How To Learn Anything

The_Trivium's_Shield_of_the_Trinity

Trivium: Shield of the Trinity, source: Wikipedia

Indoctrination + regurgitation + graduation ≠ education.
– Brett Veinotte

What if I told you that most modern methods of teaching are deeply flawed? That the way most schools teach is misguided at best, and dangerously innefficient at worst?

Government schooling as we know it today didn’t really exist until the mid 19th century. The chief aims of conformity, nationalism, moral relativism, and acceptance of authority were the guiding principles of a system designed to create obedient workers that were so important to the industrial revolution. This system that began in Prussia would eventually spread around the globe, coming to America in 1852 and France and Great Britain by the 1880’s.

Having undergone innumerable changes and “improvements” for well over a century, we find ourselves today with a system of public schooling riddled with problems that seem too big and too complicated to fix. We are graduating kids who cannot read cursive writing, who do not possess basic skills in so many crucial areas including money management, negotiation, intellectual and physical self-defense, communication and rhetoric, social skills with people who are NOT their own age, sales, time management, and perhaps most importantly, skepticism of authority and the capacity for critical thought. We have been trained to hold up graduation as the lofty goal, without really considering what it is and just what the value of it may be.

Classical Education

Now lets look at classical education as it existed for centuries before government-run compulsory school. Classical education was based on interrelated concepts as opposed to the discretely divided “subjects” that we know of in our current educational paradigm. It was divided into 3 main areas of learning, what we refer to as the Trivium. The word Trivium in Latin means “where 3 roads meet.” The Trivium was the basis of all knowledge, it was not learning per se, but a preparation for learning. It consisted of 3 themes – Grammar, Logic, and Rhetoric, also referred to as Knowledge, Understanding, and Wisdom. The Trivium forms the basis for all learning and critical thought, and it is this systematic thought process that has all but disappeared from education.

The concepts taught in the Trivium follow a logical 3 step learning process which, when mastered, form the basic structure of thought and analysis which can be applied by the student to any subject they wish to learn. This learning process consists of Input, Processing, and Output. The input is the Grammar, or the Knowledge. This is the underlying background knowledge and definitions as applied to a certain subject. The processing is the Logic, or Understanding. Logic is the science of non-contradictory identification. The output is the Rhetoric, or Wisdom. The rhetoric stage is the application of that knowledge in a useful form.

Grammar – Knowledge

When you hear the word grammar, you probably think about english class in school, where the word grammar referred to the basic rules of the language. But grammar in terms of the Trivium is much broader, encompassing all basic facts and figures of a subject – it is the ‘Who, What, Where, and When’ stage of learning. Grammar in this sense begins with definitions. In order to effectively communicate with another human being, we both must first agree on shared definitions of the terms in use. This, at first glance, seems too basic to even mention, and yet this problem arises constantly in everyday conversation.

I’ll give you an example: the word ‘rabbit’. If I had been brought up to believe that the word ‘rabbit’ referred to a small, flightlesss bird that laid eggs and perched on a roost at night, and I came to you complaining that my rabbits had stopped laying eggs and were molting and losing all their feathers, you would think I was nuts. Now, here’s a more subtle example: there are about as many different informal definitions for ‘capitalism’ vs ‘socialism’ vs ‘fascism’ as there are broke college students waiting to vote for the first politician who will promise them “free” tuition. Ever witnessed a crazy, ranting argument on Facebook? Lack of shared definitions for words almost certainly contributed to the misunderstandings.

Grammar also extends to the basic facts and figures of a subject. For example, when learning to climb, you will see ‘kN’ ratings on carabiners. Without getting into Isaac Newton’s 2nd Law of Motion, you need to know that 1 kN is approximately equal to 225 lb. You also need to know that the Working Load Limit is 10:1 for climbing gear, or, 1/10 of the tensile strength.

Logic – Understanding

Logic takes the knowledge of the Grammar and seeks to arrange and order it, pulling out the relationships and figuring out the rules. This is the ‘Why’ stage of learning. The goal of Logic is the outcome of being able to think without contradiction, striving to arrive at ‘logical consistency’. Through the application of inductive and deductive thought processes, we derive order and meaning from the basic facts and figures, seeking the deeper truths not necessarily evident on the surface.

