Stock as in round ground or as in squared up?

Lgx=round.
The steps were taken from top to bottom.
The 346 was run with its own classic 3-cube chain.
No holds barred..
Just cause I wanted to know.

Stoned = stoned outside of cutters..
Still factory sharpened round cutters.

Looks like I need to start paying more attention to my chains! Pretty cool data.

Stock LGX is round. I think it reads like this:

562xp:
Stock LGX round.
Stock LGX round, that is stone ground (by grinder)
Stock LGX round, that is stone ground (by grinder) with gullet material removed
Stock LGX round, that is stone ground (by grinder) with gullet material removed and cutter tails nipped
Stock LGX round, that is stone ground (by grinder) with gullet material removed and cutter tails nipped, and square filed (by the master)----2.6 seconds with the 562

Same chain with 346xp: 2.15 seconds

Matt is just showing the progression of the performance increase with each modification of the chain. And, he is bragging a little about his mildly ported 346. The performance increase by removing of some of the gullet caught him off guard.

Matt, correct me if I am wrong on any of this

wow! impressive.
now, for those of us not so tuned in to chainology, me, please provide visual clues regarding outside the cutters, gullet material removed and cutter tails nipped.
thanks much

I edited my post. Matt will provide pics. Yes, it is impressive, very time consuming, and not practical for everyday use. These chains are for one thing and one thing only....racin'

I have always thought race chains were goofy looking. Now I understand why.

So not the same chain on both saws?

No. couldn't find a bar that would work on the 346.

I'd like to think it was the chain, but that saw is just a freak.

Race chain theory makes my head hurt.

Yes, it is! Chain probably helped a little...

346 chain.

That won't last long cutting hedge. Just saying.

 

[workshop]

Yep. Me too.

Didn't mean to sound sarcastic on the subject.
Just so many numbers and angles and I have no idea what they do.
To be honest, my best chains are brand new ones.
