Beautiful!

Everything is perfect Achim.

Very good detailing    Not long now

KVOM (Kirk ?), Carl, Roger and Vince, thank you very much for still watching my long term Snow build and of course thanks for your compliments too.


Shop time is rare at the moment and life has given some special tasks to solve, what distracts me a bit from the Snow build.
Never the less, I have found some time to shorten the tank rack by 25 mm. The upper possible fuel level should be same hight like the needle valve in the carburettor now.
Hopefully it is  at the right position now.

I understand how life just keeps coming at you and taking up all your shop time.
That looks beautiful Achim!  Your work on this engine is simply amazing!

Hi Kim, thanks for watching.


The water outlet tubes are nearly made now.
Some flanges made on the lathe, a small fixture for drilling all first and than the later contour milling on the CNC mill.
Another fixture to keep everything in place for the soft soldering.

Very nice, as always!

Those look great Achim. You should be getting close now!!

Achim, I haven't gazed at this thread for a while now. That is some seeeeeeriously high quality workmanship you have done there. ...OZ

Hi Achim

Good to see progress; the water piping is a very nice piece of work.

Masterful work Achim and still following you........

Chris, Bill, Oz, Dave and Don thanks for still following along. It is a good to know that you are still interested and following this build log. And of course thanks for the compliment.

The very last missing big part is the exhaust pipe now.
But to make it in the same way like the intake manifold I do need the exhaust valve cages mounted.
To mount them I have to make first the last missing studs.
To fix the studs and the valve cages, the cylinder units have to be removed from the  sub base.
If the cylinder units are removed, the sealing between the lower hidden bolts and the water jackets has to be made.
There are still no lip seals at the cylinder ends around the piston rods.
And do I still have a good electrical ground connection from the ignition system to the plugs ?
There are some paper gaskets and  anodised aluminium now between.
But Bill, yes in relationship to what  has been made up to this point , I am close now.

Achim, I had a little time left today and have looked in your build log off the Snow engine.
Still follow your build and amazed every time I look to your progress.
It’s a superb job.

Hi Tjark, thanks for checking and the friendly comments.


I have had some time to go ahead with the coating of the last made parts.
First the water outlet or top tubes have been coated.
On tube was a bit to hot in the oven, so the soldering came loose and a flange against the tube  was not aligned any more.
For me a signal to check and to control the temperature more accurate..
To fix it again, the tube was mounted at the soldering fixture again heated up to 210 C° and carefully adjusted into the right position by a 3 mm bolt, screwed into the outlet side.
The powder coating at this temperature is so soft and elastic, that is has followed the 10° to 15° turning without any problem.
Next coating object was the carburettor, everything disassembled and plugged.
In a RC shop I have found a nice air filter, which was easy to modify for this purpose.
On the oven thermometer is still 170 C° visible, a good temperature for my soft soldered parts without any damaging risk for my 220 C° soft soldering wire.
The high tec carb with air filter on it, is in my opinion now optical wise much better integrated into the over all picture of the Snow model engine.

Looking better and better Achim. Great pictures also.
