I just bought a used oregan 511a grinder. with 4 stones...5/32 3/16 1/8 and a flat stone. How can i determine the right size for a chain i have no information on. ie the bar or box it came in? Some of the stones line up pretty well? smity
Thanks Philbert for the information, it will be a great help. The problem i still have is how to determin what chain iam working with. I need to know the size of the chain before i can use the charts you sent me. I read something about measureing the distance betwee three rivits and divide in half and thats the file size. This has not worked for me so i must be doing something wrong.Oregon 511A manual attached.

Philbert, i wish i could be a chain nerd>lol Thank you for the wonderfull information. I printed it out and tried to study to make sense out of what i think i know. I was under the usumption that there just 4 or 5 different files to sharpen with?? but oregon and stihl try to make it more dificut.I thought you could measure the chain pitch and divide in half and that would give you a file size??? but a .404 pitch in half would be a 13/32 " file and .325 would be a 21/64"file????? i would asume you would get the file as close as you could.What iam getting to belive is that i could sharpen all my friends and neighbors chaines with the 3 wheel i have.Each manufacturer has a different system for numbering their chains. If you only use one brand of chain, you can look for that number stamped somewhere on the chain (if it has not worn off). If you work on many different brands of chain, you will have to reference a few sources (usually on their websites). Here are a few (below). Also check the Oregon Maintenance and Safety Manual:

The other option is to buy a simple chain gauge tool for a few dollars; they are fast and easy. I use all of these methods, since I work on different chains. And because I am a chain nerd.

^ That’s not correct. ^I thought you could measure the chain pitch and divide in half and that would give you a file size???
Thanks Philbert .. i will print and save.Some more charts (!)
Most people run 1 or 2 makes / model of chain, so it is not complicated to keep up the right file / grinding wheel size.
The 'em' chain might be Husqvarna, and the '36' might mean 3/8 low profile pitch, 0.050 gauge.
The STIHL chains are probably 3/8" pitch, since they call their 3/8 low profile chain 'Picco' ('P').
