You are correct John. Take a look here

Hi TW, thanks for the link. That setup is not something I like to try to explain without pictures. I think there has been a model boat kit version of the Voith Schneider drive.

Thanks for the pics, very interesting. I have a limited but keen interest in insect flight too.

Hi Tony,

Thanks for a super piece of research, write it up and I'll send you your PhD! I saved your effort as a PDF, will check if it worked later.

Seriously though that really does make a great start to the New Year. Many of the old publications have such great "Food for Thought". A colleague was doing something on transistors and I found in my heap of scavenged paperwork a copy of Mechanix Illustrated (or something similar) referring to a patent from around 1939, I think. It described in detail a three electrode solid state device and he was "over the moon" to include the reference.

I've always loved mechanisms (hate the Science Museum London - of today). As a ten yr old I built a paddle boat using an old wind up gramaphone motor to drive the paddles. I avoided the mechanism associated with the paddles by having them barely touch the water. Sixty years plus and I still haven't faced up to the work of making that relatively simple mechanism but I love it.

It must be an age thing, I really enjoy Heath Robinson, Emmett and even the American whose name I can never remember. I'm also collecting Roy L Clough designs. I guess it's rather like electrical equipment where you can more or less see what happens unlike solid state gear where it has to be taken more or less on faith. I did find at my college that the electronics staffroom had a far greater proportion of believers than the engineering staffroom.

A belated Happy New Year to all.
