If you wanna build something high tech, truly scary, cheap, and relatively easy for Halloween, this Steampunk Tesla CD Turbine is it! It uses recycled CD's, Neodymium magnets and a Magnetic Coupling to power tools and implements.

You can order the BEST neodymium super-magnets here:
http://www.kjmagnetics.com/default.asp?PARTNER=mrfixitrick

From experience, I can tell you that it's scary enough to be running a high-speed turbine made from recycled CD's, supermagnets and glue. But running it with a magnetically-coupled Skilsaw blade, now that's TRULY scary! I would not advise anyone to try this. I only did it to prove a point or two, and they haven't quite made this alien technology safe yet.

This Tesla CD Turbine incorporates many subtle and amazing feaures, such as shaftless, bearingless, magnet-separated CD discs driving magnetically-coupled attachments to high speed.(huh?) More on that later.

The CD Turbine works on either compressed air or water pressure. It's cheap and easy to put together, lots of fun and makes cool sounds to boot.


Pumpkin Cuttin' Ceremony with the CD Turbine.

However, the PumpkinCutter Skilsaw Blade Attachment has a big element of danger ...for both people and pumpkins! Don't use it!!...I only use the Saw to draw attention to the wonderful attributes and power of this little CD Turbine device, and things got a little out of hand. I promise to never, hardly ever, do it again. (There was an unrehearsed Pumpkin Cuttin' Ceremony on Halloween, of course...hehe)

I have discovered that this is not a project to take lightly. (With humour, but not lightly.) Under water pressure the Tesla CD Turbine spins a couple of thousand rpm, but under air pressure it is a high-speed dangerous device that must be treated with utmost respect.

Lets remember, folks, this thing is just a CD case, CD's, and magnets. And glue. Lots of glue. (...and keep telling yourself that when you see the magnetically-coupled PumpkinCutter Skilsaw Attachment smoothly wailing away at way-too-high rpm!!)

This device is built for working demonstration purposes; to prove ideas, not for longevity and everyday use. Hence the danger factor. (i.e. yes, things could self-destruct at any time...hehe)

I can really only recommend building one of these with the PumpkinCutter Attachment if you are a truly dedicated experimenter, and promise to wear your suit-of-armour and carry a shield, and cower behide a far-off wall.

We can, however, make a "point" to have some real fun with something a little less on the leading "edge", so to speak. So I suggest to perhaps substitute a Nerf disc for the sawblade! or use a Frisbee! maybe make a CD Turbine-powered Frisbee Impeller?

When the world comes back to stone age, i think you will be treated as a king!
mrfixitrick (author)  hayme3 years ago
Haha, too funny!
Yeah.... in case you had not noticed, there is a whole heap of safety features on most circular saws / drop saws / compound sliding mitre saws etc....

All of them have everything to do with keeping the rotating or stationary blade covered at all times, except when it is actually cutting.......

While it might be "Oh So Wicked" - this is REALLY dangerous....

Everything about it is REALLY dangerous....

The saw spinning in free air, the whole driving mechanism, the mounts for the blade - everything....

I am not into making overt threats, but if you came around me with this, I'd be putting my health and well being at a much higher value than yours.

I tend to regard this as the drunk driver, on the wrong side of the road, and through a crowd of pedestrians kind of very bad idea.

I don't know how fast it will spin up too, but if it disintergrates at high speed and throws the blade, you could be in deep trouble.....

Industrial Occupational Health and Safety - this just presses ALL my big red buttons..

Google - Images. "circular saw" injuries

http://www.drbadia.com/near-amputation-of-forearm-from-saw-injury-agustin-acosta-radio-journalist-testimonial-id-11-eng.php

Agustin Acosta is a 40 year old radio journalist who sustained a nearly complete amputation of the distal forearm when a circular saw blade accidentally spun out of its housing on new year's day. He was taken to the OR as an emergency where the arm was reattached using a steel plate and screws and bone from his pelvis as graft. The extensor tendons and the critical median nerve was also repaired. After a long course of rehabilitation, he has regained full strength in the arm and has near normal sensation. He is a good example of how much function can be regained in an exceptionally motivated patient

wow this is awesome can this cut through metal easily
mrfixitrick (author)  tinker2342 years ago
It has a sharp carbide blade that is meant for wood...and pumpkins! However, if the metal was aluminum and the blade going really fast, something will give. ;)

A metal-cutting disc like welders use, would work much better.

