How To Make A Tesla Turbine (Greenest Turbine)

Step 6 Cut pipe and Drill air inlet

Cut your pvc pipe to 2.2" and then drill a hole the size of your tubing into the middle of your pvc pipe and offset it a little bit so it is at an angle so that when the air enters it, it immediately starts spinning inward. Once this pipe is cut to make sure the whole end surface is even, take it on the lathe and face it off until smooth, then take some 600 grit sandpaper and smooth the ends so no air can escape when the plexi-glass is put onto the ends. If you want to skip the sanding then just put some silicon or mopar sealer around the ends to keep the air from seeping out. On my project I did not do this, I just sanded it because in my opinion it gives it a better appearance. This step is pretty self explanatory.

I will be building one of these. center and mount plexi on lathe, groove .003 or so section for receiving PVC turbine housing, carefully dribble small amount of acetone into groove and press in PVC. Once clamped with bolts it should be totally air tight. It may also be possible to groove the end of the PVC to receive an o-ring, if the proper size can be acquired, shouldn't be to hard so ultimately that is most likely what I will try to do first. Acetone will be plan B. Nice job on the Instructable and thanks for the inspiration. I read about these years ago but never thought to build my own, until seeing this.
