If I find it you are more than welcome to have it!

Thank you for your kind offer but I will pass on it. It's a bit big for my requirements and machinery.

I won't be attempting the quill drive and I don't even know what a "bomb" is! Maybe you can educate me.

In fact, the gear train isn't strictly scale, more "inspired by". My model will be running on compressed air and will be two stroke so there is no reduction between shaft and cam. Here's a drawing.

As you can see, this is a simplified version designed to resemble the original. This is with mod 0.5 gears, if I can cut mods 0.33 or 0.25 gears it would be more realistic.

It is good to hear from somebody who has worked on such an iconic engine and it's derivatives. I have never even seen one in the flesh.

Cheers

Steve
