What's wrong with me? My chain? My saw? See this dust flying fine as flour?

Kind of like more than 2 genders???

Another full chisel is circled in blue, so someone may have spliced in the semis in the middle.

Might be a illusion. The OP has 5 to 6 years of chainsaw experience, so his in person view of the chain would address such an obvious irregularity. Right?

Great catch Harley...didnt notice that. What a weird combo!

No I think it's an illusion. No chisel in this chain. I always buy chisel but this came on the saw.

No illusion. Someone just spliced in some different cutters/sections.

 

[Philbert]

Pretty basic stuff here.

'Most' of the cutters appear to be semi-chisel, so they will never have a point at the corner. Not sure about the apparent mixed cutters on the chain (?).

But if you can see light reflecting from any cutter edges, they are not sharp.

The depth gauges appear to be filed funny, and inconsistently. It is the top of the depth gauge that matters, and they should be rounded over to match a new, factory profile. Rounding them over towards the gullet does not do anything.

If the depth gauges are too high, you will be taking small bites, and could end up with more powder.

Even if the chain is correctly sharpened, you may end up with powder, if the wood you are cutting is extremely hard and dry. But that chain could use some attention.

One hell of an illusion for the top plate to form a sharp right angle on one tooth in the photo and not the one in front of it?

Seriously, sharpen the chain and show us your starting point. Sharp chains stand out, whereas dull chains are difficult to tell from a picture. When I look at someones working chain, I see if it will prick my finger tip. Looking don't tell a whole lot.

Finger your what?????

 

[ATpro]

I agree, but if it is an illusion the angle is all wrong on that mystery tooth!

Ok... I was second guessing after looking at the picture. I made two laps around that chain and ALL links are the same. There are only semi chisel (Stihl) and no RS chisel teeth in this loop. I'm sure of it.

If you do not understand what Harley an Philbert are saying, just trash it and start with a new chain. Unless you are gunny.

Not the same chain?

 

[HarleyT]

Do you think all of these chisels are the same?

 

[777funk]

Yes that tooth on the right sure looks like full chisel, but no links have that square edge that seems to be pictured. ALL has a round edge profile. Weird because the picture sure does look it. EDIT: Looked at the picture on a computer screen and it's clear that it's just the light making the illusion of a chisel cutter.

I only buy full chisel. Unfortunately the saw came with this loop on it. Seems like lots of guys just buy what the store sells or maybe hit mud/rocks and like that stuff.

I definitely understand what full chisel is. Have used it since the beginning. Not sure why the picture looks it but it's an illusion. I spun the loop twice after seeing this discussion, and all side tooth profiles are round (no sharp square edge).

Ok, clean the gulley and file a C into those teeth.

This was sharpened on an HF grinder since the tooth lengths varied terribly when I bought the saw. Used a caplier and the grinder to get them within 0.010 of each other (and not much life left I realize) . May have to hand file to get the C back and will be close to gone by then. Just ordered an Oregon LPX loop.

Odd looking depth gauges. Never saw any with that profile.

My bet is, those are dremmeled.

Buy this.

File to the angles on the guide & use the supplied gauge to get all your depth gauges, ( the shark fins), correct.

Husky has something similar but I’ve never used theirs.

Consistency is the goal.

I use that guide as well and it works great once you learn how to use it.

OP What kind of wood are you cutting? Green/dry what species. Some wood can be very hard on a chain. I can cut 5 times the amount of green oak compared to dry pecan on a single sharpening. Are you cutting forks or strait grained wood. Forks will dull a chain faster then strait grain wood.
