Big bore liner, first 3D CAD model

I have drawn this up for a friend in France, but have got to translate it to 2D for the liner company, looks vaguely familiar doesn’t it. :)


but this is better skunkworks. I have a 44mm DCNF carburettor lying around, so I thought it might make a useful addition to the standard 38mm Zenith NDIX, but it won’t fit on a standard inlet manifold. Time for a CAD session, and rustle up another 3D model.


As you can see the big bore project is gaining momentum.
