Re: 5/32 or 7/32 file

Strange thing happened to me the other day.  I decided to cut awhile on the many treetops in my timber from  logging last fall, and grabbed the wrong file for my saw which has a H30 .325 pitch chain.  Instead of a 3/16, I had got a 7/32.  So I decided to touch it up anyway.  Could not believe the difference it made on the sharpness! Much better.  The chain is better than half gone as well.  Anybody had a similar experience?

Sounds like you didn't hold the correct file at the right height, mainly filing into the gullet. The too large file likely was forced into a more correct positon by the bottom of the gullet. With that file there won't be enough hook on the cutter, so it is far from ideal, even if it by accident was an improvement in this case.

You should use the correct file, and hold it high enough that 20% of the diameter is over the top plate of the cutter.
