Accuracy VS. Cost - BATTLE of the Speed Squares

[@marcellemay7721]

I've been a finish carpenter for 40 years now. Marking the line properly is important, but actually cutting it on the line proves to be way more difficult than the accurracy of the actual line. If you need to make a bunch of cuts at a consistent length, a stop is the way to go. And then be very careful when butting things to the stop so as not to knock it out of whack. Personally, I don't think that a $200 square is gonna make me me a more accurate woodworker. The techniques and experience I've gained over the years far outweighs the price and performance of high end tools. What's most important tools in general is that they can hold their settings once set to a accurate 90 degree for instance. One can perform some very beautiful and accurate work with modest tools if he can learn the limitations of the tool and work around them. A $3000 table saw will not make a novice into a pro, but it just might allow a pro to produce accurate work more quickly and efficiently.

[@lincolndickerson1293]

At the end of the day, can you see gaps in your joiner? If your Swanson speed square or you 30 year old Craftsman combination square leaves no gaps in your joinery then do you need to be more accurate? If they do step it up. If not, bring on the next measure, mark and cut item. Frankly you can build super tight things with story sticks and and a marking knife. Are things like Woodpecker and Incra more accurate? Yes. Does it matter? Your call.

[@angrybeaverwoodworks]

I 100% agree and I love the way you worded it. I stepped up to the I-Gaging because I really wanted to get away from basic framing speed squares. I think my new selection will be just fine and it didn't break the bank. Thanks for watching and commenting.

[@cuebj]

@@lincolndickerson1293 Ha ha. I just came from watching a video about Gemeral Theory of Relativity, Quantum Mechanics, and Gravity. Measurement, location, reality - boil down to infinitesimal accuracy of woodwork measurement rendered of doubtful relevance in face of wood movement with moisture, heat, compression against material it's fixed to, etc. I've managed both construction and fine furniture woodwork with basic set squares for 50 years. Are they true 90⁰ to 1000th degree, No. Should I replace them? Possibly. Cabinets in old UK housing stock need an element of plasticity so dead square looks wrong

[@Kami8705]

I agree completely. It also depends on what your building, even if you don't include building framing. On top of that, wood changes based on humidity and temperature, so it won't matter in the end. Also, paper is generally 0.002 thick, and unless you're a very experienced machinist, you won't get past 0.001 accuracy, and it doesn't matter for a lot of parts. Any of those squares work fine, although I've found some older abused ones especially that disagree with each other by 1/4" or more, and that does matter. Beyond that, buy the quality you can afford and spend money elsewhere

[@grantjackson21]

Preach!!! As a newbie wood worker I was constantly confused at why my “perfectly” measured and marked dimensions resulted in huge gaps and wonky surfaces. Must be my crummy tools… little did I realise I wasn’t using the same reference edges, same tape or rule or was cutting on either side of the line. Spent hours researching “crows feet”, buying ridiculously thin pencils. Still daylight between joins. Takes a lot of practice to put a piece of wood against a blade and cut straight. Most often than not the measuring tool and the cutting tool are perfectly adequate, the person holding those two however is what makes the difference

[@milttaylor3898]

Great Video. I am a retired precision machinist and I can tell you there are numerous ways to check a squares accuracy. The easiest way I have found is to select a flat surface (your table saw surface works quite well) and face a known accurate square (fixed Machinist Square or 1-2-3 block) against the other, measure the gap between the two squares (feeler gages work well, 1 degree equals approx .017 per inch). I agree it only matters how accurate the tool is, when setting up your machinery. 1-2-3 blocks are almost a necessity in your shop, they are extremely accurate and serve as a perfect 90 degree standard.

[@brianm.9451]

When I first started woodworking, I followed a lot of influencers who had Woodpecker products and, like most n00bs, I, too, dreamt of the day I could purchase them. I own precisely one Woodpecker product and it's their centering ruler...which I barely use. On the other hand I do own two combination squares and a double square. One is a Starrett combination square, one from PEC and my double square is also from PEC. Seeing your video brought back some memories and thoughts: my PEC cost me less than $40 each. My Starrett is the most expensive one but I use that for calibrating my table saw. For layouts, my PEC squares do well. I found that it doesn't matter how accurate my squares are if me cutting with a handsaw is less than stellar. I have three squares I use for calibrating tools and for making jigs which help me not just accurate but repeatable.

