broken teeth on my chain.

[lurch_918]

anyone else had a origon chain shed its teeth ? I've just had a chain on its first sharpen throw 4 teeth  ripped the top plate's off . when i looked at the rest there was no under cutting from sharpening and no sign of them hitting anything . would this be a manufacturing problem ?

Metal or even a stone in whatever you're cutting? Have you cut through the wood and hit the floor? Iv'e had nails a bar length in a tree before.

Oregon chains are sold to dealers on 100ft rolls (generally, as it's cheaper to buy a roll, than pre-cut lengths) and are cut to length on site for pre-packed sale or made up to order. When a customer blames a chain for blunting quicker than expected, and is therefore 'faulty', I usually point out that their 3ft length of chain we used to make up their loop, came from a random section of 100ft roll. If the chain was 'faulty' then the remaining 97ft of chain either side of where their chain was cut from would also be 'faulty' unless of course, by sheer coincidence and really bad luck, that 3ft of chain was the ONLY bit that we happened to make their chain out of was the ONLY faulty bit of that 100ft of chain. Normally puts things into perspective and absolves the chain

Post pics of what's left, will be interesting to see.

 

Without seeing it I would think it has to have hit something, the forces from wood cutting on each tooth are fairly low. Did you feel it jump back? I've had iron fence rail rip a tooth off, and also stones 10 feet from the ground.

Iv'e had plenty of chains loose rdm  teeth never 4 at once though on a new chain.

I have the odd tooth snap off from time to time but that is when its down to the last ever sharpen ( and probably beyond what others would bother with ) I recon you must have hit something .

Keep using and sharpening, I tend to find those well used chains with small teeth cut really well so keep going until at least one falls off through being too thin. That's not what he's talking about here though.

Friend of mine brought me a chain to do on the Lidl sharpener as it was in a bad way. He was cutting a 10" trunk and hit a metal bar straight down the middle of it. He did admit to it though didn't try to blame anything else. Only a couple of teeth were completely lost so it's now a semi skip.
