bar disintegrated?

[treeman82]

I was in the Stockbridge office today and brought with me the CA/FACE write up from the Commercial Tree Care forum. One of the kids in the office told me that it did not phase him because he had seen a guy get his eye deflated. He told me that a guy was cutting with a Husky chain saw a while back and the sprocket on the nose of the saw disintegrated and a piece of metal went into the guy's eye and REALLY messed it up. Apparently the chain stayed on the saw, and there were no obvious signs of damage. This is just what I heard, and am bringing it to you guys to ask if there is any validity to this story. Have any of you guys heard of this happening before?

A small piece of metal in your eye can be there for several days before it gets real bad, and will actually rust while in your eye if it is iron or steel. Eye protection is a must.

A small piece of metal in your eye can be there for several days before it gets real bad,

I can vouch for that. Last year I got a piece of a vitrified tool wheel and some small steel chips in my eye. The chipes where embedded in my eye and every time I blinked it would scratch my cornia. After being a tough guy for two days I couldnt take it any more. I ended up haveing a doc pic the particle out with a small prob and having to wear a pirate patch for a month.

Hey Treeman, that kid thinks seeing an eye deflated is more impressive than "total body fragmentation"? He must not have gotten the point of that phrase. I have not heard of the event you described with the sprocket tip. Russ

I would imagine that a tip failure would occure almost instantly upon starting if somone unknowingly put a 3/8 chain on a bar with a .325 tip ect...

I started this thread to ask simply if anybody has ever heard of a tip sprocket disintegrating? If I remember correctly, this kid told me that the chain could still spin on the bar no problem. I do know that he said the guy had the saw going at high idle for a while when this happened.

Its not that common but i have had that happen before, mostly with windsor tips, but my boss had an oregon tip do it yesterday, wish i had a camera, cause they look pretty wicked like that.

The Windsor tip on my 111 hasn't let go, but did go all stiff and lumpy. Probably not bad for a 20 year old bar, but I'll have to replace the tip before I use it again.

I've seen it happen with HOMELITE bars. Usually caused by the operator trying to extend use of a streached chain climbing the drive sprocket...Something has to break..The chain if so badly worn or the tip sprocket. I've even seen drive sprockets break a weld from the same reason.
HOWEVER... With the chain going away from the eye, I can not imagine your gruesome tale being real. When the sprocket breaks it has been in large chunks and the chain drags, wedging into the slot.
