Hi and welcome, in this instructable we will go through how i made a turbo jet. This is in minimal detail if you would like more detail and photos please visit my website: http://thejetman.webs.com/

Before we begin as you probably know Propane and LPG are flammable gases so be extremely careful and turbo jets can back fire or explode in certain cases. I am not liable if you or any person or your property are hurt or damaged if you try to build this.
Now for the fun stuff.

To make something like this you would need a well stocked tool kit which would include:
a drill to make things easier a drill press
an angle grinder
a cut off saw
of course a hammer
a few brains
and maybe a few more things.
The first thing i did was make an oil pump. To make this i used some rectangle shaped pipe, iron plates, hose, welding rods and an oil pump off a Subaru Ute. I welded the pipe to one of the plates, then drilled a hole for the oil pump to fit into( would have been easier to use an oxy). Next I had to put in the drive shaft to drive the oil pump (make sure the shaft is straight). I then had to seal the tubing using pvc pipe cement.
I did not use any of the math or other mumbo jumbo to get the right size combustion i just did some research and followed my gut .I now needed to find a turbo charger, so I went to ebay and found a good deal $200 including postage for a 200HP Hitachi turbo. Later i found out it leaked water into the oil supply.
To make the combustion chamber i used some pipe which was about 12cm in diameter
and some smaller pipe for the flame tube which was about 7cm in diameter. The flame tube required about 80 holes drilled in it, this is when a drill press and some sharp drill bits come in handy. The holes closest to the top are smaller, then they should increase in size as you get closer to the output end. please refer to the photos of how it goes together.
Now the final thing to do is hook up the turbo to the combustion chamber, find a spark generator eg an electric fence and an ignition coil, hook the oil pump up to the turbo, and the water supply if needed as well. Then connect the gas if you are sure their are no leaks.
To start it i used an angle grinder with the head taken off, which did not work very well so i suggest getting a high pressure air supply or a leaf blower to start it.
My jet did not start very easy because the bearings were screwed but when i did get it running it sounded like a real jet it was absolutely amazing to watch.
Remember visit my site for more details on how to make it http://thejetman.webs.com/ and later i will upload my latest spark generator.
28/8/10 Tried to start it with an air compressor but failed so I have decided to get a gmc 26cc leaf blower to start it up so you guys can watch a video.

Here are some new photos.
Does anyone think it would be worth making a jet kart comments please.
