I always consider the soldering a success after it cleans up and looks good.  And your's looks great!

Per, Dave Art, Don and Kim thanks for the friendly comments.

The computer was busy again and most of the top is done.
I do love these "adaptive cleaning" in Fusion360 CAM.
Also the deburing, made by the CNC mill, is more and more one of my favorites.

Achim,

This is a really complex fabrication and you are making it look easy - keep it up!

Thanks Simon.


Today was the day to make the crankcase bearing places.
I have never used a long boring bar before, so it was time to make some.
Two bars where made, one the conventional way for a 6 mm round HSS bit and one for a Microbore Cartridge, as Jo, Jason and Mike have used/purchased it.
The rough-machining was done with the conventional type.
When the hole was big enough for the Microbore cartridge, I have swapped to the other boring bar and made some experiments to get familiar with it.
Nearly finished with the operation 41,26 mm was measured in the hole, 41,28 mm was the target.
So I felt encouraged to try the 0,02 mm adjustment, which was successful.
Kind Regards
Achim

Dave, Kim, Don and Roger, thanks for taking the time to follow my build.


Today some minor progress at the crank case.
The holes in the plates, previously used for the soldering fixation, are closed now and also the space for the lower bevel gears are made now.
Kind Regards
Achim
