Help with creating a stable water seal?


Greetings all,

I've been spending the last few days building a home-made Tesla Turbine out of some random parts that I had sitting around the house... I've encountered something that I've found to be kind of frustrating in the process.

The design I've settled for runs on average hose water pressure... So to move along with things I need to create a water-tight seal to get as much performance efficiency as possible...

I've spent the last day now sealing and resealing this darned contraption over and over without success. I've used two different products - and instead of going through more chemical-messy trial and error; I figured it'd be better to just post a question here.

What kind of product would be best for creating a water-tight seal? I need something that will bond to plastic, preferably. Every person I ask gives me a completely different answer...

Anyways, thanks for reading.

Oh! My apologies...

The cakebox that I'm trying to water seal is actually the spindle for a pack of CD's. So it would be plastic.

I was actually thinking about trying that - I just wasn't sure if it would be better than marine goop or something...

Goop is what i would try, have used it on almost everything with good results. The type of joint will also make a difference. hope this helps some, good luck

Seals that are used to stop water intrusion for Shafts that are used for Turbines & Propeller, are Inflatable seals that are made of a durable rubber. For what you are doing, you have to figure a way to turn the turbine inside of the object, to turn a shaft for a Generator.

Oh yes! I know... I've already worked all of that out... The problem is that the pressures in play have popped the water at the base of the Cake-box. I went to home depot and poked around earlier... I'm going to have a go at it later tonight.
