Another chainsaw question

[anthonyk]

After getting a lot of much appreciated advice on how to sharpen my chainsaw chains, I finally opted to have an "expert" do them. Costs about 4 bucks per chain, and they've got the right looking power tool. BUT.... after I picked them up and started using them, the saw seems to pull to the left in a curve.
In fact, it'll darn near cut a backwards "C" in the log.
Is this due to incorrect sharpening? All 3 chains do it.

thanks, Anthony

Yes That's exactly what happens when I try doing it myself.

Well, that is what happens when someone sharpens the chain with a grinder that isn't 'dead on' when setting the angles for the two directions of the teeth. I have found most operating a chain grinder don't really want to pay attention to how to do it right. That is, set it, and just touch each tooth the first time around, then take just a very small bit more. They want to hit it hard, once, flip it, and do it once on the other side. If the angle is off only a minute bit, the chain will cut crooked.

I had to re-do the last chain by hand, after taking it to a shop because I hit a stone and knocked a lot of edge off many teeth. But, the angle was real blunt and it wouldn't cut wood when I got the chain back. I looked under a magnifying 10x lens and could see it was poorly ground. Had to file it several times to get it back to cutting again.

Pretty disappointing, to say the least. /forums/images/graemlins/frown.gif

Measure the length of a right hand cutter compared to a left hand one. My guess is they are ground at two different lengths. They should both be equal in length and if they aren't your chains will need to be resharpened.

Not all " Chain Sharpener's are Created Equal " /forums/images/graemlins/ooo.gif

Just as oneself they also go through a learning curve.

He either forgot to sharpen the teeth on one side, or he sharpened them differently. Somehow half of your teeth are getting more work done.

I use a good ol' saw shop and he has pride in his work. No lawnmowers, generators, or weed eaters. The place works in chainsaws and would be humiliated to send out a chain that cut crooked.

The problem with experts is that they use HD grinders and take a bunch of meat off the chain quickly. You can do a better job yourself, it just takes a bit of time and a tiny bit of skill. Too bad they ruined your new chains /forums/images/graemlins/crazy.gif Not unusual from what I've found.....

Just be sure to take the chain back to the 'grinder' man, and have him make it right. Can't cut wood with a bad chain.

I'd like to hear what he says.

Thats why I bought a grinder & sharpen my own chains.I think I paid approx. 200.00 for my grinder . I think harbor frieght has one for about 50.00.
