It's a good example of low ground rakers on a dull chain versus untouched rakers on a dull chain. Those larger chips in the left hand have really frayed edges.

Pretty cool what you can read out of a pile of saw dust without even seeing the chains. Guy on the right is not enjoying h is cutting time at all, guy on the left is happy he's not the guy on the right as his saw is cutting good but has some fine tuning left in his chain as well as he's got the full range of chips from small to noodles. Micro tune cutters to same length, then give it to the rakers, then go make some cookies!!

Awesome, good to know these things. FYI, the pile in the left hand came from a new Oregon LGX chain with maybe 10 cuts into it. The pile in the right hand came from the same chain as it got into about 25-30 cuts.

I agree. Neither is a good example of chips from a sharp chain. The fines ones must have been painful to produce.

I have found the last 6 months to a year, that most Oregon chain needs cleaned up (gullets need cleaned out) and sharpened right out of the box.

This wood noodle crime scene investigation can be fun!I have learned that sharp and dull are relative. Just for reference.
The chain that made these chips was called dull.... because the cutters has some grime on them in the pic.
What I see here is one or two dull gullets on a very sharp chain.
I would be very satisfied with the above

Most people could gain 10-20% more usable power from their saw if they would learn to sharpen a chain correctly and take the time to do it properly.

A saw is only as good as it's chain!
The pic above is from a fairly fresh loop of RS, touched up with a file and sticky sharp. The kind of sharp that digs into your thumb when checking the edge. I was running it in soft maple that day with the ported 346/350...lots of fun.
My crime scenes will most likely be deemed "cause of death, blunt force trauma"! 
1. case, I had cut some oak log "butts" with my PS-7900:
2. case, bucked and noodled a oak log with my PS-7900 (with the chain visible in the picture):
3. case, noodled some dry pear with my PS-6400 (with the chain visible in the pictures):

Dull chain case ... after cutting a bullet in half with my PS-7900, no teeth broken or bent (force finished the job at hand but have no pictures of the chips):

I hit a 16 penny nail a while back...my chain didn't spare so well!
I must admit that these Dolmar/Oregon chisel chains are quite durable, I was impressed myself the chain looked like that after the incident.
Also, the teeth don't break or bend unless they're filed back way past the witness mark.
I like me some Oregon chisel chains.

Here is a noodle nest off a 5105 wearing a 24" bar, w Oregon 72CK sharpened w a round file. Red elm that was cut green, two years ago.
I've got a picture of a 7" noodle out of there but it won't load.