[@Brian-dr2yi]

[@alschroeder1724]

One thing to remember about Woodpecker and the KZbin world.....They give content builders their product to advertise the name. If 90% of the KZbin builders had to pay the Woodpecker price most wouldn't. But the average user watching assumes the "need" of a $200.00 square. I always relate back to the fact that Stradivarius built violins with hand tools in the 1700's...fairly sure they didn't have anything down to ten-thousands of an inch.

[@Swarm509]

Yup, to me this falls under the realm of understanding the material you are working with. You can be very accurate in woodworking, and have to be for some things being made, but wood will always be a "living" material that moves, twists, grows/shrinks out of our control. Even the machine only woodworkers will only be so accurate compared to someone working with metal in a machine shop. This comes up all the time in hand tool only communities with people wanting to be as accurate as a machine, it is possible but not worth that effort for many jobs. "flat enough" and and "square enough" are things that need to be learned and understood, especially when doing things by eye and hand.

[@vicjs216]

I am writing this on a desk made by my granddad in 1921. The dovetails are still tight, leg mortise and tenons solid, and the draws still glide with ease. I inherited his tools- planes, chisels. saws, winding sticks, and bits and brace. Measuring devices- 3 dividers, unmarked straight edges, winding sticks , string, plumb bob and a wooden handle home made square (no measurements). Not sure if he knew the knew the difference between .01 or .0005" but know he would find it crazy to spend more on shipping and measuring tools than investing that money into good quality wood. I have resisted the urge to buy red tools but have poured money into a lot of other somewhat less expensive stuff. Results, my mortise, tenons and dovetails are far from picturesque. As the old saying goes, it isn't the tool but the man (or person to be pc) behind it that makes all the difference.

[@johndennisjr.4975]

Two comments from a retired Physics professor who now enjoys woodworking. 1. Everything you said about expensive red tools is true, although they do offer pretty wall mounts. However, the accuracy of measurement (or lack of) is dependent upon how much is “added” to the error. I recently was in charge of a church project which had us building a handicap ramp. I had to show my helpers why we needed to check the square of the 4’ deck boards often so we wouldn’t end up with a fan. After 5 boards it became obvious. 2. Please refer to another KZbin video entitled “Adam Savage’s Epiphany on the Science of Measurement”. At the end of the 45 minute video, you will know why there is absolutely no exact measurement which can be done by human hands or man made instruments. To the point… everything is an estimate. We have 360 degrees in a circle because we KNEW that it took 360 days for the Earth to go around the Sun. Opps.

[@johnrako]

It would do us good to remember that some of the finest furniture ever built was made with hand tools, laid out with wooden rules and cut with hand saws, planes and chisels. Moreover, wood, and even steel, "breath" or move with temperature, humidity, and time. To my limited knowledge, I doubt that anyone ever checked to see if the sides of King Edward's writing desk were parallel to one thousandth of an inch. We should strive for accuracy but not obsess. This is supposed to be fun.

I have a number of woodpecker, starret, iguaging and other brands of layout tools and I will say that woodpecker and Starret tools add nice creature comfort features to their tools that other cheaper brands either don’t have or imitate badly. Things like engraved lettering and low glare metal that is easy to read under bright shop lights, positive locks that make it’s easy to trust the setting of a tool even after it’s been in your apron for a few days, cutouts for the kinds of marking tools woodworkers keep in their shop and others. I am not saying I want to replace all my tools with a wall of red but for a few what I consider cleverly implemented items they are nice to have.

[@JustinShaedo]

It's wood. Measure it's thickness and I guarantee a week later it will be more than 0.004 different. If you want that level of accuracy use metal and get a high end laser CNC. Otherwise it's simply paying for ignorance (not understanding that wood changes depending on humidity and temp) or bragging rights. Excellent video.

I have been told that my work is amazingly accurate and precise, too. (Told by a framing shop, btw.) At those tolerances, glue squeeze out make more of a difference in square than the cut!

[@Tensquaremetreworkshop]

Very entertaining! As you say, it is not the marking out, it is the cutting. The most accurate work is never marked out- the machine tools set the precision to be achieved. Most of all, thank you for introducing tolerance to woodworkers. As a sometime machinist, I rail on many channels at the use of 'perfectly square', exactly', 'spot on' and other superlatives. Everything, of course, has a tolerance and keeping that in focus always benefits what is (and can be) achieved. Accuracy costs (both in time and equipment) exponentially as one gets closer - and wood moves. Getting a value more accurate than it will have moved to next week is pointless. Tolerance therefore widens- engineering drawings have marked tolerances on all critical dimensions, wood drawings not- but then much of woodwork is still in the hand fitting era.