Knowledge without Understanding is what is referred to as ‘rote learning’. Children in school are forced to memorize all kinds of things without knowing why they need to know them. Likewise, whenever you copy something that you see someone else doing, without knowing why they are doing it, you are engaging in rote learning. Rote learning by itself might come in handy the next time you are in the exact same situation, but change some of the variables and you will see exactly why the understanding or Logic of a subject is so necessary.

(Interesting side note, if you type ‘logic’ into Google, the first 6 links that come up are for a rapper from Maryland who’s stage name is ‘Logic’. Likewise, if you type in ‘trivium’, the entire first page of search results is for a heavy metal band. Has anyone watched ‘Idiocracy’ lately?)

Rhetoric – Wisdom

Again, like grammar, when you hear the word rhetoric you probably think of school, where the word refers to persuasive speaking, or english class, with a ‘rhetorical question’. But Rhetoric in the broader sense of the Trivium simply refers to the output that one is capable of, after absorbing the knowledge in the Grammar stage, and then analyzing that knowledge in the Logic stage. If the basic facts and figures of our Grammar are true, and the rules, relationships, and premises of our Logic have removed all contradictions, then, at least in theory, we should be capable of proper and useful output. And that is why Grammar, Logic, and Rhetoric (the Trivium) form the basis of the Classical “Liberal Arts”, along with Arithmetic, Geometry, Music, and Astronomy (the Quadrivium). Because, when we are well versed in the true and proper basics, we are ‘liberated’ from our teachers, capable finally of independent and autonomous thought and action.

This is not to suggest that proper output does not require practice and take years to master. According to the now ubiquitous so-called 10,000 hour rule, popularized by Malcolm Gladwell and later shown to be a gross over-simplification, it absolutely takes an enormous amount of practice to become highly competent at any complex and challenging task. But “practice” is insufficient to obtain mastery. The correct approach is “deliberate practice”, or focusing very deliberately on the sub-skills that make up an overall skill. And yet, before we can even begin this deliberate practice, or Rhetoric, we must first be firmly grounded in the Grammar and Logic of the subject area. Then, and only then, can we engage in proper deliberate practice.

Outcome-Based Education

Now, one effective way to explain something is to contrast it with its opposite. The opposite of the Trivium is something called “outcome-based education”. For anyone familiar with the public school system, you will recognize the techniques of this approach even if you are unfamiliar with the name. For a practical example of outcome-based education, lets say you were new to this trade and I wanted to teach you how to fell a tree. Let’s say the tree in question is a fairly small, dead Maple on the edge of a bush. It has very little lower branching and a slight lean in the direction that we want to drop it. I’ll show you how to size up the lean, check the wind, cut a face, and how to make a backcut and set up a hinge to drop the tree under control, which is much sooner than if I had bothered to teach you by the Trivium method. But what if you wanted to drop another tree? This is where the difference in these two methods becomes noticeable.

Under outcome-based education if you want to fell another tree under different circumstances, you’re going to have to come to me and I’m going to have to teach you. You will be dependent upon me for everything that you learn. Now of course there’s going to be a few students who will learn by watching, and catch onto some of the techniques after a few trees, just as there are a few students who figure out some of the English phonetic code and some of the spelling and grammar rules on their own. But most students are not going to figure this out all on their own.

That is outcome-based education. You get good looking results. You get them faster, but they are shallow, they don’t last long, and what’s most important of all, outcome-based education creates students who are dependent upon the teacher for everything that they learn. Now why is that? Because they never master the basics. They only master the outcomes. Creativity is stifled because the student is never given the tools with which to create anything on his own.

Even though you had a successful outcome in that first scenario, you wouldn’t know just how many variables are involved in tree felling. Tree size, species, form, health, lean, terrain, wind: these and many more are all factors that come into play in felling, all of which you would be unable to account for.

Trivium-based Education

Now let’s compare this to the Trivium method of teaching. First, I’m going to teach you about wood fibre and grain, and tension and compression forces in wood. We might look at some basic biology of trees to see how they grow and the different layers that you will encounter in trunk wood. We will look at saw chain and how it works to cut wood. We will explore all of the different hardware and tools of the trade including different types of rope and their uses. We will learn all of our knots and look at all of the terminology, including tensile strength, working load limits, shock loading, barber chair, etc. All of this, and countless other elements, make up the Knowledge, or, Grammar Level.

