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

Excellent  :praise2: You've got the line boring sorted out  :ThumbsUp: :wine1: I will have to deal with that for the next engine  :thinking:
Best regards

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

Hi everybody, the center door of the engine, with its special shape to hide the angle drive has given me the inspiration to try my very first real 3d machining with Fusion360.
In the drawings of Doug there is brass used for the doors and the gear cover is a soldered fabrication work.
My door is made by aluminium and the cover should be soldered to it too.
This aluminum solder is now since month under my bench and I would like to try it.
Here the simulation of the milling operation.
After doing a test yesterday, the real part was made today.
The final operation is done with a 3 mm ball cutter for steel, because my one for aluminum does not fit by the cutting length.
The surface is not as fine as the the surface made before one step earlier with the 4 mm ball cutter.
To be honest, I am very happy that I have learned the first steps in real 3d machining also now and new a chapter of the book (the dark side of model engineering) is open now.


Kind Regards
Achim

Nicely done  :praise2: I still have to make the first step to the dark side  ::)

Hi Roger,
to be honest I do like the dark side of model engineering very much.


In the meantime a lot of holes and threading has been made, partly also with the help of the dark side.
There has been 15 mm space for the operation to drill the holes for the end flanges.
But finally we have got it, everything was adjustable in Fusion360 CAM.

Next to do, the door hinges.


This video shows how not to operate a CNC or conventional mill.