[@carlmclelland7624]

Hi "Angry." A good, poignant video regarding the accuracy of tools. I've compared many of my woodworking tools to my machinist tools, and for wood, the woodworking tools exceed my standards (and ability) for cutting and assembling. You hit the nail on the head when you said, "The ability to cut." Now sink the nail by adding, "The ability to assemble." As an experiment once, I 'routed' some wood on my milling machine, and then duplicated my efforts on my homemade router table. You can't tell the difference. I like your show, buddy..., you earned my subscription.

[@Tensquaremetreworkshop]

So, I'm in love with accuracy. I have many extremely precise references, and I love them all, with my metal working projects .0001" is a very tiny slice. When I first started woodworking I was passionate about "accuracy". Today, I know that far more important is to plan and cut your pieces using a reliable reference or jig. That along with wood being organic, it moves, anything you do, no matter how accurate, it's temporary. For example, if you need to cut drawers? Cut all the sides to width at the same fence setting. Legs? Set a saw stop and cut them all to length. Exactly to your point, the mark means nothing: it doesn't guide the chop saw blade to that super-precise square cut.

All of my squares will nest inside of each other without any light visible. FWIW L S Starrett tools are designed for engineering and machining applications so a little more accurate than required for woodwork but there is never any doubt. Plus they will likely outlive me.

[@GraemePayne1967Marine]

I picked up woodworking again after retiring from a career in metrology - the science and practice of measurement. In my view, the precision requierd from the measurement tool depends on properties of the material being measured. In this case we are talking about wood. It is well known that most species of wood expand and contract due to seasonal changes in humidity. In most species, those seasonal changes are considerably greater than the specifications of the measuring tool being used. Also, metal measuring tools change dimensionally with changes in temperature. I generally don't obsess about the measurement tools, because I know the wood movement is greater. On the other hand, I do control the enviroment in my shop as well as I can afford to. Not as tight as a calibration laboratory, but as stable as I can make it. That will minimize the temperature effects on the tools, and the humidity effects on the wood. I have a variety of precision dimensionsl measuring tools, acqiured over the span of thirty years or more, from a variety of suppliers ranging from precision tool manufacters to Harbor Freight and thrift stores. Most important is a * sharp single-bevel marking knife * to make layout lines on wood. Technically it it not a "measuring" tool, but it is ESSENTIAL for making the layout lines on wood. A pen or pencil is fine for notes, but not for knowing precisely where to cut. Micrometer, dial caliper, digital caliper, thickness gauge, a set of metal precision dimensional blocks, a pair of steel 1-2-3 blocks, a granite surface plate, dial indicator and base, a set of three machinist squares (from iGaging), precision straightedges in three lengths, several spirit levels in lengths from 6 inches to eight feet, feeler gages, digital thermometer (*** a table of emissivity values for materials you work with is essential for this!), a digital tachometer, an anemometer, a variety of steel rules, a Woodpeckers "Mini Square" (rarely used!), three sizes of speed squares, and recently acquired an excellent Starret combination square with a protractor head from a retirement/moving sale. I also have a set of machinists drill bits in 1/64 inch increments - the shank end of those can also be used as precision measuring tools. Most of these inherently have more more precision than I consider "necessary" for woodworking. A number of these tools are ones I do not actually use on wood. Instead, I use them to verify the precision and accuracy of tools that ARE used on wood. For example, to verify that a square is actually square, or that the blade of my radial arm saw is actually square to the table and/or fence. Also, all of my "precision" measuring tools are kept in one drawer, and most of the others in a different drawer - and a small number hang on the wall. Finally there are the plastic right-angle blocks used to align & clamp boxes & cabinets. They are not strictly "measuring tools", but they are used during assembly, so I use a machinist square to verify them before use, as well. Key for me is to know what to realistically expect from a measuring tool, and periodically compare to a "better" tool. After all, for thousands of years woodworkers did not have access to the type and variety of dimensional measuring tools available now, and many turned out work that even today are considered examples of excellence.

[@TheMrAshley2010]

Years ago I apprenticed as a tile setter, working on very high end remodeling jobs. As the guy cutting the tile that the master tile setter marked, I quickly learned that I needed to know if I should make the cut ON the line, to the LEFT of the line, or to the RIGHT of the line he made. Sometimes when fine adjustments to my cuts needed to be made he would ask me to recut the tile and only take off material equal to half the thickness of the saw blade. Context in defining accuracy is where it's at. Good video!