Actually, using the correct tool instead of this hot-glued together contraption would be a whole lot safer!! (but not nearly as awesome!)
yeah so with the right blade i could cut through light metals
mrfixitrick (author)  tinker2342 years ago
Yes. The limitations are more that the magnetic drive can only take so much torque, and getting enough air pressure and volume to develop adequate speed and torque...
ok thanks
pjkettlejr3 years ago
Could you place coils of wire above the magnets and make this into a generator/alternator? I suspect that getting 12 V out of it would be about the max, but if you had a 'free' source of water like a spring house it would be capturing energy that would otherwise flow to the beaver pond.
mrfixitrick (author)  pjkettlejr3 years ago
Yes, this can be done. I have recently made such a generator that can light 50 LED's form faucet water pressure in a 2 inch Tesla Turbine.

This is the instructable of the day today. Congratulations!
mrfixitrick (author)  Hitchtopher3 years ago
Thanks! It is humbling to have an older instructable come back to life on the main page, but this one is kind of a classic, I guess!

I have known about Tesla for a while and I know about his inventions of the Tesla Coil, the electric motor, and telemechanics. But I had never heard of a turbine made by Tesla, so I looked it up in my dad's giant book with all of his patents and there was a whole section about his turbines! Thanks for introducing me to a new thing!
mrfixitrick (author)  Hitchtopher3 years ago
I'm glad to hear you are learning about the Tesla turbine...there are good reasons why Nikola Tesla called his turbine," the greatest of all my inventions."

Tesla really believed that his turbine would "make scrap of all the heat engines of the world" ! (...and maybe it will someday ;)
mbear3 years ago
OK, this is going to sound silly, but for the life of me I can't figure out where the water goes into the turbine and comes out again.

Does the water enter the system along the outer rim of the turbine (the CD) and drain inward towards the spindle or does it go in at the spindle and flow out along the CDs?
mrfixitrick (author)  mbear3 years ago
It can take a while to get the "hang" of the Tesla Turbine. It seems too simple to work!

In the Tesla Turbine, the fluid enters the outer rim at high pressure and velocity, and exits out the centre (spindle) exhaust hole, imparting its energy while passing through the discs. The discs behave like a motor.

In the Tesla Pump, fluid enters the centre inlet (or spindle) and exhausts at higher pressure at the outer rim. In this case, the discs are driven by a motor.
I'm interested in just building the turbine this is awesome. looks more intimidating than it does lethal i like it.
menahunie4 years ago
Why not put the magnets closer to the cd hub?
Wouldn't it still work; but there should now be allot less g-force on the magnets like when they are on the rim as before?
Might allow higher rpms before failure?
mrfixitrick (author)  menahunie4 years ago
If the magnets are closer to the hub, it seems like it would provide for higher rpms. That's not always the case, as the magnets can act as the washers that Tesla called for and help with starting torque by interacting with the fluid.

Also, some of the devices I run require a higher torque than inner-mounted disc magnets can provide. The torque delivered by the magnets before slippage is determined by the radius and number of magnets.
Ekzile5 years ago
you talk about letting the pressure build up would it work with like Co2, compressed air or something.
mrfixitrick (author)  Ekzile5 years ago
My Tesla CD Turbines will run on any source of pressure that doesn't melt the hot-glue. Compressed air works great. Or water pressure...or both!
(see "Tesla CD Turbine Test Combining Air And Water" )

The CD container can take up to 120 psi, but any restriction on the output exhaust will cause her to blow, capt'n! As I found out in one of the following movie..."Tesla CD Turbine Bursts on Kitchen Table"

I tried a paint-ball canister briefly; it worked, but needed a proper regulator to control it.

