A prototype for a CVT transmission that uses gear
Zen wisdom: No matter what happens, somebody will find a way to take it too seriously. - obviously had KB in mind when he came up with that gem
Artificial intelligence is no match for natural stupidity
Saw the second one (variable gearbox)round about a year ago, but missed the engine one before, it looks fantastic and it must be good if the French government is prepared to pour all that money into it, I need to look at it again.
Sounds a bit like Neil's experimental beam engine - think I'm slipping behind with all these new inventions, don't know how I missed that one!
Maybe I'll have to go back to looking at the ESE thread again, I stopped going there as I was spending too much time on the computer and not enough in my little foundry! which is still coming along slowly.
I don't ride bikes anymore, so I don't need to know the finer details of how to tune engines to gain 1% more power etc. etc. more interested in new technology or old foundry techniques these days - Times do change.!
Also I have read criticism about that variable gearbox, claiming that it can't work, but we'll just be patient and see if they can get it into production or at least sell it to someone who can, but you can bet that if it has any merit it'll be snapped up.
And then , there's this:-

There's some clever bugger out there that's for sure.
The plumbers D drive looks like a winner.

Arguing with an Engineer is like wrestling a pig in mud.
After a while you realise the pig is enjoying it.
This is a good description of Honda's Moto GP seamless gearbox (was looking for this when I came across the silly video above) However, Yamaha have now gone the same way and are leaving the Honda behind!

It wasn't particularly special, it was in a tea box full of brass shit I jettisoned in a rare purge.
The only things I saved from the box was a 12th scale traction engine and a stationary boiler made by my grandfather. One day I'll refurbish the traction engine and get it going. I believe the twin fuel tank pumps are fuel primer pumps from a Messerschmitt ME109. It's far from his best work, by the time he made that his eyesight was shot, he'd turn stuff a thou at a time until the fit felt right. I have vague memories of a beam engine with actual scale 1/16" hex bolts on 3/8" flanges...
Go soothingly on the grease mud, as there lurks the skid demon
I bet the pylon racing guys in America have a few clues about Bristol sleeve Valve engines by now. I think they still use machines based on the Sea Fury and I'm sure a lot of the engines used are highly modified versions of the Bristol Centaurus engine, but I have heard that many of them are using the Pratt & Whitney because of availability.
Anyone interested in this? - Honda still interested in two strokes! - How about the crank arrangement, guess that's what Neil was checking out when he made the 'beam' in the photo he sent in (on the Bucket Foundry thread)??

It's got nothing to do with high performance or competition, the crank arrangement and the movement of the piston and rod is the main thing of interest here, the rest is pretty ordinary and has most probably been done before, but if you look at the patent (there's a link to the patent there somewhere) it has everything covered and whether they ever use it or not, they've got everything sewn up and I very much doubt that keeping the patent going would be any problem for Honda!