The proper way to test all the squares would be a cylindrical square, surface plate, feeler stock (down to .0005"), and prussian blue.

My approach is two fold. 1) you can do the “score a line and flip” test to check for true square on a cheaper carpentry square…if it is a bit out you can true up the outside angle with wet and dry until it is bang on correct….This can make a useable silk purse from a Chinesium pigs ear. OR -- 2) Buy one, super accurate square, like a Woodpeckers tri-square and use that only for joints that require such accuracy. To this end I have a 300mm Woodpeckers square for if I really need it (a luxury purchase at US 140 bucks) …and a good brand name (DeWalt)Rafter Square that is close enough, for everything else. BTW super accuracy on a tiny square is pointless…the angle of error multiplies with distance…and since you only sight the square by eye with its limited resolution anyway….how would you know if your saw blade was off by half the width of the finest pencil anyways?

This is a good start, but there are further clarifications needed to really understand the issues. First? Within .00XX OVER WHAT DISTANCE?! Just a number means nothing; there HAS to be a scale as well. If it's accurate to a thousandth over.... a THOUSANDTH, then that's not terribly helpful is it? Second, how accurately you can dial in your tools is also a factor, but remember that some power tools are scary accurate... (I have a sliding table saw that holds .003" over 10.5 FEET...) so you CAN cut accurately, and hand tools count as well. Planes can easily take shavings well under the thickness of that piece of paper. Finally, it's also important to understand the issue of the multiplicative error. If you're making a box, you don't need ONE 90º angle; you need FOUR. If each is off by a few thousandths over a short distance, you will easily see a gap when you put it all together at one of the corners. Ask anyone who has ever made a picture frame how difficult it is to make sure that all four corner seams are closed up correctly. Shooting board anyone? So, with all of THAT in mind, the woodworker should select the quality of tool that they need for the nature of their work. Fine inlay and veneer needs accuracy to that .001 level; as your fingers can feel the edges/ridges when things are not flush. On the other hand, a shop bench drawer can probably be out of square 1.5º and not really cause a problem. Pick the tool calibration needed for the work at hand, and remember that ALL of these are probably not accurate enough for truly precise aerospace machine shop work. It's all relative!

[@KnottyBurlWoodworks]

You bring up a lot of great points when it comes to accuracy of your tools. Let's be honest though...Woodpeckers buyers aren't always buying for accuracy, but more for job specific tools. I don't own a lot of them, but I own a few. My DelVe square is great at its primary purpose...laying out mortise and tenons. If you're laying out a ton of them, the design of that tool is perfect. However, I think there might be a lot of buyers that buy just for the brand and the influencers they follow. Regardless, great video and great info!

[@brock9872]

Agreed, the few woodpecker tools I have are specialty tools. I plan to buy a couple more. I wouldn't spend that kind of money on the majority of tools but some stuff is worth it to me.

[@ryanluvaas4097]

yeah the Delve square has a lot of neat/nice features on it that make it very convenient and improve efficiency. The speed squares I own lack those additional features.

[@msk3905]

I am a DIYer but also an engineer so accuracy to me paramount when i build furniture (actually just helped my brother in law build his deck and he kept telling me measurements don’t need to be down to 1/16”). I’ve looked at woodpecker products and wanted then but i think that their price point is too high so I’ve sought out alternatives. There are many options at much better price points, i’ve recently come across another KZbin page “hooked on wood” who has a series reviewing China tools, if you haven’t seen this you need to! I have bought several items and I’ll put them up against Wood pecker brand!

[@naznomad635]

I do tend to use a machinist's square to mark pencil lines on wood that I'm about to cut with a saw that has a 3/8 inch kerf.

[@carlboe8778]

I like the commentary, very good. Just a little comment from a recently retired tradesman. Protect you tools! Regarding precision equipment: Drop it, bump it, etc. It may need to be repaired and/or recalibrate. In this case we're you taught to correct the variance of your specific squares. I've done it for 40 years, and I won't try those tolerances without sending it to repair shops.

