i did a little build thread over on cnczone.com under the turbine section, but it was just some pics posted every now and then. i'm thinking about building another one and filming every part i make, speeding it up and putting it on YT.
depending on what you want to do with the turbine tels you what you need to buy. take the NGV. you can make it out of .5mm SS and spot/tig it all together, but if you run the turbine for more than a minute or so it will warp and you'll have to make another one. i intend to fly mine so i went with the cast NGV. you will have to buy the turbine wheel, compressor fan and the bearings. you can make the preload spring, but at Â£3 from Wren its not worth it. like the front and rear nut, they both have a left hand 6mm thread. the tap to do this was Â£36, but again you can get both from wren for 12 odd quid.
i also got a combustion chamber from wren for the same reason. the inconel tube was Â£40, to make a spot welder out of a microwave Â£50 and material for the tooling to make the end caps Â£20. they sold me a C/C for Â£120. since then i have found out how to make a spot welder for free. if i knew that then i would of made it my self.
do you have lathes and mills??

i have one that a fellow forum member set me to see if i could fix. if you want a nice and easy pulse jet to build look up Japanese valveless pulse jets.
