Broken-Wrist proof ignition crank.

An ignition crank with an over-running/roller-clutch (with backfire protection provision) so that once the engine fires up there would be no chance of your wrist being broken!

I may be wrong but I think he is asking about something like a ratchet wrench setup that will not spin the handle around once the engine kicks over. The product you linked to is not intended for starting the engine, I believe.

Item 74 is intended for engine starting. It has a curved slot where the pin in the crankshaft engages. When the engine starts, and starts spinning, the pin "catches up" to the speed of the crank, and as that speed is exceeded, the pin pushes itself out of the slot and disengages the crank.

It probably isn't foolproof, but the fact is, there's no way to make something like that foolproof. I personally think a ratchet system would be overengineering. The main thing to remember for safe hand-cranking is to avoid wrapping your thumb around the crank--just use the four fingers, in parallel, against the palm.

Bingo! (If the damn Brit's can do it on the 1975 850 Mk3 Norton Commando) then by golly we/someone can do it in 2009!

PS - I am not saying the Brit's used a hand crank on the 1975 Mk3 but they did incorporate an over-running clutch with backfire protection device in the newly designed electric starter...but of course, the Prestolite 2-brush starter wasn't capable of starting a cold Mk3, it had been previously used to auto-start tractor-trailer refridgeration units that were much less demanding than the Commando motor. (Pa Norton must have got a deal on the 2-brush starter units surplus from a trailer refridgeration company!)
