Build an Amazing Tesla CD Turbine

Step 2 Design an Inlet Nozzle for the CD Turbine

This is where the rocket scientist in you comes out...what size, shape and angle inlet nozzle should the CD Turbine have? There will be many theories, but the facts are... WHATEVER WORKS!

I have tried several different types and materials...they all worked. There's room for experimentation here. You just need to taper down to about a 1/8 inch hole into the side of the CD case with pipe fittings, or plastic pipe, then hot-glue it all in. ( Pictures in following step.)

I used an Orbit WaterMaster Extension Nozzle Model 91129 from Home Depot for the Tesla CD Turbine II nozzle. The Orbit Nozzle has an advantage of being able to use a long 3/4 inch PVC or ABS pipe with the included fittings. One fitting is a tapered nozzle, and was originally used for burrowing under concrete sidewalks with water pressure. The other fitting connects easily to the garden-hose Shut-off Valve. A 2' piece(or longer) of PVC connects the two Orbit fittings.

Note: Brass fittings and copper pipe could be used for more of a steampunk look.(future instructable!)

A Later Note: My newer instructable makes the nozzle install process much easier!

could you use a water balloon nozzle

A water balloon nozzle will likely be too big. The CD Turbine nozzle inside diameter should be no more than about 1/8 inch hole size.