Next, we are going to explore the concept of a hinge and why it works. We can then explore the basic types of face cuts and back cuts and when to use each. We will look at leverage and mechanical advantage systems, theory of using pull lines, pulling angles and tensions, wedging, etc, etc. We need to understand the ‘why’ of what we do, this is the Understanding or Logic level.

Finally, we can go out into the field and begin sizing up and evaluating trees and drop zones. We will learn how to set pull lines using throwballs and how to design mechanical advantage systems. We will learn how to handle a saw, how to aim a face, the techniques of cutting, how to prevent hang-ups, how to work on steep slopes, deal with strong winds, handle dead and decayed trees, etc. These physical abilities, the proper technique and expression of all that we have learned in the first two stages, this is the Wisdom or Rhetoric level. At this point, I could present to you that same, small dead Maple on the edge of a bush and you would know how to handle it.

Now as you can plainly see, using this Trivium method is going to take you much longer to master than if I had taught you by outcome-based education. But the long-term benefits are signifcantly different. Lets say that you want to fell a different tree. Well, you don’t need me anymore because you understand the basics. In fact, you can begin to work on your own, because you have mastered the fundamentals of tree felling, which liberate you from your teachers and allow you to adapt to a myriad of conditions and circumstances that you might face in the field. Ever wondered why Jerry Beranek’s classic book ‘The Fundamentals of General Tree Work’ is so thick? Or why it took Jeff Jepson over 150 pages to teach us how ‘To Fell A Tree’? It’s because these guys focused on a true, deeper form of education, not just an outcome-based form.

Going Deep

At the end  of the day, I am not here to suggest that outcome-based education is completely useless. For myself, the editing and production of this site is an example of just that. To build this site, I did not have to learn about transistors and microprocessors, or delve into the history of HTML, or learn PHP, CSS, or Javascript. I am blessed to be able to use simple tools that allow me to just focus on the content. Could I build a fully customized, one-of-a-kind site from scratch? No, I couldn’t, but I don’t need to. Now, if website development was my career, then yes absolutely, I had better go deep with it. Likewise, if tree work is your career and your passion, then take the time to go deep. Dive in headfirst and don’t look back. Read everything you can get your hands on. Work with as many people as you can. Teach the up and coming climbers. Strive for excellence. But no matter how high you climb, make sure you remain grounded in the basics, the fundamentals. Never skip past the ‘why’ to get to the ‘how’. You remember this and you’ll do alright for yourself.

Fiscal 36

March 17, 2017 By patrick@educatedclimber.com 3 Comments

I’m a rover, seldom sober.
(Age progression software, this is me in 10 years if I continue as a tree man…)

March 17 once again. For most, it is St. Patrick’s Day, the Irish homage to the juice of the barley and music of the fiddle. For myself, it is that too, of course, but it is also the start of my new fiscal year. Being born on St. Patrick’s Day is all it’s cracked up to be. It is time for the Guinness to flow. I am Irish on my mom’s side, by way of Newfoundland, the only true Irish colony.

It occurred to me several months ago that celebrating January 1st as the new year doesn’t really make any sense. What significance does that date have for me? I get a new day planner that I won’t use nearly enough, I get to chuck the Christmas tree out the door, and I’m left wondering what happened to all those “resolutions” from the previous January. And while all of this is happening, I’m nursing a hangover.

January 1st is an arbitrary date for me. It doesn’t feel like the start of a new year, it just feels like – Tuesday. After pondering the issue for far too long, I decided that instead of calculating the new year the way that everybody else does, it makes far more sense for every individual to calculate the new year based on their birthday. Today, March 17, 2017, I turn 36, so today marks the beginning of my new fiscal year, Fiscal 36. For people who are actually born on January 1st, well, lucky you. Your day planner was custom made for you. The rest of us will just have to make do.

Ah, the start of a new year. A time to reflect on what was, and to draw plans for the future. Here are some of the things that I was up to in Fiscal 35:

 

I signed my first Apprentice – James
I had always looked forward to signing an apprentice but the timing and circumstances never seemed right. But last year, the stars aligned and James became the first apprentice at ConservaTree. Looking forward to a great season of climbing and trimming. Glad to have you aboard James!

