Will you quit doing that !!!! Ouch

 

[Hedgerow]

But this phone takes good pics!

Gotta use it for something..?

 

[Redfin]

I did some more "practicing" tonight. I wasnt concerned with finishing a chain just really focusing on how changing the file effected the cutter. I dont have paint on my phone so ill try describe my question with Matts pic.
See where the file starts at the corner of the tooth and ends at the curve on the underside corner. How critical or what changes as that point moves up or down on the corner? This angle is reletive to how far you are getting into the tie strap below that cutter.

That angle changes as you change the underside of the top plate.

If all the cutters look like that,it should ne a super smooth cutting saw.

This is the chain porn thread.
Don't tell Moobs.
He thinks we're self moderating.

Hey Matt, you still got that wicked little mini-mac?

Lol..
No..
I sold the silly thing..
Got a 7-10 Mac to replace it...
Starts like crap, but runs like a banshee after it gets going!

More angle toward back = faster more agressive..
More angle down toward tie strap = longer lasting.

Just think how the little beaver wood have cut with some of that new chisel picco square filed.
Have you or anyone tried square filing picco yet?

It's a bit of a pain.

I was kinda thinkin it might be but had only seen pictures of it since my dealer didn't stock it.
I know the Stihl .325 RS has a lot more room for the file than the Oregon .325LPX, and was hoping that would be the
case with their low profile.
See you had to rub the tie strap a little which i do a lot on the .325LPX.

Just make more room.

That looks wickedly sharp

I recently picked up a couple loops of Stihl 63PS chain to run on my ported ms260.

I want to try a square file one of the chains.
I've had good luck with 3/8 and .325 square.

My question is this, should I maybe run the chain through my round grinder first to rough set the top plate angle before I try filing it? Any tips or suggestions are also welcomed

I have double bevel files and the triangular files. I'll see which file fits bests.

I'd just hit the tie straps with a dremel like in my picture above. Your really gonna nail them if your doing working angles.

Any thoughts about depth gauge heights?
Maybe .020-.025? IDK

I've got a 16" bar and a 7T sprocket.

This chain will be run on my drf255 ported ms260.
Basically I'm wanting to make a gtg chain.

 

[concretegrazer]

Then definitely don't hit it with a grinder. IMO

Start high on the gauges say .015-.017 for softwood. You can always lower them. Tunneling has been shown to help as well.

 

[Canadian farm boy]

Awesome. Thanks. I'll hopefully play around with the chain tomorrow. I'll be sure to post some pictures when I do.
