Lynx II, hull # 4225

Tony, I'd suggest that your ratchet bolt is more for show than use. It is far more likely to have the crankhandle start spinning with the engine after it has started, than one of the originals.
I have seen this. I was in the Army on exercise in the J in Malaysia. I started a 150 Cu Ft. fridge (Onan 2 cylinder diesel as I recall) In this case the handle had a sprung loaded wedge. These handles are short but heavy cast steel with a wooden handle. "Anyhoo" it spun with the engine (straight up to high idle) and then flew off. It hit a man in the side of the head quite hard, knocking him to the ground. I honestly expected it to kill him, but after a few minutes he seemed o.k. The guy was a Singaporean bus driver, working for the N.Z. Army. I never saw him again, but always think of this incident, whenever a crankhandle is involved. I think the slot cut of your bolt leaves a bit to be desired. Just sayin. Btw, I have one of them, small hex, better ratchet?
