Hand filing square files chisel chain

[@jtownsend220]

Thank you! I was wondering why all of a sudden my teeth were laying back. It was driving me crazy. Everything was sharp but didn’t cut well at all. You gave me the answer I needed.

You could be a KZbin sensation with your excellent communication skills. Your clear communication, excellent use of close-ups, and to the point instruction is what so many are missing on KZbin. Thanks so much!

Thank you and your welcome. Glad you found it helpful.

Thank you, I’ve been struggling with this, mostly to get comfortable. This way looks way better.

Thank you John, that was a very informative video. I particularly like that you explain the mechanics of how things are designed to work instead of just saying this is how you file a chainsaw. Makes more sense when you have the whole picture.

[@jeremyromine9718]

This is very informative. It never occurred to me that I was changing the angle of my top plate. I did not understand my chainsaw tooth completely until now. Thank you.

John ... you are completely right ...however most of us are never going to have the eye or ever develop the skill set you have. For sharpening working from up toward the tooth working point ( my saw is in a vice at home .. ) I find my tooth doesn't move as much as going the other way And I can align the file to working point easier. How you can sharpen square ground by hand in the bush is something I can never do. You are the man.

Thank you sir- truth is, I haven’t hand filed for 35 years. I use a Silvey SDM- 4. The precision I can get with the grinder is more consistent and much faster. I just swap chains out and save the sharpening for a rainy day.

@@LGTrees quite right ... we reach for the bag with the 2-3 spare chains. Hey thanks for bringing up square filling ... I never knew about it till I watched bucking Billy Ray cut through a log and thought " this is something different ..its cutting way way too fast " Eventually he did a video on the 451C and it all became clear. Now 2 years later I've got one as well ( would have to say the Silvey looks like the nuts ) I'm still learning but have had an experienced logger come up to me mid cut, wide eyed and go " what's going on there with that chain, look at the size of those chips" Hardly anyone knows about square grind.

My dad was a forty year tool sharpener and a faller/bucker..He was old school and always told me to file against the tooth instead of the undercut like you teach.You have to have the sharpest file to do it his way..I can see more and have more control your way...Thanks so much.

[@aktrapper6126]

You covered all the angles well, never heard about the tooth changing angles as its cutting but that make perfect sense. Thank you for the lesson.

[@bobgalaz7901]

Thanks for taking the time and sharing facts without bs

Excellent video. I discovered square filing a couple of months ago on Guilty of Treeson. You are the first one to mention the 5* forward angle on the side of the tooth, and it make perfect sense. Do you recommend the file type that you used or have you used the "triangular" files also? Have seen several people trying to file by filing into the chrome plated side of the tooth and it destroys a file quickly. thanks, Ken

If you just trying square file by hand- the goofy file is best. Has a slightly rounded edge on the side plate. Madsen has them. I file out of the tooth because I can see what I’m doing and saves the file edge. There are pricey.

👍👍👍

[@bertjacobson9550]

Your awsome friend ty 👍👍👍

[@felipesandoval7593]

Well I used a square files not a tapered to experience this PHENOMENON.AND SOB WORKED ITS SHARP AS HELL .DAMN CHAIN ATE UP MY MESQUITE QUICK .SO IM STILL TINKERING AROUND WITH IT.

[@brodyhunt6329]

Good video. I stick a falling wedge in between bar and chain instead of tightening entire cutting assembly, and then move it along as needed. I reckon it would depend on what position you like to file in, as to which method might be quicker.

[@Surtac100]

Thought the side plate was straight up and down or 90degree to top plate, that’s why it’s cAlled square file. I could be wrong that’s why I’m asking.

[@LGTrees]

Tipping the side plate forward 5 degrees makes the difference between cutting “OK” and getting that little extra. One of my other videos, I explain how the tooth tips backwards a bit when it hooks into the fiber. If the side plate is 90 degrees to the bar to start with, then it is tipped backwards a bit when the tooth is actually cutting wood.

Where are you getting your files for $9? I am in Canada and the ones I can find are about $40.00 for ONE by the time I get it here. THAT is what we have to put up with here.

[@LGTrees]

I purchased a couple from my local saw shop just to make the videos. He sold them for 9$ each. I just checked Baileys online- $15 each. I normally use a Silvey SDM-4 grinder. Haven’t hand filed for years. The Simington seems to be the go to grinder now. Check out Madsens Logging supply. Lots of Good information there.

[@outboardfixer]

@@LGTrees Thanks for the reply John, I did see the ones on Bailey's but they want 27.00 to ship ONE file up here...just can't bring myself to do that. I will check Madsen's. Thanks for the great video.

[@justinr6200]

Great video. Where do you get your files. Nothing beats a square grinder chain. First time I tried a square ground chain in the northeast was during the game of logging.

[@gregwright2867]

Great instruction John. We need more and a better shot on your method as you do it !

[@dustinjohnson3463]

Thank you sir for not putting it in a vise it's just as if I were in the woods find a log or stump a beer go at it .

[@waynetetley584]

Nice explanation. Thanks

[@woodcutter4481]

Nice video. I file all my chains out of the tooth.

[@JohnWalker0507]

Thank you sir
