1909 MERCEDES

AERO ENGINE BUILD

Part 12+1 by Steve Gosling

...continued from part 12.


Putting the crank together.























Trying to keep it all true using the angle plate which has a convenient slot to dodge the big end.

Half a crank in the lathe to check the alignment. It was a couple of thou out but a good push soon brought it into line.
Then the other end.
Another alignment check and adjustment.
The final push
The moment of truth. As expected, it was not perfect but 0.010" out. I took a slightly brutal approach and jut put it back in the press to give it a push!
Actually, this worked although it did take me three hours to get it good enough. It is now within 0.001" eccentric which I think I can live with.
Just skimmed the bearings to length and it is all beginning to look promising.
Machine the sump to match.
A crank case with crankshaft which rotates!
