How To Make A Tesla Turbine (Greenest Turbine)

Step 7 Put Bearings Onto Shank

When putting the bearings onto the shank just make sure to put some jb weld or some super glue on the inside of the bearing so it will not move once assembled, just put the glue on during the assembly process so everything lines up correctly. Remember that it will be spinning at around 15,000 rpm so if it would slip or run out of the bearing it would be very bad. These do not need to be put at any set position but when you do this make sure that they are not right up against the larger parts of the shank, I designed this so the bearings can have a little bit of room so do a dry assembly first to make sure everything fits then glue everything. And make sure that the bearings line up with the plexi-glass sheets you want them about centered in the plexi-glass, not too far in or too far out.

The problem with superglue is that it makes replacing the bearings close to impossible. Since you're turning the shaft yourself, put some grooves in it for snap rings to hold the bearings instead. And make the fit snug enough that you have to press the bearing on and it won't slip.

ok, I am in the design face of building one and I see that in one side the disk platters have holes and in the other side they dont...How many disks have the holes? or is the last one in one of the sides that doesnt have any...Very nice setup by the way!!

It is only the last disk that does not have holes in it. The rest of them do.

Want more power? Reduce the gap between discs to 1/32 of an inch to utilize the boundry layer effect. It will demand less pressure to achieve the same results without a load. For your age, you have done very well here. I did write an instructable with various information I wanted to share before I lost my internet connection to post anything more than directions that were very detailed. I wasn't published for the current contest giving away an Apple computer.