 

EducatedClimber.com
Fiscal 35 saw me finally taking the steps to build an online arborist resource at EducatedClimber.com and quite frankly, I don’t know why it took me so long. As they say, the best time to plant a tree is 25 years ago, the second best time is now. I bought a GoPro camera and mounted it to my helmet, I got a Youtube account, and I started producing videos and articles and building an audience. This has now become my obsession. At any given time there are a hundred videos bouncing around in my head that need to be made yesterday. And I love that I have gotten back into writing. I always felt that I could write, but for many years after dropping out of university I just didn’t really have an excuse to do it. Look for big things on the site in Fiscal 36. I will continue to provide value for my audience, through producing content for my apprentice James. My apprentice provides context for everything that I do on the site. I am not interested in talking about all the latest gear, my focus is Back to Basics. Without a grounding in the basics, you do not have a framework from which to evaluate the latest and greatest gadgets and gizmos. My goal is to provide a solid foundation of basics for a total noob to absorb that will allow them to be productive on the jobsite from day 1. That is my mission.

 

Podcasts
I started listening to podcasts in 2013 with the Lew Rockwell show, but burning a couple episodes to a CD was just too tedious. But last year I switched trucks and my new beast (’97) had a brand new stereo with aux-in and a usb port. This finally made it feasible to listen to podcasts while driving, which was a game changer. I live out in the sticks, so pretty much wherever I go is a long drive. Now I actually look forward to long drives because of the information and stories that I get to absorb. These are my current favourites:

The Tim Ferriss Show
Deconstructing world-class performers. Really fascinating stuff from one of my favourite modern authors. He literally wrote the bible: The Four Hour Workweek. Love it.

Favourite episodes:
Arnold Schwarzenegger Part 1, Part 2
Pavel Tsatsouline
“The Iceman” Wim Hof
Sebastian Junger (former arborist)
Rick Rubin
Coach Christopher Sommer
Kevin Kelly Part 1, Part 2, Part 3

The James Altucher Show – Business and life lessons from my favourite blogger.
How I Built This – Entrepreneurial inspiration from NPR
You Are Not So Smart – it’s true, and I’m not either
Smart Passive Income – Pat Flynn is the best

 

Books

Here are some of the books that I enjoyed this past year:
Rich Dad, Poor Dad – Robert Kiyosaki
The E-myth Revisited – Michael Gerber
The 4 Hour Chef and Tools of Titans – Tim Ferriss
The War of Art – Steven Pressfield
Outliers – Malcolm Gladwell
Choose Yourself – James Altucher
A Drinking Life – Pete Hamill
Folks, This Ain’t Normal – Joel Salatin
How to Fail at Almost Everything and Still Win Big – Scott Adams
The Subtle Art of Not Giving a F*ck – Mark Manson

 

Year of the Squat
I started Fiscal 35 with big plans for lifting weights. My main focus was going to be squats. I have always hated barbell back squats, they throw my balance off and they just don’t feel right. Front squats and kettlebell squats feel fine, but back squats don’t seem to work for me. I had always read that back squats are supposed to work your glutes and hamstrings, but all I could ever feel working was the quads. Also, it was always difficult to keep my heels planted, it always felt more natural to roll forward onto the balls of my feet. Fiscal 35 was going to be the year that all of that changed.

I bought a set of weights and a barbell from a guy who didn’t use them anymore, 465 pounds worth. I built a squat rack out of two skids and some boards. I started doing back squats with maybe 100 pounds but it just didn’t feel right. So what I ended up doing was just focusing on bodyweight squats. I did a lot of bodyweight squats. I focused mentally on the back of my legs – the posterior chain as they call it. I just kept doing squats and after maybe a couple of months something changed. I no longer felt it in the front of my legs, I could now feel it in the back. The problem with squatting for me was not muscular, it was neuro. I needed to wear a new groove in my brain, a groove that would allow the action of standing up to come from the back instead of the front.

So, after saying all that, I still haven’t gone back to barbell back squats, but plans are in the works my friends. I have been studying the technique and will be getting back into it soon enough. This is the video that I have found most helpful:

Candito Training – How to Squat with Perfect Form

I think it’s fair to say that Fiscal 36 will be the Year of the Squat, Take 2.

