With a slight touch of fever I made some progress on the compressor section after work today, to do the final grinding of the compressor clearance I assembled the core of the engine.
Here I am about to torque down the compressor nut, I didn´t have a socket that fitted the star shaped pattern on the nut so I had to improvise a bit. I´ll get a proper socket and use the T-handle later.
With that done I started countersinking the stainless cover screws.
Some jobs are both easier to do and leaves a better result when done by hand, this was such a job. It would have taken forever to properly align all 15 holes in the mill since the compressor cover is too big to fit the rotary table oriented this way.
Finished! I´ll leave the cast surface of the cover as it is, it looks much better than a mirror polish that I probably would scratch up terribly.
Then I spent an hour doing the final fitting of the compressor wheel, with scribing paint it is easy to see where the blades rub the housing.
The JU-02 is really starting to look mean now, perhaps difficult to see on a picture but it sure makes the JU-01 look small.
Cheers!
