This sounds really interesting - good luck with it and let us know how you get on. If you're making compressor discs then presumably the stator discs would be fairly easy to make too, if you have to?
Did you ever see - I think it was a French guy - made a working scale model of a racing Ferrari - complete with fully working flat 12 engine! Absolutely amazing. The engine poppet valves were about the size of matchsticks, and it sounded like a real Ferrari when it was going.
Incredible!
