Chain talk

[mdavlee]

Chips are cut off and curl up in between the raker and cutter usually. The ones that don't get caught by another one behind it.

I square filed some semi chisel once, it was really weird looking when done. I was not sure it would even cut but it did & quite well. No pointy triangular corner as semi curves around but as stupid as this chain looked it cut really well.

You wouldn't have a picture of it would you? Was the side plate closer to 45 degrees rather than 60 degrees which you would find on a top plate angle of 30 degrees?

I'll have to dig it out 2morrow Terry. What was funny is that the unique line that goes up the inside of the cutter with square chain cannot meet at a point due to the nature of semi but it was there. The top plate & side plate resembled square just not where they meet. I'll post a pic in the morn.

I used what I have learnt here and took to that Stihl chain I linked a picture of a few pages back.

Leveled out the raker front edge to help push chips, cleaned up the gullet and sharpened the factory grind with a 13/64th file.

Its now much sharper than out of the box.
I bumped it with my hand lightly, just brushed over it reaching over the bar for a flat file and it slit me open like a razor.

You may consider a piece of paper to test the sharpness with ,over your finger .

That cutter is a horrible design..
But should work on hard stuff..

What dont you like Matt? Big difference Im seeing is the little height difference between the nose and tail.

I hate short cutters. Though in hard wood, you can get away with a shorter cutter. But being .404, I would assume it would be used on a big powerhead in larger fresher wood, so why would they want to hamstring themselves right out the gate? Maybe for sheer durability.

That chain fly's on the 346. Rakers about .015. Has been rather durable also.

Any problems with too much drag thinning the raker tips ?

Nope. They're smooth to the touch. Rounded.
