Just a suggestion

You are interested in creating a jet engine without stators ( to simplify the project) and thereby use your CNC skills.
Let me suggest a slightly different project if I may.
There are a number of different used/surplus free turbine helicopter engines on the market that have the potential of being converted to jet engines.
If you merely remove the free turbine, you end up with tremendous vorticity out the exhaust since the turbine nozzle for the free turbine is usually part of the prior turbine stage.
What these free turbines need is a properly designed nozzle that redirects the flow axially or redesign of the final turbine stage to create axial flow.
The question then becomes would the project be too big for your equipment.
Just a thought.
