Dull Chain Thread...

[Brewz]

Brewz were you able to test that strange file job

No not yet
The saw is ready to go, and when I get a spare couple hours on a cool day ( it's summer down under) I will do a comparison test

Could be a week or 2 but I will do it, I have kept the chain

Which is worse....chain on backwards....or a dull one? lol

I sharpened the back of the cutter as a joke on my buddies chain as he put it on backwards a few times.

The old crosscut saws cut in both directions - 'bout time the powered saws caught up . . . .

Looks like half the chain is backwards. One half the chain faces one way the other half faces the other way

i bet it cuts good..... haha

Yup. Bought it like that. Got half way home and noticed.

Wish you would have kept that chain

Was probably pieced together at the shop, late in the day . . . .

It's even worse when they put a twist in the loop.

I have the dodgy filed chain I posted a while back bolted onto an 066 and will give it a run tomorrow for a laugh.

Will see if I can get one of my kids to video it

 

[jakethesnake]

Sounds like fun if you get a video I'll watch

 

[Wolverine]

for a laugh.

Should be a good work out!

 

[Brewz]

Haha...... well the chain cut about as good it would if it was on backwards.

Please excuse the rich tune, I had started it cold and let it idle for a minute or so and it needed to burn off a bit of oil when I cranked the revs. Running 32:1

My wife didnt know I was testing a blunt chain and as you can hear, she was surprised.

My 12 year old daughter did all the video work for the day.

 

[Brewz]

We put the chain into my fathers electric grinder and took about 0.100 off the teeth to remove the top bevel.
I tried to file down the rakers but my flat file is blunt and it wouldn't do the job.
I would take a guess at .010 to .015 rakers in this video after I tried to take off what I could.

Some of the rakers had never been touched and the chain is now only 1 or 2 sharpenings from the bin. I wonder if someone tried to file the top bevel edge on to get it to cut, not understanding what the rakers do?

 

[Brewz]

The timber is seasoned rock hard eucalyptus.
We dont have pine, or any softwood to make the saw look fast

 

[Brewz]

For comparison, here is my red light with a razor sharp chain in the same timber.
The tune is not great in this video as its the first time I have run it and I am still working it out.

I did a bit of work on the tune later on and worked most of the bog out of it.

 

[Philbert]

Looks like you made a difference!

(So, you are saying that sharpening helps?)

I spent last weekend cutting tornado blowdowns at my father in law's place. All of the neighbors and friends showed up and not a single one had a remotely sharp chain on their chainsaw. I wound up filing chains for most of them so they could get some work done. I showed up with an experimental square filed loop of Oregon BPX, which was fun for the first tank of fuel. I can't see well enough to resharpen it in the field though, so it had to go back in the box after that.
