Yes, keeping the tooth tight and straight is the problem.
The machine sharpening is really a HUGE difference from hand sharpening. The mechanical grinders, 1) take too much material off the tooth, 2) don't really maintain the tooth radius the way the tooth was designed because as the grinding stone wears down, the radius it grinds changes, 3) grinding stones produce heat which takes the hardness out of the tooth, especially as the tooth becomes smaller and there's less material to dissipate heat, 4) mechanical grinding cannot take into account the 2 different types of teeth; chisel, & semi-chisel and the different ways they should be sharpened, 5) the length of the tooth HAS to be taken into account in relation to all the other teeth in the chain. If one is damaged to the point where sharpening will make it substantially shorter than all the others, then it should be left alone until the other teeth reach its' length, and finally, 6) people who are using chainsaws should know the basics of what they are doing, both to be safe as well as proficient, and this includes the maintenance of their machines. To me, it's like driving a car without being able to put gas in it.
You're right in that people need to know when to stop. Chainsaw chains should never be used until they're so dull they're burning their way thru the wood. Even in debris like you have near you right now, I would be touching up my chain as soon as I noticed the teeth getting a little residue sticking to the top of them. 1 or 2 strokes with a file will return the chain to where it should be. I can do this on my 30" bar in about a minute and I keep a file in my pocket with my wedges.

Hey Eric, saw where Ohio was in the news again
Woman Robs Her Own Tax Preparer With a Curling Iron
By Stephanie Rabiner, Esq. on February 1, 2012 4:58 AM | No TrackBacks
If there's one thing you can learn from Sonia Watson, it's that you shouldn't rob your tax preparer. Especially if you plan to use a curling iron.
Police in Toledo, Ohio are currently searching for Watson and her son after such an incident. The pair went to a local Liberty Tax Service where they encountered a woman who had recently prepared Watson's taxes.
Fumbling, they then carried out the curling iron robbery.
At first, the mother and son duo covered their faces. But when they realized customers were inside, WNWO-TV reports they removed their masks. When the customers left, they re-covered their faces.
Sonia Watson then wielded a curling iron -- wrapped in a towel -- and threatened to shoot the tax preparer if she did not give her money. The tax preparer refused.
The robber responded with a curling iron smack, but the victim fought back. She hit Sonia Watson with a plastic soda bottle, reports WUPW-TV.
A witness then stepped in and hit Watson's son with a chair. The duo then fled with $280.
Perhaps they were unhappy with their refund amount?
Mother and son are still on the run, but when caught, Watson will likely be charged with robbery and assault with a deadly weapon.
Yes, a curling iron is a deadly weapon -- even when it isn't turned on. Those things are tough and can cause quite a bit of physical damage.
As for Sonia Watson's son Antonio, his age is still unclear. If young, he may face lesser charges for his involvement in the curling iron robbery.

What color was the towel? I might not take a pink towel very serious. But if it was a tiger striped pattern I would be more concerned.

I agree about the heat issue but again, if you stop before it gets really dull, you can bench grind it without damage. You just have to be willing to be patient when you grind it. I sharpen full chisel at 25* and semi at 30*. What else is different? You do have to occasionally touch the grinding rock with a dressing bar to reshape it. As to a short or damaged tooth in the chain, you just have to skip it as you would with a hand sharpening.
As far as differences in the 2 types of chain goes, when filing the semi-chisel, the file needs to be kept at more of a downward angle coming off the tooth on the off-side. Mechanical grinding doesn't take this into account on EITHER style of chain because it's just grinding straight down towards the base of the tooth. Running a file straight across the tooth, 90 degrees to the bar doesn't do much better than a grinder except you maintain temper. Both styles need a slight downward angle of the file as its' drawn thru the tooth. As far as raker filing goes, I don't file rakers until the tooth is at least 1/2 worn down, and at that point I put a straight edge along the top of the teeth and a feeler gauge between a raker and the straight edge, then try to come as close as I can in making them all the same tolerance. Rakers become bent, only slightly, but bent none-the-less, and this affects height. If you file them at the same time as sharpening the tooth, they all get filed down the same amount even tho some of them might be at the wrong height, so they remain wrong. The feeler gauge compensates for this and I only do that about twice in the course of the chains' life. All this may sound trivial, but combines, it makes a big difference both in performance and longevity.
I'm glad you know to skip teeth that are shorter, but most places you take a chain to be sharpened either don't know or don't care. They just all get ground regardless. Around here they're getting $7 a chain to sharpen. I still don't know a LOT of people here, but there are a few that pay me $10 a chain because they've found the benefits of hand sharpening for 10 as opposed to the grinding for 7. They drop them off at night and pick them up in the morning. They'll either swap out or touch up their teeth during the day and bring them back to me at night again.

ANY grinding of the teeth adds heat and takes away temper, even if it's done correctly. You wouldn't think it makes a difference, but it does. The 'tree people' that used to park here at the farm would tell me they could get another hour from their chains when I hand sharpened them the night before for them as opposed to the ones they'd switch on from the grinder later in the day.

I know a couple people who take pink VERY seriously - an obsession almost.
Morning all. Off to see what it's going to take to put a culvert in.
