That’s realy too bad those looked like nice models. There is a lot of stuff coming over on the container ships. I don’t know about quality, but the two steam turbines I have coming have dinky shafts so I’m goigbto replace them right away before something gets wrecked. They run abou 40 to 50k rpm just keeping a belt on might be a problem. I do have spring bels too nut indont want a flywheel turning 50 gan racing across the floor. LOL it hard to just find a shaft coupler. I had planned on making a special one but much prefer commercial one.
