Square filing chains

Your doing fine, IMO you'll have better results with the bevel file as you stated.

Its just like anything else........its a learning curve.

Your chain will cut better than the stock RSL.....Under the top plate was almost blunt before.

 

You guys keep going I may have to do a little more work on my chains.

 

$hits gettin' real boys, l o l.

 

Thanks SF !!
I can now use eithor the 3 corner or the double bevel just fine ( I think) .......
First pic is before being wiped off, next is after, third is just a close up. These right cutters are from the 3 corner, the left cutters are easier for me to file with the double bevel, but I can easily keep the corner with both sides and both files. Now its just keeping the top plate on a single plane, as I am finding that when I use the 3 corner, I tend to round off the top plate just a smidgeon............... I know; practice - practice - practice !!!

 

I would take those any day

Nice work

 

It shure is !!!

I know I aint gunna finish anywhere close to the front dozen, but I can definately state that my cut times will be significantly quicker thanks to this thread. I was avoiding square filing like the plague for the past few years ...... there are no square grinders near me, but with the help from you experts, I can now keep the corner and get a decent cutter with the file. A few more strokes on the few right cutters that have the slightly rounded cut on the top plate and this is going into some wood. I am going to have to run the stock RSL first so I can get a feel for what square cuts like when new off the roll ................ then this chain is getting put on. Since I am going to use the stock one I was saving for the chain race, I will just spin up a few more in the next week or two so the competition has a brand new and untouched one for baseline.

I am going to try to clip the rear cutters of this chain after I see how she cuts, and I also plan on reducing its weight a little................ wish me luck fellas, its all new to me !!


Getting back to work chains, is there anything else that should/could be done to the pics I posted that will decrease cut times without sacrificing chain longevity/durability ?

 

Thank You SF !!
I have to run and get a towel, I am getting misty eyed now !!

 

To gain cut speed you'll give up some durability. There's no way around that. How long you want it to last will decide how fast you can cut. I'm happy with a 2-3 tank chain.

 

Read em and weep...

 

Or not...

 

Low rakers, forward lean, no tooth left some side beak...
Will it ever cut????

 

Yes.....or you would of never done all the work!

 

Thinking out loud hear about side plate angles.....correct me if I'm wrong.

Its obvious forward lean has sharper angles.

Back lean would probably hold up longer.

If the side plate is perpendicular with the tie strap wouldn't it be the most efficient?

When I imagine it cutting I picture the cutter not rocking back off the bar rail, pulling through the wood better

 

They rock like a wave through the wood and down the bar as it cuts. With forward lean when it rocks back it still has a tiny bit of lean into what it's cutting.

 

What I'm trying to get at is

Do you think with zero lean wouldn't that help prevent the cutter from rocking back and be more effiecent?

 

That chain is kind of extreme...
What I did to it yesterday, was an attempt to fix a couple of its woe's..
The low rakers and forward lean makes it stupid aggressive, so I changed the underside angle and filed it back a ways... It's not smooth like a straight profiled cutter, but with enough power, it eats an 8" cottonwood can't 3" on contact.. Just made it very sharp, and put it on a strong 4cube, and will hope for the best...

 

I'd sure like to believe that bro...
But never underestimate my ability to spend a lot of time on something that turns out to be a dud...
