My computer and the mill has been busy during the afternoon also.
3 of the 5 door frames are also done already.

That's a lot of machining  :ThumbsUp:  :ThumbsUp: Are you saving the swarf to sell?   :stir:

Hi Roger,
I would say still not enough swarf to get  it sold.




In our national forum we do have a long term thread about Fusion360.
For this thread I have made 2 videos which does show the simulation and also the real machining of one door frame of this engine build.
May be somebody is interested to see it, I have tried to keep the machining video short by a lot of cuts and focusing of only a part of each operation.
It starts with the measurement of the Z zero of the brass plate and also shows the tool changes.
No music, the original sound is also available.


First the simulation created by the CAM module of Fusion360


And second the machining.






Attached also some pictures of the current status of the BME crank case.
In one of the holes I have lost a 1,5mm drill bit,  so I had the remove it by grinding this area, that is not a big issue because of a later final machining at this part of the crank case will  done.

Hi Roger the purpose of these 2 mm holes are more simple.
They are only for the fixation of the entire building for the soldering process.
But at this place with the shown mishap, not necessary, nothing to fix there.

Hi Don, good to know that you are still watching the European activities.
Enjoy the brass design as long as you can, but finally it will disappear under a coat of paint or powder coating, sorry for that.
Kind Regards

Hi everybody, a new experiment was done last weekend.
Milling a 197 x 98 x 10 mm aluminum plate without the usual fixture to the mill table.
The plate was fixed by some tape to a 20 mm victim plate ( is this the correct English expression ?)

A complete CAM program (G-Code) was created by Fusion360 for the whole job.
At the end I was happy about the result, even when it has been interrupted by a broken 3 mm flat end mill.
Kind Regards
Achim

I think the terminology you were looking for was 'sacrificial plate' because it gets tool marks on it so it's sacrificed.

There was a bigger adventure to get the plate solved from the sacrificial plate.
I try to describe the phrase "a pain in the a....." here in a polite way.

That was clearly my fault, because I have used to much tape and to much surface.
I had to use a torch and than the heat of nearly 90 C in the plate and a piece of hard wood and a hammer did the job.
Next to do, some milled holes at the other side of the plate and the small door on side of the crank case was also made in meantime.

Some more doors are made.
Here the collection of frames and doors so far.


Chris, thanks for watching.
