Hey guys, I've got a few saw chains that were used with an extremely worn bar. So worn in fact that it wouldn't hold oil very well and cut crooked as a dog's hind leg. The chains are Sthil .325 X .063" that currently measure as thin as .059". I'm guessing that they're still good to run, but thought I should ask first.
Saw chain drive tooth condemnation wear limit?

I don't know. I've usually trashed combos like that, although i have never measured them. I've never put a chain from a really worn out bar on a good one. When i buy a new bar, i usually replace the chains.
If the chain wobbles side to side, will it wear the new bar faster?
I don't know it if makes any difference but i flip my bar over every year.

I, like spasm said, might discard that chain and get a new bar.
Those drive links under the chain will wear excessively when used on a crooked bar.

Buy a new bar and chains and learn how to sharpen them. Never cut with a dull chain and you will file the cutters off before the chain and bar wear out. You might need to replace the spur/rim sprocket also.

It's my fault for not adding that these chains were purchased a few years ago and haven't seen a lot of use. That's why the question. I[d hate to throw an otherwise good saw chain away.
Is .004"-.005" that big of a deal?

In fact, I did just replace the rim- but thanks for the reminder.

As long as the bar isn't bellied out too bad, you can re-square the rails. You'll have to check that the drive groove is deep enough to let the guide on the chain run in it completely. Squaring them is pretty easy and can be done on a belt sander or you can buy a special file just for that, you also need to deburr the sides of the rails as well.

You'll also need to check the nose sprocket for wear. I usually replace the drive sprocket or rim with the chain or when it has a groove worn in it from the chain drivers.
