Raker profile

[Lightning Performance]

I've had similar thoughts to this, same basic concept. I've thought about filling the back side of the raker with my flat file. I gave up on trying it because there is a good amount of material that needs to be removed until you're into the ramp of the raker and can start marking it shorter.

I'm trying it tomorrow with a much better grinder I borrowed.
I have almost beat chains in 3/8 72dl to waste with high drags and ramps still untouched at the front leading edge. Flat filed semi and chisel. Every one hit something hard and unforgiving.

The digital angle finder will tell me where I'm at.

Do some before and after video cuts Ken...
See if there is any improvement in cut times...

Just comparing cutter profiles of new Husqvarna C85 chain and Oregon 72LGX.

I was always of the belief that Oregon made Husqvarna chain. Are you sure the Husky chain isn't the new EXL?

No EXL and C85 are 2 different chains. C85 is wholey Husqvarna made.
Click back and forth on the arrows on above attachment and see how the 2 rock back and forth in profile.

I did some vids a bit ago using same saw, same stick of wood, Husqvarna C chain, Oregon EXL chain and some other new boxed chains.
The Hooskie chain was the fastest by a lot!
It does have a very big hook.
My only concern is being able to maintain that same factory hook...

I'd love to have a loop of the C85 in my hands. I heard it cuts narrower too??? That grind profile is almost square chisel. But the Oregon LGX is not much different, just a smaller gullet.
Seen special square files do that in Europe for the Stihl Timbersports. Can't remember the file company.

Husqvarna C83 chain.

Oregon EXL chain

Same saw, bar, and test piece of wood.

My other comparison was Stihl square box chain. A bit different raker style from Stihl.

The Husqvarna C85 chain was definitely "doctored" from the factory to help promote the 572XP when it was introduced.

I think it will be tough to maintain that factory box hook. I have not seen any tutorial showing how to properly file that new cutter.

Did you notice any difference in cut speed after filing the C85 with a 7/32 file?

This is the angle I like on my work chain what the older LGX had.

They used to. A few years back Husqvarna went on their own.

I have a strong hunch a 3/16" round file could come close to getting the C85's out of the box hook.

I normally take the gullet way out to clear chip better on 3/8" LGX. Stihl chain I don't feel the need to do that.

Jeff, I got no real wood here to test work chain. Buncha sassy sticks and lil crappy firewood in that blue trailer. These chains are going to be tested on the mill. Ten and fifteen degrees. I can do some work chain but not in this maple load I got yesterday. Twenty to thirty inch wood to mill for shelving my hut later this year and bench tops with no bugs in them.

I'll go get fresh red oak for consistent testing of this depth gauge idea on work chains. Next week maybe.

I only made the 3 cuts in the video with that chain. LOL
I haven't filed it yet. [emoji4]

I'm in a similar predicament, in the middle of a 320 sq ft slab patio and no time to cut wood.
