The great thing about having a rivet spinner

[user 122190]

I screwed up yesterday, and the chain came off. My fault, no doubt about it.

Several drivers were damaged and the chain no longer would move in the bars grooves. So I got out the dremel and stated removing metal in an attempt to save the relatively new chain. After 30 or so minutes, I said screw this and tossed the chain in the garbage. Then I thought Hold On. That's a $30 chain. Today I will go thru it and remove the 10 or 12 damaged drivers and reconnect the chain. It will be a 91, 84, or a 72 driver chain and work on my other bars on my other saws. This will be the 3rd or 4th time I will be using the spinner. I feel it has already paid for itself. The other option would be to take the remaining good chain to a shop and have them reconnect the chain. Nearest shop to me is 50 miles away. No Thanks!

Tis a great thing, running the same chain specs on all my saws and bars (i.e. 3/8, 0.050 -- everything is cross compatible).

You might try a hammer and anvil to pound down some of the bent up metal.

Then use the dremel to reshape the drive tang. It should take a lot less grinding.

Now wearing a 28" B&C. Newly recovered chain was dragging in some places, but loose enough after some oil to rotate under the saws power. Now it is perfect.

I've been there.

I'm not suggesting it but with a chain that won't turn due to burrs I've hit full throttle while simultaneously striking the bottom of the chain on the bar the way it should be turning against a stump.

What I find interesting is that a 32" Chain cost less then a 28 incher. Oregon 72EXJs is what I have stock piled and considered a good value in chain costs vs performance.

I've done similar, I just loosen the chain way up, pin the throttle for a bit, tighten it down and keep cutting. If I'm close to home or a file I'll fix it properly, but for a light derail in the middle of the woods this method works fine.
