Math is hard.
I'm going to go get more caffeine and try to read this one again .....
...And so is English apparently. I think you are being nice. Sorry to all. That was a pretty rough post. I only had about 15 Corrections as I just edited it.
Concentrating and writing can be hard at best of times for me. It certainty doesn't help when I'm short on time along with someone hanging over me saying "We got to get going". Doing math in my head as I go is generally the easy part for me.
OK..the math was just a trick.
100 cutters would give you 50 per side so therefore. (In theory) it would be a straight cut. Lol J/k
Ok..since I was rushed I probably didn't have enough coffee myself
I can make it a lot more simple.
Let's just pick an odd # representing the amount of cutters on your chain.
We will use 25, 25:1 ratio.
Match the cutter tally to the diameter of the log; each tooth should cut 1".
So if your chain had 25 cutter the side with 13 cutters should in theory cut an inch more.
The worst case may be a very short bars with skip chain. I don't believe one tooth alone has the pull and one tooth ends up 'searching' to even it out. A combination of too loose of a chain and slow cutting speeds is when it will make the difference I believe.
That's when I have trouble; often when I am forced to slow chain speed down due to kick backs from the flare when I cut the back cut to my low side on large diameters cedars mainly. Have you noticed a poor cutting chain may only cut at a slow speed? What people may not give thought to and that is the fact that the chain is pulled giving it an inward force (centrepical force) Many people believe a good raker gauge can make a chain cut even with a significant amount of shorter teeth behind long teeth because they are gauged the same. That's simply not true due to it inward force just mentioned. Again a few teeth are OK but its got its limitation. Someone that grinds will not take all their teeth down because of one or two smashed teeth. The mishap will likley be corrected after a a bunch of grinds and the chain cutters will stay even to the end. They will flip the bar dailey as well use a raker gauge and it will cut straight to the end.
