Chain sharpening difference?

[2manyrocks]

How used are your sharpening files? The files in my Pferd were getting dull. Just changed them out for new ones, and the results are so much bettter.

I’ll update this thread. To recap my MS250 chain always seems sharper than my MS261. I used the MS261 a couple of days ago and it was cutting so-so and then it started curving as it cut. My normal sharpening technique is about 2 passes per tooth. I did 5 this time, it cut great then.

My conclusion is I use the 261 on larger wood that also in this case was a little dirty. It also has a larger fuel tank so it cuts longer on a tank. I just need to sharpen it more often when I notice it cutting poorly. Not exactly earth shattering news to anyone but I initially thought one saw was cutting better for some other reason. Sometimes I also notice it will be throwing good chips but some saw dust mixed in. I assume that just means some of the teeth are dull.

Cutting a curve can be caused by an unevenly sharpened chain, a bent bar, or spread guide rails. You should not be waiting till the saw is "cutting poorly" to sharpen it. Your description of the saw sometimes throwing chips and sometimes sawdust is often indicative of spread or worn guide rails. Did you try swapping the bars?

I would like to add uneven raker depth in proportion to the cutting teeth.

I sharpen my chain only when I need too, when I feel like it's starting to loose its edge then I will do it but during the winter when I don't hit anything I can go days without sharping it.

Hand sharping is a superior sharping then girder if you can be consistent with hand sharping. The locals with forestry feller with the chainsaw style bars much ratter hand filing their chain then grinding it as it last longer.

Got a picture of the cutters?

I think they’re good. I bought a package of new ones a few years ago.

I’ll get one. I appreciate everyone’s answers. Self criticism can be tough. My initial reaction I’m sharpening the chain correctly but I wouldn’t be posting here if that was 100% true.

Good point many folks use their files way too long, you can see and feel it, one can replace them after as little as 10 filing and as much as 30.

Then somebody doesn't know how to set up the grinder properly.

There's always a certain level of heat generated with a grinder, grinder can create micro fractures and dose create a rounder edge where hand filling there is none of these.
