How do i file these rakers/depth gauges

[david newbie]

I just acquired 10 chains that have never been sharpened for pretty cheap. However, I just noticed they all have these weird raker. How do I file those? Just gradually shave off the top? Any ideas? Thanks

They look like they have been bent. Maybe straighten them then flat file?

They're not bent, that's how they're supposed to be.
I believe they should be filed forward from the back of the raker (the gullet) to shorten them.
I'm sure one of the chain guru's will be along to provide enlightenment...
@Philbert or @heimannm maybe...

No, not bent. There's 10 of them all the same, and I've seen this style before. It's some sort of safety to anti kick back I think, just a little fuzzy about how to file them. I'm sure someone in the brain trust here is familiar with these

This is just an educated guess, so keep that in mind... I've always read here that any anti-kickback rakers should be filed down to the same height as the corresponding depth gauges.

Vanguard style

Dumb setup for any kind of actual cutting.

You'll need patience to set them.

Looks like several of those are ripping chains given the filing angles & witness marks

Flat file the depth gauge only in that small, marked area.

Were those chains used on a ditch-witch?

That’s not nice

Never had any issues filing or grinding these drags.

A little knowledge is dangerous, get some new files and good luck, you have plenty of cheap chains to practice on

Those are too small, and I had carbide teeth on my RT-185.

 

[NSEric]

I'd use a pretty aggressive flat file for those, the regular depth gauge file will take a long time filing that much metal down.
If they take too long to file, I might even use a dremel.
You may soon find out why you got these chains for next to nothing lol.

I use this on LGX and EXL. Wonder if this will work too?

Big Box store chains. These are for the guy that uses his saw once or twice a year, and usually tosses the "something is wrong" with the chain and goes and buys a new one or two every year.

My post was a joke. I was referring to the extreme, rounded over wear on the cutters. Never saw that cutting wood, including Oak, Locust, Hedge.

Sorry, didn't mean to offend. I was being sarcastic in light of the wear on the cutters. Looks like most were run into the ground a lot.

I don't want to talk about it, still getting over my hurt feelings