 

I found my album online

All the way back in 2003 I recorded an album at home on my computer called Waiting to Happen. A few months ago, a friend from way back sent me a link from the archives at CHRW radio, the campus radio station at the University of Western Ontario, and lo and behold, my album has been online this whole time. I had no idea. I wrote all the songs and played all the parts, audio quality is so-so, but it’s good for a laugh. All these years later, it remains, still Waiting to Happen.

CHRW Radio: Patrick Masterson: Waiting to Happen (2003)

 

Politics
Fiscal 35 was a year spent realizing that there is never a good enough reason to try to convince anyone else of your own political views. A bit of light reading about the Backfire Effect should be enough to convince us of that. My own beliefs about the values of personal liberty are evidently not shared by most. Most people, it would seem, have the desire to control everyone else. Not directly, of course, but they want to be able to choose which elected official will be in charge of controlling everyone else. Me, I just want to be left alone.

Further research: the Non-Aggression Principle (NAP)

 

Resolutions

1. Get up earlier
It seems that the only possible way to get any writing done in a house with 3 kids is to get up at an ungodly hour. For the past 5 or 6 weeks I have been trying to get up at 5:30 everyday, just so I can get some work done. I plan on making this a staple of my daily routine in Fiscal 36.

2. Daily Practice
After more than a year of experimenting, I am still in search of a short daily practice, along the lines of exercise/gratitude/journalling/meditating/writing, etc. etc. Fiscal 36 will be the year that I finally crack this nut. As Derek Sivers says, “If more information was the answer, then we’d all be billionaires with perfect abs”. Too true. See James Altucher for inspiration for a Daily Practice.

3. Drink less beer
I’m Irish. I like beer. I’m working on it. However, as old Abe said “It has been my experience that folks who have no vices have very few virtues.” Couldn’t agree more.

 

There you have it. Happy St. Paddy’s day, and, at least for me, the start of a new fiscal year. Slainte!

Saw Chain Maintenance & Sharpening

March 14, 2017 By patrick@educatedclimber.com 18 Comments

 

(Note: This is Part 2 of my Chainsaw Basics Series. In Part 1 entitled ‘How Saw Chain Works‘, I went into all the terminology and the concepts of what saw chain is and how and why it works. Check out Part 1 here if you haven’t already.)


Maintenance vs. Sharpening

There is a reason I talk about chain maintenance as opposed to just “sharpening a chain”. In my experience, I have found that anyone can grab a file and scratch the teeth and come away with something that is sharper than when they started. You don’t necessarily need to even understand what you’re doing to be successful. If you don’t really understand the concepts involved, you may be able to get away with this a few times on any individual chain. That’s how I did it for my first few years. I saw other guys filing chains and I said “I can do that”, and I just grabbed a file and started going at ‘er.

The real skill however, comes with being able to take a chain through its entire lifespan, from brand new, all the way down to nothing left, and have it cut efficient and properly the entire way. That requires real knowledge of the underlying concepts. So when I say ‘sharpening’ I am referring to a single occasion where saw meets file,  and when I say ‘chain maintenance’ I am referring to the series of individual sharpenings that take a chain through its entire service life.

Another thing I’ve found is that you will get the best results if the sharpening on any one chain is always done by the same person. I find that different people working on the same chain over time gives really inconsistent results.

All of the chain that you will be working on is called “round ground” which means that it is sharpened using round files. You can also maintain these chains using a machine grinder, but that is beyond the scope of this article. I have always preferred hand sharpening using files. I find that using files forces me to slow down and really focus on each individual tooth, and it requires me to fully understand how chain and cutters work. So, for learning purposes and for general skills in the field, hand sharpening is superior.

 

Sharpening Kit

 

A note on files – the files that you use MUST be high quality, they DO have a lifespan, and they MUST be kept rust free. So this means, buy good quality files, preferably from a dealer; take care of them; and do not allow them to be exposed to water, because once they rust, their working days are done. And even if you take care of them, they will eventually lose their bite and need to be replaced.

For a filing kit being used in the field, I recommend having at least 2 files of each size on hand. Its the old rule of redundancy: 2 is 1, and 1 is none.

 

A note on file handles – like I say, files have a lifespan, they don’t last forever. So I greatly prefer a removeable type file handle such as this one, as opposed to having a bunch of regular old-school handles. This way I only need a single handle for my entire kit. You pop the file in, use it, and pop it out. This keeps my kit nice and small.

