Last weekend I decided to work on the main bearings. There are no bronze bearing shells. I wanted to change that and make split bearing shells out of phosphor bronze.
The existing crankshaft is 12mm in diameter, not 12.7mm, which would be equivalent to 1/2 inch. I drilled out the main bearings to 15.5 mm to get enough space for the bronze shells.
Before I milled the small base for one of the bearings to exactly the same height as the aluminum base. It was also too wide and was machined exactly according to the blueprint.
The bronze round pieces were divided and soldered again to a piece of brass with soft solder. And then it continued on the lathe.

In the end everything went well.

 The build is clearly going well Michael, so similar to building a Stuart Major.  :)

Thanks to everyone for the good words.
Yes Andy, just a little smaller.

There is now a groove on the crankshaft for the flywheel, gears and also for the crank. This groove didn't exist yet.
There is still a lot to do.

Michael
