I'm confused on grinding wheel sizes to use on different chains. For example, I have both 3/8 Lo Pro and .325x.050 chains. Its apparent to me that an 1/8" grind is appropriate for the Lo Pro, but its not as clear for the other. I spoke to Baileys today and ordered some of their chain and they indicated all should be ground with 1/8", but some of the literature says to use 3/16" on the .325. One of my chains is 23RS .325" and it sure looks like 3/16" is correct......the other is the H30 Husky chain (Oregon somthing I'm sure) and it appears to be somewhere in the middle. I used 3/16" on it and it cuts super but several places say to use 1/8". I reckon it affects the hook and side plate angle......are there any rules of thumb, or is one faster/more durable than the other?
