Brian, those teeth look great! Is that done on a Grinder?

I started using the double bevel file (instead of 3 square/triangle) and like it better, but I still touch the straps on the opposite side.

Is the Oregon Chain different than the Stihl in that respect?

 

[Mastermind]

I hit the strap there too Mike. Most people I've seen hand file do.

If you'd back off on the sideplate angle..it doesn't do anything anyway lol

I do all my chain on a grinder Mike ,i can dress the wheel different than a file will produce ,only time i hand file is if i am demoing for someone to teach them something ,if you run a file through my ground chain it takes about 10 swipes to reshape the cutter to the file ,i do not drag race i just want my saw to cut if i lean into it and not take all day ,was running a stock 441 last might with round and square ,the wood was frozen so it went kind of slow so i was not able to try out chain angles like i wanted

If you try to get a 30 degree top plate the strap gets nicked easier than if you go to like a 20 like i have been testing ,is harder to get the sideplate this way with a file though

That 3 square file was really beating up the top straps on the opposite side. It is less with the double bevel file.

I'm learning here. Even us primates can be taught.

That side plate angle does alot on square:

A rear sloped side cutter will not self feed well and will require a shorter raker to pull and feed, reducing the cutters life

A more forward leaning side cutter will help self feeding and can have a taller raker, increasing the cutters life

 

[MustangMike]

Ditto what Mopar says, the corner & side plate are IMO the most important with square. The goofy file diminishes both, but makes it harder to screw up the side plate.

The side plate angle Mopar is talking about depends on the angles you are using, and the angle (tilt) you hold the file, that is where square gets tricky.

Hence, the sarcastic little purple dude looking up at the previous post. And the lol. Lol

The winning Ps chain had a side plate maybe .060" wide in the chain build off.

 

[MustangMike]

??? I don't follow?

 

[beaglebriar]

I file round. It probably looks like hell to some of the better filers but it gets the job done. I never even heard of square filing until I hit the forums.

The fastest chain on the 63 PS in the work and race category looked like round filed and had a very short side plate. The side plate doesn't have to be tall. Just .050-.080" is all that is touching the wood any way. The raker depth is pretty much all the side plate that gets to work. Cut down into a cookie and kill the saw at WOT with pressure on it. Break the cookie off and look at what the chips, cutters, and rakers are doing like that. A lot more stuff will make sense then. Not every cutter will bite the whole time.

I'm gonna try this sometime. Just to see.

 

[MustangMike]

Thanks, I got ya now. The thickness of the side plate cutter height.

 

[mdavlee]

You can have a 1/8" wide side plate but it's not doing anything after the thickness of the chip. Just less room for chips. The longer ones are harder to clear though.