[@Sagart999]

If I may suggest a better way to determine the accuracy of a speed square, machinist's square, etc.: Lay out the two parallel lines with a single bevel marking pen, as described in the video. But before doing so, lay down a piece of blue tape and then roller it into the surface as if you were trying to ensure a very nice plywood cut. After making the two cuts you believe to be parallel, remove the tape between the lines. The tape will make it far easier to see the edges of the lines. The next step is to ensure you actually measure across the parallel lines consistently. Lay the square against an adjacent side; it does not need to be perpendicular to the first side. but it does need to be straight. You can now use the arm of the square as a guide when using the calipers to compare two locations along the parallelogram. Otherwise, you may very well be adding errors to your investigation.

[@Argyll9846]

I've been looking at Woodpecker products for years and never bought one for two reasons: 1. Their cost 2. The accuracy they claim is simply nuts when it comes to woodworking. Were not making precision Swiss watches we're making tables, chairs, boxes, toys etc. etc. etc. Fine accuracy is generally mandatory for metalwork but not woodworking.

[@horatio71]

I'm a pure hobby woodworker. While I aim to be as accurate as possible I actually find that more important than the accuracy is the consistency therefore I do like the squares with marking holes. Just to be clear when I say accuracy I do want my 90 degree angles to be a 100% accurate, but if if a drawer is 10 inches wide or 10.005 inches wider does not really matter in my opinion.

[@angrybeaverwoodworks]

That's a good point. You are referring to what the woodworking community refers to as RELATIVE MEASURING. Don't know if you've ever heard that or not. It's a good topic that I will be discussing in future videos. Thanks for watching and commenting. I hope that you enjoyed the video.

[@Dickie2702]

You speak the truth young man. On the basis of all the KZbin Makers that have sold out to Woodpeckers and by their popularity sold alot of product for them I ask myself this? How the he'll did I make a living for decades when all I had was a set of four steel engineers squares, a sliding bevel, a very accurate combination square, steel rules, an analogue vernier and a marking knife? Beats me how all those pieces I sold that were so inaccurate never just fell to pieces. Must have been good glue, which by the way is another complete nonsense in today's climate. Woodpeckers are the woodworking equilivent of Apple. Great video I hope it influences alot of people. Now I'd to see a video on relative dimensioning as that is the best way to get consistency in any piece youmare making.

[@in2rock275]

I build boxes that my friends and family gush over using layout and measuring tools purchased at the big box stores. Sure, I've bought a few high end items from my local Woodcraft store but they really didn't improve my work that much. The main point, as was noted in the video, is the accuracy of set up on your power tools... mine mainly being a $300 DeWalt table saw. I've spent long periods of time trying to "dial in" that blade to a perfect 90 or 45 (hasn't everyone at some point?). Regarding the 45, once I learned to cut one piece on the left side of the blade and the other on the right to make my miters for my box corners, it really didn't matter that much. 44.5 and 45.5 still add up to 90.

[@davidhorizon8401]

That 45 miter idea is brilliant. Don't know why I never thought of it. Probably because I am not brilliant!

[@angrybeaverwoodworks]

I agree

[@angrybeaverwoodworks]

I agree with David's comment below. I've seen and used that angle trick when I could get my jointer dialed in to a perfect 90. I labeled each side of the wood with the A/B trick and flipped the wood. I have never thought about the same concept on mitered joints. That's pretty genius. Nice trick

[@rodpotts2666]

You are spot on!

[@mikeking7470]

One other factor is the material we use, wood moves, it expands and contracts. I have seen this for years on forums, people boasting about cutting to 1/1000th of an inch, forgetting that their wood can expand 1/8th of an inch across a table top or shelf over night,

[@angrybeaverwoodworks]

I'm glad that you mentioned that. You are absolutely correct. Wish I had added that to the video, but thank you for adding it here.

[@Techreux]

Nice to see someone else hasn't drunk the kool-aide. Woodpeckers is priced SO high to me that I can buy a tool instead for all that cost! Agree 100% with the machinist's square - absolutely essential.. and inexpensive. A fraction of the price. Absolutely correct that you can't cut as accurate as you can measure. We all know plywood ain't square, and that timber has lots of runout, flatness issues, and such. I know when I tolerance a job for a customer, I make it as high as +/- .125", and the tightest I will spec is +/-.0625". The only reason I need squareness is in how things fit together, so that the item will sit reasonably flat and perpedicular on a surface when completed. But, trying to maintain sheet metal accuracy in wood seems crazy to me.. and I've done both for more than 45 years. Thanks for a great commonsense video!