A proper Tesla Turbine can burn any fuel, or run on any source of pressure. The disc turbine design is the only type of turbine that can do this.
How about a turbine using a home made combuster like you see people do in converting a turbocharger to a turbine?
Instead of using the impeller made one using high temp S.Steel disks and see how fast it will spin?
You could use an output shaft with a gearbox to gear it down.
Or use the output gasses from a converted turbocharger to run the tesla turbine?
mrfixitrick (author)  menahunie4 years ago

I have a goal to build such a turbine in the near future.

Ceramic nanocarbon discs are best, but very expensive.
My turbine will be able to run off the gasses produced from a plasma furnace combustor. It will be virtually pollution-free, and in best case scenario will require no exhaust pipe.

I expect to build a Tesla turbine that has no bearings, no shaft and no seals to contend with. Now there's a challenge!
If you were driving, held it out the window, and funneled air into, would it work? I wouldn't think so. but I had to ask. Also, could it work on vacuum power also? Another thing I just had to ask.
mrfixitrick (author)  nomooremr.niceguy5 years ago
On a good day with a low-friction CD turbine, I can blow into it and get 500 rpm. That's probably about one psi (pounds per square inch) In the case of funnelled air, it will increase the velocity, but the actual pressure won't increase much. There will be about a 1 psi pressure increase at 200 mph, for example. The turbine won't go very fast on 1 psi, and will have low power. The CD Turbine could work on vacuum power. It would work best to hook up the intake of the vacuum to the outlet of the turbine and the nozzle of the turbine to the vacuum's exhaust. The heat might be a problem. It still won't be nearly as powerful as 120 psi compressed air.
Ok. Thank you.

Hey, on second thought, perhaps it is me who does require a new photo...after all that was last Halloween. Hmmm...I was thinking of a suit of armour...
Suit of armor would look excelent... If I may make a suggestion? With this pumpkin cutter? A steam punk outfit would look nice... League of Extraordinary Gentlemen like.
mrfixitrick (author)  Ph3nomin0n6 years ago
Good idea...thanks! Now that I've looked up what they are, I'd love to be part of the League of Extraordinary Gentlemen !!
That movie was interesting. I would like to be a part of it too. Now I just need to make the turbine...
mrfixitrick (author)  Kaiven6 years ago
You can build a basic turbine for about $10 or even less without magnets. It would be about $60 for parts to build a more serious version with bigger magnets and magnetic coupler.
Oh, because of my other comments and my spammed comments on your Youtube videos (whistles very loudly to self), you probably know I am working on it. So far, no money used :D

Well, it was Halloween, after all! The costume was my Bunraku puppetry costume generally for use against a black backdrop. I figured it would be good at Halloween, so folks watching would be as scared as I was when I ran this Tesla CD Turbine with "The Blade" for the first time, with no dress rehearsal...and no bandage dressings! ;)

Next time, use a flame thrower as input, or gasoline, or rocket fuel, or lemmings running down the tube...
mrfixitrick (author)  nomax6 years ago
I was thinking more in the lines of HHO (electrolysis of water, H2O, into Hydrogen and Oxygen using a plasma arc,) Burn the HHO, the resulting energy and implosion reaction could provide force for moving the fluid. Lemmings would add a certain quality to the process, though. Their attempts at experiments in anti-gravity are to be commended!
flamerz146 years ago
Great instructable! I wonder though, for the water outlet, can I just put another hose fitting on the opposite site of the inlet?

