Rail Wear On Cannon Bar

[toolmaker]

25" Cannon bar. .050" X 3/8 chain.
This bar is less than a year old. can't tell you how many tanks of fuel have been run through it.
I am not a pro and I do not cut every day, not even every week.
Bar rails are showing some wear already. It's sort of surprising to me because of the low amount of use.

Is this common for Cannon bars?

No. @Definitive Dave

What saw? How’s it oil?

Used engine oil?

It's a nicely worked-over MS460 by Kevin.
I have not had the saw (in ported form) for even a year and the bar was brand new when the saw came back.
Bought the bar from a forum member.
Oil holes are open.
I flip the bar with every sharpening.
I run only Stihl bar/chain oil.
Before I start cutting, and every so often while cutting. I hold the saw tip near something and look for oil to be slinging while revving.
Have used nothing but Oregon LPX on it.

Mine is an older 24" Cannon sold under Woodland pro. 50ga and I did open up oil track just after purchasing it to increase oil flow. Probably over do oiling, but always turn oiler up so I am using about 3/4 oil tank to fuel tank. Rails are hard and have only clean sides once and had to use a grinder, my files would not touch it. Normally use a Pfred bar dresser. Soil here is sandy and see sparks every now and then. Run on a 372 and 390 mostly.

Is the wear just on the heal of the bar? Is there any wear on the tip right after the chain straightens out?

 

[toolmaker]

Both places

How’s your sprocket? Maybe bump up to 8 pin?

 

[toolmaker]

sprocket looks ok
whty would an 8 pin do?

 

[Ketchup]

Widen the angle the chain enters the bar. Probably makes no difference.

Both places

I find that those two places take a lot of damage when running the chain too loose at high rpm a lot.

Normally cannon bars are the best wearing bars on the market, from my experience.

I’ve heard Used engine oil will wear out an Oiler quick

Fix’d

Reminds me of this photo.

The black standard weight ones? Maybe this new material isn’t as durable?

Loose chain slap

 

[toolmaker]

Sorry guys. I don't run my chain loose.
I also don't piss rev any of my saws without load.

 

[Nutball]

Too tight???

You'd think Cannon would super harden the rails back there like a hard nose bar.

Ive only ran the standard ones. You’d think the steel and rails would be the same?
