    Thanks Ken, had some time to mess around on the cad thought it would be a nice touch. I've kind of stalled with this project, trying to get the rest of the parts together. Then maybe I could post a short video and explanation of the process.


    Regards,

    Greg

    Hi gv71
    Your turbine is a kamps/kj66 hybrid could you please explain the hybrid .I am building a Kamps and have just been given some kj66 drawings as I find the detail better on the kj66 drawing. I have built the front end but am not having much sucess with the metal spinning.

    Tony,

    Basically its a kamps compressor and turbine wheels, shaft and ngv. KJ parts are comb. chamber, fuel ring and outer case. I made dies instead of spinning the parts.

    Hi Greg, I would really like to get more info from you on how you milled the turbine wheel - I am building a smaller model (Dia 48mm) turbine and would like to know how did you mille the blade profile?

Probably not this one but the next one I build (in the works) which is a little smaller it has a 54 mm dia. turbine wheel where this one is around 66 mm will be going into an RC jet. Here are sompics of the turbine wheel and of a diffuser that I was milling out with my homemade mill.
