Don' t think this bloke did, but if you are thinking of doing so, here's why you shouldn't as this can happen to a (presumably) decent one. Click on the 'more pics' button to see better.

Ouuuchhhhhh!!

There's nothing wrong with the prop itself. If you look it's the u.j. that's failed where it connects to the diff. If he'd had a welded steel tunnel with the uprights in like a locost and cut the engine when it went he'd have had less damage.

Yes the UJ failed but still....Ouchhh!

Saw a prop on a truck fail once, at the front UJ, dropped down and dug into a road drain cover and picked the back of the truck up and chucked it about 5 feet to one side at the back!

i was told a story many years ago while i was a motorsport marshal, of a racing driver who just seemed to coast to a stop with no obvious damage but when the marshals arrived his prop had failed causing him some serious injuries.

Eeeek...
I was pretty wary of this when I built my car. I don't think the prop would escape a well made tunnel in the time it takes to push the clutch down. I also panelled in under the tunnel to stop a 'dig in' situation.

Cheers

bear in mind if it fails at the gearbox, no amount of clutch will stop it thrashing until the car stops.....

which is why in drag racing you need a catch hoop at the front and rear of the prop. usually a peice of 5 mm plate will suffice in absorbing most of this.

Locking the back wheels would stop it. I think a good handbrake is called for.

Look where the handbrake lever is in the pictures!

Would you want to put your hand nearby?