Great instructable =]
mrfixitrick (author)  flamerz146 years ago
You could do that, but it won't work as a Tesla type turbine. It won't be as efficient because the fluid should be in contact with the discs as they rotate for several rotations, then the fluid is to leave through the center location, after moving in a spiral manner to the middle. One advantage of your idea is that the turbine would be reversible with proper construction!
dontno6 years ago
I'm all for innovative "Ibles." However power tool safety seems lacking. I was taught long ago never wear loose fitting clothes, sleeves rolled up, and above all don't wear gloves when operating power tools. Also there should have been a blade guard installed on the saw. I'm not knocking you, but just want to point out to others who may want to build this "Ible" of the safety considerations. Great job on the use of the Tesla turbine.
mrfixitrick (author)  dontno6 years ago
Domtno, Thanks for your safety concerns. Hopefully, not many people will consider building this unit with the saw blade! I cautioned against it several times, such as... " I can really only recommend building one of these with the PumpkinCutter Attachment if you are a truly dedicated experimenter, and promise to wear your suit-of-armour and carry a shield, and cower behide a far-off wall." and, "We can, however, make a point to have some real fun with something a little less on the leading edge, so to speak. So I suggest to perhaps substitute a Nerf disc for the sawblade! or use a Frisbee! maybe make a CD Turbine-powered Frisbee Impeller?" and also, "I would not advise anyone to try this. I only did it to prove a point or two and they haven't quite made this alien technology safe yet." I admit I should have used better safety gear with testing this new machine. However, I don't agree with your sleeves rolled up, gloves off approach to safety, and here's why. It's inviting a sliced artery, or CD-rom shrapnel stuck in your arm. Exposing bare skin to possible flying CD bits and/or fractured magnets is not a proper approach to safety in this case. Your approach works well in a controlled shop environment with powerful but slow-moving rotating tools, such as lathes or drill presses. So I say, wear leather gloves, and the heavier the better. Wear several layers of thick clothes so that flying debris is caught up in the clothes, not in your arm such with thin tight-fitting clothes. Leave sleeves down, again using several clothing layers. Motocross or hockey armor is even appropriate. (I should have used leg armor and a cup for the Pumpkincutter test!) Also, a face shield is a must, not just goggles. I now use a 1/8 " steel or polycarbonate barricade around the tool when running on air pressure. The danger is not about getting tangled up in the machine, like with a drill press or a lathe. The danger here is getting hit by sharp stuff coming apart at high rpm. By the way, I did use a blade guard from a skilsaw. It's the metal part that you see on the CD Turbine saw. It's not retractable, true, but I believe that would have made the difficult pumpkin cuts more dangerous. Besides, the blade wouldn't look half as scary with a wimpy guard! hehe

hey, what if you put some sort of lube on the spindle? would it work better?
mrfixitrick (author)  FunkNattidelic6 years ago
Yes, it helps, especially if the discs are not perfectly aligned. I have used both silicone spray and high-tech natural sheep lanolin lube. I'm going to stick with something other than the sheep stuff, cause it stunk...literally! When the discs are balanced well, there is little wear on the spindle post. The polyethylene spindle post self-polishes from the rotating discs. When using with water pressure, there is virtually no wear because of self-lubricating and cooling properties of water. Also, the disc pack mysteriously rises under pressure, so very little friction on the bottom, where I place a couple of loose CD's sprayed with silicone. Some lubricants will destroy the layers of the discs, or affect the glue. Don't use auto grease, for example. Note: A food-safe lubricant should be used if outflow water is used for human consumption!
cool. thanks.
JasonDMX26 years ago
Any two of the rotating surfaces rubbing against each other would constitute the definition of a bearing.
How much torque does this have? and would it be able to use power from steam or would it melt? (I am considering making a steam powered version of it to generate electricity)
mrfixitrick (author)  Frogotten_One6 years ago
I estimate that torque would be in the range of a an inch-pound or two for the air-powered CD Turbine. So, at 5000 rpm that would be about 1/10 horsepower.(a normal Skilsaw has about 10 times that.) This value is increased with more psi pressure or volume (i.e. more nozzles & more discs)

Using traditional steam in the CD Turbine is out of the question. I tried with a steam kettle, and warped the plastic discs in seconds.

Tesla, however, used steam in his turbines, the smallest being 100 horsepower. He even had one that ran on gasoline. For best info on this, consult this excellent [http://www.frank.germano.com///teslaturbine.htm Tesla Turbine technical page.]
How were you able to power your turbine? Do you have any suggestions of how I could power mine? How much power was generated when you used water to power it?
mrfixitrick (author)  Frogotten_One6 years ago
If you build a Tesla CD Turbine, similar to my last instructable, it can be run on 40 psi faucet pressure. It won't have a lot of power; the turbine will only rev 1200 rpm on regular water pressure, even less with a load.
Somewhere between 1 and 50 watts is likely, depending on all the variables.

