Only two days until Speed Weekend and the jet kick is ready to go, so I spent last night in the workshop on the JU-02 engine.
I made the shaft tunnel casting deliberately long until I knew the exact measurements of the engine, after assembling the axial bearing and fitting the turbine shaft I could measure how much I needed to remove. On the pic I have also started to make an alignment ring so I won´t have to use dowels.
With that done I made a stainless seat for the turbine shaft piston ring seal, I will weld it to the rear NGV wall later.
Arboring the hole for the ring seat.
Here the seat is pushed in place, I have some work left to do on the NGV wall before I can weld it.
The turbine shaft fitted in the seat to test the fit.
I reached some kind of mile stone 23:30 last night when I could assemble the diffusor plate and shaft tunnel with the rotor in place!
Cheers!
