesse, but hot-glue works well to stick the jet nozzle onto the CD case. Carefully cut a small hole in the side of the case to accept the nozzle, then position the nozzle at approximately the same angle as shown in the pictures. Start building up the hot-glue, a bit at a time, to keep the nozzle in position. Take your time and allow the glue to cool somewhat as you go, so as to not warp the case. Cut or grind the nozzle end flush with the inside of the CD case. Allow everything to fully cool and cure, then add plumbing fittings to adapt to the shut-off valve. Put the previously completed CD Disc pack on the spindle, and install the modified cover. The CD pack should freely rotate. If not, find out what is binding and grind or cut to suit.
Alternately, you could use a plastic nozzle, instead of brass, and glue it in with hot-glue in the same manner. I used a tapered ABS fitting in the CD Turbine seen below.