Now, say, hook it up to a pressure-washer at 1500 psi and it will produce maybe 10 times that power and rpm...until it blows the CD case!

Or run on 120 psi compressed air pressure, but be careful to regulate down 'cause in about 3-4 seconds at that pressure will over-rev the CD's to 20,000 plus rpm and literally explode them.

There may be a way to make steam increase the cold water pressure, so giving better performance from the turbine, but generally, heat doesn't work with the CD's. (besides, it will melt the nozzle hot-glue!)

Does this model work as a very good water or air pump? I know tesla could use his for air and water pumping. And if so could you use one cd turbine to power another at some distance away via an air tube?
mrfixitrick (author)  Frogotten_One6 years ago
Yes, this will work as an air or water pump, with little or no modification. It won't be efficient without designing it specifically as a pump, and there are limitations due to the nature of the materials involved. The 5" CD discs need to rotate above 10,000 rpm and preferably up to 25,000 rpm to develop enough air pressure in the turbine case to drive another turbine through a hose at a distance. It would probably require about a 1/2 horsepower motor to turn the driver turbine. Maybe use a disc grinder, magnetically coupled for example. However, the CD's normally would explode at 23-25,000 rpm, and possibly at 15,000 rpm with the magnets attached as in my model. That is problematic, to say the least. I will stress once again that this unit is capable of over-revving easily in a few seconds on compressed air, and exploding. Running the CD Turbine on air is like running with scissors...sometimes you get away with it!
Could be made completely portable using this on a smaller scale - say, with a paintball gun-sized tank.
mrfixitrick (author)  BorisTheSpider7 years ago
Yes, right on... thanks! Paint-ball one might work for short blasts, good idea. I actually tried a super-squirter just pumping air in and got a few revs, but it took 200 pumps!
I don't know what kind of air consumption this thing has, but from what I understand, the CO2 tanks hold quite a bit, since it's stored in liquid form. After looking at that ible again, it actually looks like the tank used may be suitable. It would be a bit large (much smaller than I originally thought), but you could always strap it to your back. And he said when it was half-empty, he managed to change four tires, fill them with air, and still have some left. And that was using power tools. I'm willing to wager that there's some happy medium ground this thing could get going at that would give it long life and good power. Maybe I'll try to get one built if I ever find some of that "free time" I hear everyone talking about.
mrfixitrick (author)  BorisTheSpider7 years ago
Good ideas. I will be trying more stuff with air pressure after I build my new bullet-hopefully-proof enclosure around the case of the air version of the CD Turbine. Once I'm satisfied I'm not going to poke my eye out, I will do some portability experiments with a pressure tank. The CO2 is good for volume and pressure...it's more a matter of the correct regulator, and also cold temp/icing problems.
Great call with the bulletproofing. Always a good idea to keep all fingers and eyes intact. Can I ask how you intend to achieve that? I'm thinking about it and coming up with bupkis.
I hadn't even thought about icing being an issue, but I guess that would make sense with CO2. I'm sure some of that may be countered by friction heat, but maybe not enough. I suppose only experimentation (or a ridiculous equation) will tell for sure.
The regulator should only be a minor headache, though. I'm sure it can be had, it's just a matter of finding and acquiring it.
Well, good luck, and as always, I'll be watching you Focker.
mrfixitrick (author)  BorisTheSpider7 years ago
haha...You hit the nail on the head with saving humanity from the ordinary, but anyway back to body parts. I just bought an expensive piece of 6 inch polycarbonate tubing, with poly 1/4 inch end plates, in order to do some "testing". I want to show how to make this thing safe for use on air...first I must prove to myself! Either this or rev limiter; this better I think. Maybe both.
Yeah, that's a great starting point at the very least. It should really limit digit loss for sure, and without getting into more technical aspects than build materials. It's always a good idea to only change one variable at a time, also.
I'm not sure what the purpose for this is. It does look cool, but it seems like a lot of work to make. I'm not being negative - you've obviously spent a lot of time on this. But is it supposed to do something?
It's almost a sort of proof of concept. Proving Tesla's turbine does in fact work, and also proving it can be made extremely cheap with household items. It's almost like reinventing the wheel. It's not going to save humanity from anything...except the ordinary.
But then again, with some modifications, it can actually use energy that is otherwise lost, create a new source of energy, and look extremely cool. I highly recommend you see the kitchen version for some more details.
mrfixitrick (author)  thomasedisonjr7 years ago
Now that I've figured it out, it is very simple, cheap and fast to make, and I could train a 10-year old in minutes how to build one in an hour. The device has many, many purposes, because it is adaptable like the electric motor is adaptable. I do movies of fun experiments in magnetics. In the instructables, I show somewhat practical uses such as stirrer, blender, salad spinner and game spinner. Not to mention PumpkinCutter. It's most important use will probably be as a Steampunk Parlour Room Energy Oscillator/Rejeuvinator, however.

