If they react anything like a band saw as soon as the blade breaks it falls away . Ive had bandsaw blades break on me and they just rattled around the body of the saw.I had a chains saw blade jumps off the bar last week Apart from damaging the blade it caused no problem |

If they react anything like a band saw as soon as the blade breaks it falls away Band saws are friction driven with a low mass blade - so the moment it snaps there is no drive - and since it has little mass will stop very quickly - especially if mid cut. A chain is sprocket driven, and has more mass - so it will stay engaged with the sprocket as long as there is load on the tension side. Hence it may still get driven for a while until it disengages from the sprocket. .

(Also modern saws have chain catchers near the return side of the sprocket to catch and snag a wayward chain). -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

I saw a bar drop off a saw in use and watched the chain shoot forward (luckily) about 3m. ;-( Cheers, T i m |
