Square Grinding the almost dead chains

[Del_]

I got a box of the 'Save Edge' square files from Baileys some years ago.

Very good files.

That was pretty much what I used. But without the beveled edge.

I might have to order some of these. I do like Pferd files, but they seem to be very pricey.

Much better price. What’s your review of them? Assuming you’ve used them

That's a great price.

I’ve used a dozen of them. Last 3 to 1 over Save Edge

Here’s the double bevel end profile

Is this square edge filing better than a round file? What can you do to the gullet?
That lump in the gullet will clog chips.

You remove the gullet with a round file.

Square is so much faster, smoother, and takes less power to turn the same cutter through the wood then a round cutter. To the gullet there’s a couple ways to take care of it, one is to file or grind it back round or some guys myself included enlarge the grinding wheel to grind the gullet well grinding the tooth after a certain point I will grind them back round.

imo. First do the gullet with a round file for whatever strokes needed, then finish off with only one stroke (two if it's icy cold) with your a) SaveEdge or b) one size larger round intensive cut manual file.

Regardless of the filing method used; I would NOT recommend using a chain in a tree falling situation, when it has been ground/filed below the factory set guide marks.

This square grind stuff is very intriguing. I however have not yet mastered free hand round filing so I will keep at that for now before approaching something else.

I only started round filing this year. I will continue to practice and test the square filing, but round filing is going to be my main staple for a good while.

The clear winner in price. Shipping is not bad either, and becomes insignificant when ordering 1/2 a dozen.

I thought about using a three sided file decades ago to sharpen the chain this way. One more patent I missed out on.

Missed royalties,,,,,I made all this stuff 35 years ago.

Reese style hitch for ATV’s to mount and carry, plus a winch mount.
Dirtbike rack for Reese hitch carries one bike at the rear of the vehicle.

There’s more My loss,

I watched a video this morning that showed a 1 second improvement in cutting speed with a square files vs a stock rounded filed chain. In all my viewings this speed improvement is on pare with what I see with ported saws vs. stock saws. IMO, my first, nearly blind innocent attempt at a square chisel filing is a way way improvement over a factory rounded filed chain I have ever experienced. I THINK I might have happened up upon something unique. This is based on the videos I have today viewed, and the Madsen PDF I printed out and read. I am on to something here. I ordered some files this morning and will test out my maybe accidental new process when they arrive.

You’re watching the wrong ported saw vids then. Unless they’re making 2-4 second cuts. Most saws gain between 25 and 50%.
50% is twice as fast, fwiw

Sorry this is kind of funny but it’s been ran on the west coast for 50 years.

1. This REALLY is a good deal
2. It pays to shop around a little.
