Gauge 1 steam turbine rotors and input/exhaust inserts

thingiverse

A set of .stl files as components for the steam turbine designed by Werner Jeggli, Designed for precision lost wax bronze casting with the wax positives individually 3D printed. Details of the turbines Werner has built are in his many articles and soon will be in a book that is being created. Werner comments "The only jewellery caster I found so far who is willing and able to do these castings is Kauselmann/Pforzheim/D https://kauselmann.com/. Their representative, Mr. Fessler cautions that such fine castings are prone to casting faults and may require some fiddling to clear the bores. Shapeways/USA https://www.shapeways.com/ has resumed their lost wax casting service but they refuse to do the nozzle castings (too difficult). There might be other outfits for sourcing these items, closer to home. Give it a try