For the best results with sharpening, you are going to want a vise. At the shop, a good solid bench vise is perfect. In the field, you can use a stump vise, or a truck mounted vise, or a vise mounted to a piece of equipment. I have seen them mounted to bucket trucks and chippers, among other things. Yes, you can sharpen a saw without a vise, but it’s not nearly as easy or enjoyable.

                                           Bench Vise                                                Stump Vise

 

File and Chain sizes

There are basically 3 sizes of saw that we use, and each has its own size chain which uses its own size file. I won’t get into the measurements of chain pitch and gauge here, but basically we use small saws for aerial work, such as the MS200, we use medium size brushing saws, such as the Stihl 26 or Husky 346, and then we use larger saws, like the Husky 575 with 20″ and larger bars.

So, the 3 basic sizes correspond to 3 different size files. The small chains use a 5/32″ file, the medium chains use a 3/16″ file and the largest chains use a 7/32″ file. Make sure before you start filing that you are using the proper size file for the chain!

 

One caveat to file sizes is with the larger chain. You can see how teeth are designed to slope backwards, so the more sharpenings they have had, the shorter they get. This is especially significant on the larger chain, which starts out using a 7/32″ file, but once it gets down around halfway, you will actually want to switch to a slightly smaller file, the 13/64″.

 

The Concept

I find it best to think about sharpening on a tooth by tooth basis. So I’m not working on a chain per se, I’m just working on a single tooth at a time.

For each tooth, the process starts with inspection. The 2 main factors to consider when inspecting a tooth are: the corner and the chisel edge.

The corner must be very sharp for the the saw to cut efficiently. The corner is what starts the cut, and then the rest of the chisel edge carves it out. The corner is usually what gets damaged the most when a sawyer hits a nail or a stone. It can require quite a bit of filing to get back to a nice sharp corner.

The chisel edge is the leading edge of the top plate of the tooth. This is the actual cutter. This edge must be razor sharp. So the act of sharpening a tooth is the process of filing the chisel edge, which in turn sharpens the corner.

The third thing to inspect on each tooth is the raker. I personally don’t even look at the raker at all until the chain is at least half way down. Some people put way too much attention into the rakers and file them down too much, which makes the saw bite in way too hard and makes cutting very jerky.

Witness Mark

There is one more definition that you need to know before we get into the technique of sharpening, and that is the Witness Mark. The Witness Mark shows you the proper angle to aim for when you are filing. This is one easy way to distinguish good quality chain. Cheap chains don’t always have a witness mark.

The witness mark has 2 purposes:

  1. by following this angle when sharpening, it sets up a good aggressive corner on each tooth, helping the chisel edge to cut efficiently.
  2. it allows you to get the maximum life from each tooth. Each time you sharpen a tooth, it gets a little bit smaller. Following the angle of the witness mark allows the tooth to last longer. If you were to sharpen a tooth on too steep of an angle, you would end up running out of top plate at the back before you had run out of chisel edge at the front.

 

The act of sharpening a tooth is the process of filing the chisel edge, which in turn sharpens the corner. It may look very simple if you’ve seen an experienced person doing it, but it is not as simple as just dragging a file over a tooth.

Now as you can see, the cutter teeth are arranged in alternating fashion, one on the left side and one on the right side. This ensures that the chain cuts evenly and straight. So with the saw in the vise, I can only sharpen the one side. When I get done working on all the cutters on the one side, then I will go back through the chain a second time, inspecting each raker and filing as necessary. I will then take the saw out of the vise and turn it around so I can work on the other side.

 

Sharpening Technique

So, first things first, it is a good idea to wear gloves when sharpening a chain by hand. If you sharpen enough times you will eventually slip, and you can cut your hand pretty bad. Secondly, the chain must be properly tensioned before you start sharpening it. You will be applying pressure with the file – the chain tension must be sufficient to withstand that pressure and keep the tooth from moving. So, like I said, it is best to work one tooth at a time. There will usually be some teeth that need more attention than others. So it is important to really inspect each and every tooth as you go.

Taking your file, fit it into the tooth, and you will see that the chisel edge overhangs the file a little bit. This overhang is how you know that you have the correct round profile on this tooth. Your goal is to maintain this overhang of the chisel edge throughout the life of the chain, never more and never less of an overhang.

