Tin Can Turbine Engine

Hello!

              Let me give you some insight into this project (Tin Can Turbine). I'm going to school to get an Airframe and Power Plant Cert. (Aircraft Mechanic). I stumbled across this idea on YouTube one day in class and it really got my gears turning. It's purely for fun, and I'm not even sure if I have the technical skills to get it to work.
            First of all the way a turbine engine works in layman's terms is Suck, Squeeze, Bang, Blow. The fan section sucks air in from the atmosphere, Where it is moved to a compressor section which squeezes the air into a tighter pocket of air; which makes the air hotter and more explosive. When the compressed air is pushed into the combustion chamber, it is more volatile than normal air due to the compression. When you add a fuel (jet fuel, gasoline, propane, kerosene etc...) it will ignite with the compressed air (given that there is a spark to get the fuel vapors to ignite). When the fuel/air mixture is lit the fire will continue to burn without an ignition source due to the explosive nature of the compressed air. And the gas (burnt fuel/air) is pushed out the exhaust. There are blades in the rear of the engine called turbine blades, which are connected to the front of the fan/compressor section, in some cases there are two or three turbine blades, which drive the fan, compressor sections independently. Due to the turbine blades being pushed by the exiting gasses, the engine becomes self sustaining. And through black magic, you have a jet engine!!!
             I'm going to attempt to construct a jet engine (not a motor!) out of a "tin can". I'm really not going to use a tin can, I'm actually going to use .032" thick 3" wide, and about 6" long exhaust piping made out galvanized steel. It's a lot thicker than a typical soup can, thus willing to stand up to more heat. My proposed fuel source will be propane, because it's cheap, and the I'm sure that I'm capable of controling the amount of fuel going into the engine. I'm not sure yet how many fan blades vs. turbine blades that I'm going to use. Right now I'm in the experiment phase. My blades are going to be made out steel can tops, because there is very little cutting involved, beside the actual cutting and angling the blades. and they fit perfectly into the pipe. As for the fuel delivery i'm going to use a copper pipe that is approx .042 thick and hallow. I'm going to cap the end, and wrap it around the inside of can. There will be eight holes drilled into the copper, which should give it plenty of fuel at equal pressure all the way around the can, equals same heat all around.
        As for the drive shaft, I'm not exactly sure of what to use for that. I may want to go with something hardened already, so the heat surrounding it won't melt it. (that's the hope anyways) . I'm also not sure of what sort of bearings I will use. I was thinking skate board bearing with the plastic crap around the middle taken out (so it doesn't melt and seize the bearings) and extreme high temp. white lithium grease for lube.
         This is an experiment and I guarantee myself absolutely no success. But I think it will be fun to try. Questions or comments are more than welcome. Please, if you see any problems with the design, let me KNOW!!!

For the drive shaft, an axle from the front tire of a bicycle works well
