How to square file

And I take from the back of the raker to the gullet... maybe 10-15 seconds

I just did this a couple nights ago for the 1st time. I used a raker file and it didn't take long. 15 minutes maybe on a 20" chain.

Takes about 2 seconds per rakers with the grinder and 6" .045" wheel.

Oh yeah I could see that. Someday...

We use them all the time to cut and feather tacks and stuff. I'm used to them. A cut off wheel in a Drexel works but takes longer and you have to change wheels.

I used a 6" cutoff wheel when I did the race chain. Used it to trim the rakers, thin the cutters and on the rivets

Just a curious question. What actual good does it do to clean the gullet out well ahead of the cutting edge? I understand "under the tooth" but why would you wanna go all the way forward to the depth gauge

Less weight and more room for chips.

Seems to me the chips wouldn't back all the way up to the raker. I see the weight issue when looking for pure speed. I don't do square myself. I'd love to see a super slow mo video of a cut that is only taking out a "kerf" width of the outside of a log. So you could see exactly where chips do and don't build up. Food for thought. If any of you fellas ever see a video like that post that sucker up

In theory after you square file. Could you then hit it with a round file , without hitting your working corner. And undermine it to also speed up the cutter to help the chips get away. Sorta make the hollow grind Obviously you wouldn't wanna mar up the finished edge but if you stayed low it looks to me like you'd end up with a good area for the chips to discharge

Cut down into a log making a cookie and kill the saw mid cut with pressure on it so it's cutting good. Break the cookie off with the saw still there. It's easier with a 2nd person.

Kinda hard to show in the picture but the working edge of this round job here is way different than the undercut I've made beneath it the working edge is blunt. Sharp but blunt compared to what is done under it. Anyone tried that? I feel it cuts faster considerably. The edge being left blunt also leaves the durability intact. Sorry if I'm off topic this being a round job. It is fairly fast it's just something I don't fool much with. It would cut some extra weight out also if you're counting hens teeth

Kinda maybe?

I see. There's no more question that is razor sharp there's no need to round it any Didn't actually realize fellas took quite that Angle with square files. Some of the pictures I've seen had way less angle than that. However it looks like you can certainly shave a tooth down to razor blades with a square file. Where I was at in my head is a whole different approach than what I can explain Keeping a durable "point " then beveling it with the round for flow without giving up the durability

Kinda wish I had a single square file laying here I'd do what I'm thinking in my head and post it

I c, thought you were talking about the gullet area. Your just tunneling under the top plate.

Yes and catching the side plate Without touching the actual corner

 

[jakethesnake]

Similar to what's in the picture