Nyanman7 years ago
what is the maximum pressure that the device can withstand? i'm really tempted to try water at 55,000 p.s.i. in it to see what happens. will it survive?
mrfixitrick (author)  Nyanman7 years ago
It's encouraging to see someone even crazier than me, but no, it will blow up like a balloon and burst. Where will you find that kind of pressure ? That's the exact same pressure used to cut metal plate with water, in fact it 55,000 psi could cut 1/2 inch thick titanium at the rate of 7 inches per minute. I bet that's where you work??
mrfixitrick (author)  mrfixitrick7 years ago
On the other hand, if the jet nozzles were really, really tiny and directed at each disc, and the spray pattern altered to fan mode instead of slice, you might have something. I will try it with a 1500 psi pressure-washer...now that could be interesting! I will be making a portable unit with a high-pressure air outlet. The CD turbine will take about 200-300 psi air max before blowing up, I predict. The main problem is it revs so fast at high pressures that it will explode without a load.
explode w/out a load? that could be entertaining. i think ill have mine custom-machined out of titanium or T6 7075 aluminum. might survive then. and, film it when you use the pressure washer so you'll have a cool video for youtube!
gotcha.
i dont work with one, im only 14, i just built one myself out of a hydraulic pump and a car engine(old v-12). so yes, im crazier than you. =)

and you need some abrasive for maximum efficiency when cutting titanium. either way, it works VERY well. maybe i should put it in an instructable.

Dr_Acula7 years ago
Just a thought but if (when) you cut off your thumb or finger with this, be sure to tape it to your forehead before you pass out from blood loss. That way, the paramedics won't waste precious minutes looking for the missing digit. Seriously, it would be interesting to pair this with a homemade alternator like the ones used for homebrew wind turbines. High power magnets, air core coils - ie a good match for a high speed low torque turbine. It would be great to see how many watts it could produce.
mrfixitrick (author)  Dr_Acula7 years ago
Thank-you for both of your perceptive suggestions. Best prevention re fingers no doubt just tape 'em all up to my forehead before testing! Q.If I cut off my head, do I tape it to my hand? I've thought about alternator...I have an auto alternator I'm rigging up right after the Meatgrinder and the Blender magnetically-coupled attachments I'm currently working on.
instead of digits removal, just buy a cheap robotic arm and attach this to the end. then, after programming it so you have contro through a teach pendant, stand far back and have fun! or, check out the wiigobot. older robot arm from factory+wiimote control. wave the wiimote, and when you stop the robot duplicates it.
wow dude, now thats one freaky halloween weapon. better than a chainsaw even!
Hmmm, now that you mention it, if I could combine it with a chainsaw...
ive started on combining one with a chainsaw. couldnt find a suitable guard and the magnets attracted the holder for the blade and that started spinning the flew a few a loooooong distance off. nearly decapitated myself to. my gf sure isnt going to hear about this :)
Nyanman7 years ago
say, to prevent the blade clogging, might a hole in the guard and a vacuum attached to it help?
mrfixitrick (author)  Nyanman7 years ago
