Don't listen to him Dave. Just another retired guy with too much time on his hands  :ROFL:

It's good that you are getting time back in the shop after that nasty accident last year. Each day you will be able to do a little more than the day before.

Cheers :cheers: :cheers:

Been exactly a year since the surgery to put it all back together!....

Im trying boss!!!  Im trying!     The bearings were a very satisfying job..the first one just slipped together perfectly!....The second, just a touch with a file and it was done.    I'll do bearing shells like that next time for sure....it was really pretty easy...just required some careful work with the holding fixtures...but the F1 was up to it.

Way to go steamer! You seem to be on a good roll now. Firing on all cylinders as they say.  Haha!

If  you look at the last picture, the core had some taper in it... I'll mill that wall down, but it's at an angle, so I'll need to trig that out and work out the offset and drop for the ball end mill to clean it out

the top side too, which is straight up and down, is a bit close, so I'll trim that too

I'm sure the sump pan is close, but I know it has some meat on it.

The 917 engine will be bar stock....just sayin

Slope side cleared out..     offsets like George does it.  Are not that hard.    If you think about it a minute    68 degree slope.  Which amounts to a 2.5 rise to run    so out .02 and then down 0.05.  Cut   repeat.    Worked nice.

Its not that bad Bill.  move the Y back 0.020, and raise the knee a full turn.....cut from X = 0 to X =0.687 and return

Repeat
You get into a rhythm, and it's not bad at all.  Pick opportune dimensions....1 turn of the knee is 0.050 for instance...
