Pictures from your chain sharpening.

Could you take a photo of the files please.

 

 

God I'm sad.....

That looks great to me.

I am learning to sharpen square ground & it is not easy maintaining a clean angle from the top corner of the cutter.

 

It's a complete pain to maintain. Where I was working in Oregon, the only thing the local shop had was full skip square filed. Impossible to sharpen in the field, so you brought several loops with you. In clean Douglas Fir, they last a good while. In anything other than clean, or in hard wood like oak, it would go dull alarmingly fast. But in Douglas Fir, which is one of the main woods it was designed to cut, it was stunningly fast.

 

Here is my bone stock, aside from a muffler mod, 372xp in an Oregon big leaf maple(about like a bog ash in density) with half spent square filed full skip on a 28" bar:

When Im chain sharpening if I look up I usually see rolling downland with woods dotted around .

I've had a go at sharpening square ground - and it is almost impossible free hand!

 

 

Plus the files cost a small fortune compared to a round file.

 

 

ATOP - are now looking at developing a chain that comes between round ground chain and square ground. You still sharpen with a different file but it is around 100% easier than conventional sqaure ground chain.

This is the only way I've found works. Er.. "works"... I use this technique on round chain when I hit stones(only I use a round file...). It works well for taking a lot of metal off.

Its certainly not as easy as using a round fill but the limited experience i have with it, if you tighten the chain (to help stop lateral movement) and have the bar help firmly, with vise (in the workshop) or in a shallow cut into a stump and file out from the tooth same as a round file it works real good. The double bevel file works really well.Everyday is a school day.
