Build an Amazing Tesla CD Turbine

Step 5 Finish Nozzle and Attach PVC Pipe

Continue building up hot-glue until the Nozzle and Nozzle Extension are well secured to the CD Case. There should be no glue on the inside of the Case. The Nozzle Extension should have been cut flush with the inside of the Case, giving an oblong shape to the nozzle jet opening. The Nozzle should be well supported by the build-up of glue on the Case by now. Allow the glue to cool.

Now it's time to attach the 2 foot piece of 3/4 inch PVC pipe. Sand each end of the pipe to clean it, then use the PVC primer to prep. Add PVC-to-ABS cement to each fitting and pipe end, and twist together to connect. Let the cement set for an hour minimum. Here's an instructable for more info on cementing PVC.

Attach the Garden Hose Shut-Off fitting to the fitting on the end of the PVC pipe.

The Nozzle and CD Case Cover mods are done!

so I attach a tubing smaller than the nozzle, so half of the water goes throguh the nozzle to the cd thing, and the other half goes through the tube and to the cd thing. like im dividing the water right.

All the water goes through the nozzle extension tube. The extension tube simply increases the speed of the incoming water by reducing the diameter of the nozzle down to less than 1/8 inch. The extension tube should be a tight fit in the nozzle, glued in. My last turbine didn't use an extension tube because I used a different nozzle that had a smaller than 1/8 inch hole.

so i have the option of trying to find a smaller nozzle aswell? i have a pretty small brass sweeper nozzle.

Ok, if the opening is round and about 1/16 -1/8 inch that should work. A rectangular opening works better because the fluid contacts all the discs, so you could consider crushing the tip of a brass fitting to make it a wider, flatter nozzle.
