Hi Dave, Per, Kim, Vince and Kerrin,
good to know that you all are still following my learning curve.
Thanks for watching.


Next to do, to clean the shop a bit, lots of aluminum swarf all over and to finish the the top plate.
I am doing some more thinking about the hard soldering job already.
Kind Regards
Achim

Looking good  :praise2: Those doors will certainly put your CNC gasket cutting skills to good use  :)
Best regards

Hi Roger,
I have had some thought about gaskets already, but to be honest, there will be nothing real to seal against.
Optical wise, may be a 0,1 mm gasket in the split line will be nice, but that will be a job for the plotter than, some long time in future.
Kind Regards
Achim

Hi everybody,
some conventional milling  again.
The top plate, with its 3░ taper each side, is now finished also .
Now is only the reinforcement of the lower frame missing.

Don and Chris, thank you.


During the last weekend I have done the first soldering attempt of the crank case.
The result is not perfect so far, in my eyes, but also not so bad at all.
A lot of heat was necessary to get it done.
My used silver solder has had a melting temperature between 590░C and 640░C.
To get some kind of basic heat, a cheap Chinese outdoor cocker was my selected tool to help.
Unfortunately these guys in Asia didn┤t know anything about the coming missuses, so I have to report that the integrated Piezo element for the lightening was not able to  resit the heat during the process.


Kind Regards
Achim

After cooling down and some cleaning with citrus acid, I have detected three areas which are not in the way I would like to have it.
So I have to attack these a second time.

Good result so far, one thing I would do differently is take it all outside! At least open the window right there, dont want to gas yourself with the combustion gasses, or melt/set fire to the cupboards above even. Even with fire brick, a lot of heat goes through them and also up to the ceiling, and carbon monoxide is nothing to mess with. For larger parts, it does take quite a bit more heat from a larger capacity torch, you need to get the parts up to temperature to melt the solder before the flux burns off. If you are going to be doing larger parts, well worth the investment in a larger torch, I love the Sievert ones with changeable tips that attach to the propane tank from an outdoor grill. And 'outdoor' is a key term...

Hi Chris, this corner is prepared for some  soldering jobs. The big window , nearly 2 square meter is 1 meter beside.
The fire extingusher is under the table, right side at the picture and water left side 50 cm.