[@angrybeaverwoodworks]

Thank you for the kind words and all of your input. I completely agree. Thanks for watching

[@jacobburkett]

I'm on disability because of a ridiculous number of back surgeries. I've been woodworking for the past 8 years and I just recently got a thickness planer. Second hand I might add. All my tools including measuring have all come from Harbor Freight, Lowe's, Home Depot or Amazon. I'm sure Woodpeckers brand is nice and I'm sure I would agree they have amazing detail. Do I believe spending that much money on a tool would make me a better woodworker ABSOLUTELY NOT! In my biased decision I have put out quality work with the tools I own. My experience does not have anything to do with how accurate or how much detail is in a product, but more so my knowledge in how to use the tool effectively. In fact I have not had one individual tell me they were never pleased what I made for them. I'm almost willing to guarantee if you talk to an older generation woodworker, he would tell you a tool is a tool. Just my honest opinion

[@skyehagen5521]

You hit on the real key point towards the end. It's the accuracy of your cutting tools. Following from that point, determine what measuring tools (or cutting jigs) are needed to ensure the accuracy of your cutting tools. To ensure the accuracy of my cuts, I have a machinist square, and a digital tilt meter. For crosscuts, I have a miter guage and a Dubby sled. For planing, I have digital calipers. As for measuring, I use rules, a tape measure, or 1-2-3 blocks and setup bars. But generally, they don't have to be accurate, because after the initial cut, most everything is measured using relative dimensioning, or jigs.

[@angrybeaverwoodworks]

You....like so many others have been talking about RELATIVE measuring. I wish that I had added that to the video. I think I could bring up that topic in some future videos. I honestly tend to use a lot of different jigs and sleds. I've been building new versions and upgrades to all of mine since I have revamped my shop. I appreciate you commenting and thank you for watching.

[@markkoons7488]

With several sets of digital calipers I imagined I was encountering poor quality because, by the way I was using them, each needed to be reset to zero when the jaws were closed. That was true for the $20 no-names and the $140 Mitutoyos. Then I learned to wipe the contact surfaces when I closed the jaws and found they all returned to zero and gave identical measurements throughout their range of measurement. In fact, I came to prefer the no-names for some woodshop applications because they'd toggle through fractional inches as well as metric and decimal imperial. The fractional inch capability is extremely useful for selecting drill bits for pilot holes.

[@brettleisy356]

I never automatically believe a company when they say they do something, they can stretch the truth quite a bit without being called out. I only hold partial weight of someone saying "it's totally off" as there is a high chance of human error and/or stupidity, unless they prove it. I was really hoping on seeing actual testing here. a feeler gauge that has been double checked by a caliper or better yet multiple calipers. I bought a professional grade self leveling laser level (few hundred dollars new), set it up, tuned it close as I could, then turned it on and found that from top of the door to the bottom of a door it looked way off. so tested it by tying a string on to a nail and a nut at the bottom. yeah, I went old school on it. the door was crooked but so was the laser, it was about an inch and a half- inch and three quarters off. even with full adjustment to the unit I couldn't get it "level" until I shortened one sliding leg... by a LOT. I got a more accurate reading from an app on my phone sadly.

[@markbell335]

I classify myself as a woodworking hobbyist since I've never made a dime off of the stuff I've built over the last 50 years. My first power tool was a Montgomery Wards 10" Radial Arm Saw I bought back in 1972. This machine became the backbone for most of my wood working from the early 70's to about the mid 90's. I now use a 10" Sears Craftsman sliding miter saw for most of the stuff I do these days. I use a 1974, 6" inch, vintage Sears Craftsman jointer to true-up my boards. I purchased this when I had to build cabinets for my kitchen back in 1974 .... the jointer wasn't vintage when I bought it.... but after all this time ... we both fall into the vintage category. Regarding my layout tools I own an Imperial tri square that I've used for years. I didn't realize it wasn't quite square until I bought a Starrett 6" combination square and compared the two..... which means I had to buy yet a third square to verify the accuracy of the Imperial and the Starrett.... I now buy Starrett tools.... I also buy PEC seconds when needed and available. I've built a ton of stuff using tools that fall into the 'Not for Snobs' category. All of my projects have held up very well over time.... by the way, I still use my imperial tri square because it has a steel blade and never worn down after all these years. Mark Bell

[@acarpentersson8271]

You asked for a better method to do this particular thing. Get 2 of the squares and put them in place and use your calipers to measure between them. No marking required and you are absolutely measuring to the square. That being said, we frame, we trim, and we build cabinets. We use the same squares and the same tape measures, and the same saws. Of all the professional cabinet shops that I know, which only do cabinets, they all use the same tools we use for framing, trim, and cabinets. Save your money. As you pointed out, the pencil line is anywhere from 0.09 to 0.05. How accurate is your saw, and how straight can you cut? No one will ever say, that cabinet you built, I'm sending it back because it's 1/16 out, much less.004 out.

