How to square file

[Battle Cross 2]

I tried another chain last night. Going to try it tomorrow and see how it compares to my first one. Someone said this one was to pointy so I tried to fix that with the new one. May have gone to far the other direction.

Gonna be grabby but if you've got the power it should cut like crazy.

That chains for my 3700 so tons of power may be a problem. Guess I'll leave the rakers high and see how it goes.

It may just be the picture but the rakers look low to me already, but I like an aggressive chain.

 

[Xr650jkallen]

Well maybe they ain't that low. This is the chain on my 28" .

Can't test chains if the saw won't go . Hopefully parts from the shed of misfit toys will have it going tomorrow.

With the cutters that short and long gullet the rakers in your post at the top of this page the rakers might not be as low as perceived. If the gullet is close to 7/16" an entry angle of 6.5 degrees for the cutter would need a raker set at around 49 thou. That's a bit aggressive but not too bad. You might be right there. 3700 has the torque to handle.

This is the chain with the short cutters. It's a little grabby in oak but would probably be fine in softer wood. This whole square fileing thing is new to me so I'm just figuring it out as I go.

Seems to be cutting through that oak pretty quick!

 

[RI Chevy]

Seems OK...
Only way to figure it out...

More worried about durability with those pointy cutters or breaking cutters off if it hit a knot or something with those short cutters.

 

[Xr650jkallen]

That's my kind of grabby.

3700 maple. The not pointy chain. Short fluffy chips
Maybe bring the rakers down a hair?

 

[RI Chevy]

Rakers down a couple swipes will give you bigger chips.
I'd go 1 swipe at a time and try another cut. If you go too much, takes a while to get it back...

I’d use a progressive raker gauge.

Longer chips are harder to clear as well. Gullet seems to make a difference in chip length and clearing them out of the cut.

I dont know that I'm looking for longer chips. Just seems to me it would cut better with the rakers a hair lower. The cutters probably aren't perfect either as this is only the second chain I've tried to convert.

Smaller bite = higher in cut chain speed, bigger bite = PH gets pulled down more hence reducing in cut chain speed

Both scenarios can result in a fast bucking cut taking the chain feeds well on it's own, balance between both will be the optimal condition.

Just my observation.

Just an update. I heard back from the guy from Vallorbe files. They got some in.