 

The area where I see the most confusion and the most problems is the concept of the round profile. When you are moving the file through the tooth, you are actually grinding every surface that it touches, but it is only the very top section, the chisel edge, that matters. So, to sharpen properly, you must be able to visualize where you are applying pressure with the file.

 

Proper Round Profile Proper Application of File Pressure

Consistently applying pressure with the file in the direction shown above will ensure that your sharpening activities properly maintain the correct round profile of each tooth and will allow your chain to cut efficiently throughout its entire lifespan. Countless chains have been ruined partway through their service lives by incorrect application of pressure with the file. Some people push down too much, cutting towards the rivets. Others don’t push inwards enough, leaving the chisel edge with an improper angle, not aggressive enough to really tear into the wood.

Holding the file level, you push all the way through, trying to exactly match the angle of the witness mark. You don’t usually need to apply much pressure with each stroke if your file is good. Applying a lot of pressure takes more material off the tooth and also increases the chances of your hand slipping. With a good file, all you have to do is apply nice, steady, even pressure all the way through. I like to hold the file with both hands: the hand at the back keeps the file level and lined up with the Witness Mark while the hand at the front “pulls” the file through the tooth and applies the inwards and downwards pressure. I will explain more further on in the article about pulling vs. pushing the file when we talk about side dominance issues.

Remember, the file sharpens on the push stroke only. So, coming back, don’t drag the file on the tooth. Just return it to the starting position. If the tooth wasn’t too bad to begin with, just give it a couple swipes and then get down and inspect it. You want the corner to be absolutely sharp, and the chisel edge should be uniformly shiny and sharp.

So, the process looks like this:

  1. Inspect the corner and the chisel edge,
  2. file the tooth as necessary,
  3. re-inspect,
  4. manually advance the chain, repeat the process.

So, continue this process, tooth by tooth, until you have gone all the way around the bar. Some people will mark the starting tooth with a black marker, but I just go by colour. If the groove isn’t nice and shiny, then you haven’t sharpened that tooth yet.

Generally speaking, you are trying to keep all teeth equal size. This is not usually too big of a problem, but if you have hit something serious like a nail, it can be an issue. Sometimes you will have a few teeth with bad corners while the rest of them are not so bad. It doesn’t always make sense to file down all of the good teeth just to match the size of a few bad teeth. In those cases, I just focus on the chisel edge on the bad teeth, temporarily ignoring the corner, and over time, the good teeth will nearly “catch up” to the size of the bad teeth.


Brand New Chain

Now, this may just be me, but one thing I have noticed with most brand new chains these days is that they are actually ground with a machine profile. I think this means that the manufacturers are assuming that you will be using a machine to sharpen them, as opposed to hand filing. What this means is that the first sharpening with a round file will be as much about establishing the proper round profile as it will be about actually sharpening the chisel edge. So generally, for the first sharpening on a brand new chain, you will need to be pushing a bit harder with the file than normal.


To Recap the Sharpening Process

These are the things to pay the most attention to:

  1. Corner
  2. Chisel Edge
  3. Round Profile (proper application of pressure on the file)

 


 

Rakers

So now that you have sharpened each tooth, you can turn your attention to the rakers. As the tooth gets filed down, the chisel edge gets lower and lower, until eventually the gap between the edge of the tooth and raker disappears. At this point, the tooth will not cut, regardless of how sharp the corner and chisel edge are. The standard depth setting for rakers is about half the thickness of a dime, or .025″. Like I say, I don’t even look at the rakers until the tooth is halfway done.

The standard way to check the raker is using a depth gauge tool. The depth gauge tool usually has 2 sides, one is the standard .025″ and the other is .030″, just slightly more aggressive. In practice, you won’t notice any difference between them so it really doesn’t matter which side you use.

So you simply set the depth gauge tool flat on the chain so that the raker rests in the groove. If the raker tip is exposed above the groove, then it is time to file it down. We use a good quality flat file for the rakers, and we always go in the same direction as the filing of the cutters. Raker filing is even more subtle than tooth filing, usually just one simple stroke will do, and rarely do you need to use more than 2 strokes. Whenever you file a raker, you will also want to take notice of the profile of the front corner of that raker.  It needs to stay rounded to move smoothly through the wood. So you may need to take a swipe off the front corner with your file as well.

