Well it is time for a photo update, the photo update was late November '13 , in that time I have been building the better part of +/- 2700 parts into small assemblies , now here is a photo of that effort that has gone into it in the last 7 to 8 months, now I can start building the cylinder heads and do the timing of the engine at last after 2 years of thinking how I am going to get it right.
When I am finished assembling the 11 heads I will post again some photos. R |

update time....
After 10 days I have now finally completed the building of all the cylinder heads In the photos below is the 12 cylinders head complete and also the heads in there correct spot on the engine, now the real fun is going to start in that of getting the timing correct and figures crossed working, if it does not work then it will remain a static model of the engine, but lets see how it goes..... What I will do is post more pictures after the timing work is done |

A little bit of sad news, I have glued 10 of the 12 heads in place and what I have found is that the engines crank is not going to be able to take the torque required to have the engine turn over. I am still going to do the engine timing so that it is correct.*
Even if I made the the crank bearing shafts thicker the crank shells would have failed next.* |

I have now got all 12 heads in place, I have had a good look to see why the engine does not want to turn over and the problem is the gearing in that with me having to make the gaps and holes of the gears more on the open side of the tolerence scale which is fine for a free moving model, but when a load is added those open tolerences do impact the movment of the model and the gears then start to jam and that is the main reason for the model not working and also I have tried a few different valve springs and I also had springs made and it also is problem at the end of the day.
Really is sad, but when I do the next engine design with the desmo valve setup of the V-twin engine it should turn over.... |

Ouch, broken cranks are no fun...at least it wasn't at speed. This may be almost impossible to overcome without a sealed, coated (Teflon) paper or some type of lubrication. The desmodromic setup should help some. Is this going to be a Ducati type engine?