[@gregwilliams7354]

I'm embarrassed to say my speed square is from Harbor Freight. LOL Yeah, it's bad. But you know what, for what I use it for, it works just fine.

[@albenj401]

When the manufacturer says accurate to 0.xxx”, over how long of a distance? 0.001 over 8’ is better than 0.001 over 6”.

[@angrybeaverwoodworks]

That's very true. Perhaps I should have worded that portion better. I thought I could simplify by stating " The full span of both sides"....but your wording is honestly a more accurate way to talk about that. I even thought about saying the difference in tolerance over 1 inch compared to compounding the tolerance over the distance of 10ft. Similar to the 5 cut method technique. Thanks for commenting

Machinist square / measurement tools are far more accurate than any wood working tools. LOL. Wood working community has been adapting machinist tools such as 1-2-3 blocks. They will never ever need that kind of accuracy for woodworking, but 1-2-3 blocks are dirt cheap for it's insane accuracy.

Love your video, man. I've been woodworking for more than 30 years and I still only consider myself "pretty good." You are absolutely spot-on right when you say the only thing that matters is the ability to cut or drill accurately. I own a number of squares of various types, but honestly the ones I use 99 percent of the time are a six inch machinist square, a six inch Starrett combination square and a tape measure. As for Woodpeckers, I don't believe anything they claim and I don't buy from them any more.

Well stated! I use Empire brand speed squares (6" and 12") and they are extremely accurate after I flattened them on sandpaper glued on a sheet of glass. I've used them for years.

Another (imho) relevant question is How much accuracy do you actually need in woodworking? Angular deviation might be relevant, when it comes to really large squares, almost nobody uses, anyways. Woood itself isn't very accurate. Thermal expansion, wood and air humidity are always factors to consider, when dealing with wood.

Great video and lots of good information to take in. I’ve been a drummer for almost 50 years. I have owned many pro level drum sets and a collection of over 20 snare drums. 3 of the 4 sets I currently own I have BUILT MYSELF! I bought raw drum shells and did all the processes to make a functional drum. I did so, at the time, with all box store tool. Combination squares are very important to the process, and at the time I had only an Irwin square and a few rulers. I dare anyone to find any imperfections on my drums. A couple of years ago I took up woodworking and have built numerous furniture pieces, that’s when my problems began. I still do not own any measuring tools over $60, and I build some decent stuff. It’s all about skill. I still can’t justify $180 for a square, not to say that I won’t treat myself someday. Thanks!

Is cost for Accuracy or Consistency? If the Grizzley squares are DIN 875-1 as they claim then there shouldn't be, as you mentioned, "mixed reviews". Maybe price isn't a reflection of accuracy but the labor for additional quality assurance to ensure consistency? I noticed the same issue of mixed reviews with IGaging as well. Because you received one that is square doesn't mean I will. Of course, it's also possible that it's not a mfg issue but fakes being sold on Amazon.

Well said for your post here. I am a machinist with set-up and high precision experience. It come naturally to me as I am a control freak. That being said EVER situation must be considered individually as to what is needed and what is reasonable or even possible. With precision metalwork one of the more important parts of your tolerance measurements is the temperature of the metals and also the measuring device when your measurements are made. I am leaning more about working with wood but mostly just need time and mistakes till the knowledge and skills are developed. (tooling is not craftsmanship)

[@bwillan]

Woodworkers also forget that the medium they use i.e. wood is imperfect itself. It moves constant with humidity changes. So spending top dollar on precision measure and marking tools is nothing more than a case of 'keeping up with the jones'. Sure you need a good set of machinist spares to set up your tools so that you have a fighting chance of making an accurate just in your imperfect medium.

[@fxp2741]

Accuracy is not about the tool, but the finished product. Assuming one guarantees the other is misleading. It still needs the skill of the craftsman using it. All the increased accuracy is wasted on a fat finger, working with poor lighting or having a bad day. These conditions are more about accuracy than the tool. As the saying goes, sign of a poor craftsman that blames his tools.