Now in my opinion, the depth gauge tool really only has 2 uses: it is for anyone who is unsure of what they are doing, and it is for people who don’t want to bend down and actually look at each and every tooth. I don’t use a depth gauge tool because I don’t find it necessary. First of all, you don’t need to check the rakers nearly as often as many people think, and secondly, when you have looked at teeth for long enough, you start to be able to see that gap between the tooth edge and the raker. So when I am bending down to inspect the tooth, I am seeing how the raker looks at the same time, and I can tell if I need to take a swipe off of it. One additional option to check your rakers is to set your flat file along the teeth which allows you to see the gap quite easily.

 

When you file the raker, you will be able to see a couple of straight lines on the top of it. This is how you will be able to tell which rakers you have done.

 

 

When you file a saw, you WILL file each tooth, even if it’s just a couple swipes to freshen it up, but you may NOT need to file down every raker on the chain. Do NOT over-file your rakers, you will regret it!

 

Side Dominance

So, now that you have finished all the cutters on the one side, you can set the file down, loosen the saw from the vise, and flip the saw around to do the other side of the chain. The process on the other side is exactly the same, except that everything is flipped backwards. This is where a lot of people run into difficulty because of side dominance issues. On the one side, you hold the file with the right hand, but when you flip the saw around, you have to hold the file with the left hand. So a lot of people will end up getting a different result on the one side of the chain than they do on the other.

I had to practice for years to overcome this side dominance issue but I think I pretty much have it licked by this point. My main technique for dealing with this is to use my whole body to move the file, as opposed to using just my arm. I can use just my arm on the right side but I find it much more difficult to push with just my arm on the left side. So, I basically try to lock my arm in position at my side and, bending forward at the waist, I use my whole body to move the file and basically just keep my arm stationary. The other thing that I do, as mentioned above, is I try to visualize myself as “pulling” the file, rather than “pushing” it. This way I can do things the same way on the left side as the right. These techniques have helped me to overcome the side dominance issues that are a part of filing chains, and I highly recommend that you experiment to find out what works best for you.

 


 

Well, there it is, Basic Chain Maintenance and Sharpening. I know this article is quite long-winded, but I hope you stuck around to the end and that you can get something out of it. Maintaining a chain properly takes a lot of theoretical knowledge of how chain works, and it takes a lot of practice to do it well. But it is very rewarding to be able to restore your chain at any time and have it cutting like new. It is better for your saw, and it is much better on you, the sawyer. The information in these last 2 articles took me years to understand and appreciate – I hope that I can accelerate that process for you.

Benjamin Franklin’s 13 Virtues

February 20, 2017 By patrick@educatedclimber.com 4 Comments

From the original Self-Help book – The Autobiography of Benjamin Franklin, published 1793. I have read this book several times and it continues to fascinate me. At the age of 20, Benjamin Franklin created a system to improve his character. He would focus his attention on one of the 13 virtues per week, noting when he fell short of his own expectations.

In his own words:
“I propos’d to myself, for the sake of clearness, to use rather more names, with fewer ideas annex’d to each, than a few names with more ideas; and I included under thirteen names of virtues all that at that time occurr’d to me as necessary or desirable, and annexed to each a short precept, which fully express’d the extent I gave to its meaning.” – Benjamin Franklin

The 13 Virtues:

  • Temperance: Eat not to dullness; drink not to elevation.
  • Silence: Speak not but what may benefit others or yourself; avoid trifling conversations.
  • Order: Let all your things have their places; let each part of your business have its time.
  • Resolution: Resolve to perform what you ought; perform without fail what you resolve.
  • Frugality: Make no expense but to do good to others or yourself; that is, waste nothing.
  • Industry: Lose not time; be always employed in something useful; cut off all unnecessary actions.
  • Sincerity: Use no hurtful deceit; think innocently and justly; speak accordingly.
  • Justice: Wrong none by doing injuries or omitting the benefits that are your duty.
  • Moderation: Avoid extremes; forbear resenting injuries so much as you think you deserve.
  • Cleanliness: Tolerate no uncleanliness in body, clothes or habitation.
  • Tranquility: Be not disturbed at trifles or accidents common or unavoidable.
  • Chastity: Rarely use venery but for health or offspring; never to dullness, weakness, or the injury of your own or another’s peace or reputation.
  • Humility: Imitate Jesus and Socrates.
