That looks really great Achim.

When you mentioned the weather there, you reminded me of Munich.  I guess I will miss the Christmas markets and as my wife told me this week, no Stollen this year for Christmas.

Hi Roger, there are a lot of steps necessary for the hopefully first pops and bangs.
First to do, is to connect cylinder number two, another challange.

Kim, Vince, Don thanks for giving friendly comments. Motion is one thing, compression and all the other IC engine related issues an other. We will see what is comming next.
Kind Regards

Looking good Achim, one step at a time and you will get there. The motion looks really nice thus far!!

Bill, Dave thanks for watching and the friendly comments. Shop time is again very rare at the moment. I have got it managed to make some more studs from SS and fitted the second cylinder to the running in program. It is running with nearly 60 rpm and after 15 minutes my poor little Chinese e-motor started some sweating. I have to interrupt the run than for 15 minutes for the next stint. The video are showing only some seconds, the time to archive the the result have been hours of adjustment.

Coming along nicely  :ThumbsUp:  :ThumbsUp: That motor should be ok up to 70°C.
Best regards

Hi Roger, may be you are right, but the power loss at 50° C stopped my motion already.
If I see the Brian Rupnow set up, may be a reason to think generally about my installation.

Hi Achim,

The increasing resistance of the windings as the temperature increases will reduce the power if the supply voltage is constant. Can you find a couple more volts?
Best regards

Hi Roger,  I am using an old small Sunbattery lead accumulator and an old 12 Volt car charger, so no real chance to increase the voltage.

Hi Roger, I took your advice and have made a new investment at Conrad Electronic this morning.
More voltage, longer running time up to the temp limit.
