    Porsche 917

    This story goes round and round but in the real world things were not that simple. There was a big influence of the environmetal temperature and air pressure which made longtime readings inaccurate. The big holes were detect easily but the small ones were still hard to find. mvgrijk

    Porsche 917

    As told before the engine is air cooled. This made a simple modular design possible. The 12 cylinders are all individual pieces which can be changed relatively easily. I

    Porsche 917

    OK now back to business Some other remarks I was contacted by several people to share the CAD drawings of the frame. As long one has a good story I’m willing to share because the frame is no secret at all. There was a person who like to make some calculation on the frame with the finite...

    Porsche 917

    Thanks Don. That's indeed what I was trying to say. To me it's an always returning question. To my opinion it's not the program but the man behind it. Because from most of the programs the results are interchangable and it must be because that's why thay are called 3D programs. The big...

    No I don't. I put all the parts together for a display at the annual day of a modelclub. After that I took it apart.

    With the drawing of most parts ready I then can start making the drawings needed while machining. So I start with resizing the drawings to 20% and breakdown the whole in to smaller drawings from which you can create all kind of dimensions you might wanted the use in the workshop. Print them and...

    Porsche 917

    Some remarks about the car in general. Porsche created in the late 1960 this supercar only to win le Mans thanks to an overseen gap in the regulations. If you are interested look around the internet and find an amazing story about great ideas, technics , racing skills and much more. Porsche...

    Porsche 917

    So now back to the gearbox. As said before I had no idea and no dimensions. There were no pictures. Probably the gearbox was so sturdy it wasn’t needed to open it for restoration. And maybe also because no one is interested in those internals if one can photograph the complete car. But then out...

    Porsche 917

    Now my main object, the engine was finished I did have a little problem. The next thing should be the gearbox. But it was a little big problem. I had no idea how the internals of such a gearbox look like. The small drawing I got only showing it’s principle. And also nowhere any pictures of an...

    Porsche 917

    Try using decent blueprints from one of the blueprint sites and start practicing. Maybe the first 10 times it will become **** but one day you will see the light. There are enough examples how to draw a carbody on the internet. mvgrijk

    The forum was SMCars but the most important stuff came from individuals. But you only met them by means of joining a forum and asking. This way it made me possible to get in touch with the Porsche Museum. Unfortunatley they could not help me either. Later on I will tell the story about my search...

    Porsche 917

    When starting this project I wondered where to begin. I subscribed a Car forum, a Blueprint forum, a Model car forum and even a Computer Graph forum. You can meet people and every one has his own interest and skills. One for drawing another for building models. Although I found a whole lot of...

    Porsche 917

    @Kaleb If you read my introduction in the Welcome thread than you would know that my intention is to build a as good as possible 1 to 5 model of a Porsche 917. And I don't have enough skills to make a real 12 cilinder running engine. @Metal Mickey All the images except the one with the wooden...

    @SAM in LA Most of those are no photo's but drawings from my 3D-drawing and if there is any interest in specific parts I can generate them. @T70MkIII Nice to hear I'm not the only fool. Good luck and especially in finding all the exact data of the original. @LongRat When I'm busy in my...
