Chain grinding and filing thread

[Chainsaw Jim]

Yikes. Scary Jim. Not much there. Lol
But I bet it's fast

You think it's at risk for breaking? There's hardly been anything taken from the drivers or straps... or rivets. Lol

Here's a few pics of the chain that's been on my 024.View attachment 129977 View attachment 129975 View attachment 129976 View attachment 129978

Holy cow!

Do You take a new loop and grind it down that far or do You utilize a worn work loop?

I've noticed that loops worn down to triangular teeth are scary fast.
The only issue is that they create a very narrow kerf.
How do You counteract that on a race chain?

Oregon 73/72 LGX will endure extremely worn down teeth.
Considering the loops integrity, I have yet to snap a 3/8" chain other than the one TriLink that broke on me in 12 years.

JR shares some really nice pics of his work on his google pages.
Again, these are his not mine. Said the last one was very fast.

Some nice sharpening for sure.

Hey Jim, do racers ever run beaks on their chain?

Where do you guys get the 6 sided files for square chain and whats a good price? I would like to try.
Do saw dealers carry it?

Not much cutter left. They will be breaking off soon.

I prefer starting with a brand new chain. I'm not filing it all the way back, I'm taking the backside off to keep a taller tooth. If the kerf becomes an issue then the rivets get flattened and a narrow kerf bar is recommended.

You'll notice quite a few feint beaks to get just enough hook to feed.

Most shops keeping square ground chisel in stock will also stock one of the files. The 6 sided file works well, I prefer the double bevel flat file. Many folks have trouble with one or the other.

A smaller cutter then I typically run for falling all square is done on an older pro sharp.

Damn I sure hope not, I'm expecting to get at least 6 cords of dead standing locust cut before the next sharpening.
