There was a plan for a Turbo Generator in ME, it was back in the 1950s/60s somewhere (I think). One of those projects on the roundtuit list. My thought is to make a bigger one for powering a generator for my traction engine. I'm already pondering the possibilities of a very high speed milling/drilling spindle for the BCA. I'm sure that Turbines are under-used, at least by non-dentists. I hope this information can be useful to someone looking for a very easy turbine to build. The testing of this turbine is given in my thread for testing model engines. This is a very small turbine with a 7/8' rotor that has been run with a very small boiler and a small airbrush compressor. The more advanced design is for a Terry turbine rotor that can replace the tangential turbine rotor and use all the remaining parts. I call my existing turbine a tangential turbine since I have not found a common name given for the open pocket tangential flow turbines. The drawings for these turbines are also shown in the gallery. The photos of the turbine assembled and the major parts are in my album. To get the ball rolling, I'll share the information I have on my model steam turbine and a more advanced design I may build. I started this thread to create a place where we could share information about model turbines.
