I am using a 5/32 file in a flat guide like this

http://www.mowersupermarket.co.uk/product/323-73/OregonChainsawSharpenerandGuide16265%20http://mowersupermarket.co.uk/oregon-chainsaw-sharpener-and-guide-16265

In this pic there seems to be a file shaped area below the top edge,  is this what you mean by leaving the cutting edge blunt ??



I will post a pic of the file position tomorrow as it's too late now.  I have noticed that I am cutting lob sided,  which fits with me maybe sharpening better one side than the other.  Will try to get a better pic of the sharpened edge too. 

Many thanks for the help,  will continue tomorrow lol

It is the top plate edge, and the upper part of the side plate edge that do the cutting.

The file guide you referenced is supposed to hold the file at the right height (1/5 above the top plate), with the guide resting on the top plate and top of the depth gauge.  But the photos you posted do not appear to show you filing in that area.

Sometimes it is hard to tell from photos.  Maybe this (attached) helps?

try pulling up on the file as you are filing to make sure you are sharpening the top/cutting edge.

I eventually decided I was getting a better file job as I started pulling instead of pushing.

Hi all,

I looked at how the file was sitting on the teeth and this is how it is



I gave it another sharpen and this was the result.  I tried to pull the file up onto the underside of the tooth.



How do they look??

I have no bigger logs to cut up yet so that will have to wait but they feel sharper.  One thing about using the file guide,  I was resting it on the top of the tooth and the top of the hook thing opposite the cutting face,  if you get what I mean,  is this ok or should the file guide only touch the top of the tooth?

Thanks,

Graham

Looks like you're getting the hang of it! Try filing without the guide on a junk chain and learn to file without the guide.

Looks like you are getting your money's worth from that chain!

Yes - you are using it correctly.  That is what holds the file at the correct height.  You just need to focus on keeping it level, and at a consistent angle while filing.

Looks like you should also check your depth gauges ('rakers').  They need to be filed down periodically so that the cutting edges bite off the right amount of wood.  I use the Oregon gauge with the space in the middle, which works good with the low-kickback chain you are using.  Round over the front edges of the depth gauges after filing, so that they have the same profile as when new.

Those guides are basically useless, as they don't let you see what you are doing with the file. If you have too use a guide, use a Husky roller guide, but make sure you get the 3/8" low profile variant.

The best is to file freehand, while looking closely at what you are doing. Use a file handle with an angle indicator, that will get the angle close enough (the exact angle isn't critical, but the higth of the file is).

To the OP - please remember that the advice here is worth what you pay for it, and clearly, often contradictory, as contributors share their opinions.  Choose what makes sense to you, try it, and see what works for you.

Someday I hope to make a trip to Norway and see what his chains actually look like, and cut like, in person . . . .

(P.S. - Nikko, I don't think that the Swedish roller guides will work with the chain shown in the photographs.)
