When I was a child (many years ago) girls were not allowed to take the class called "Shop" in high school. That was where one would have learned all the basics of carpentry and tool use. So now at almost 70, I am trying to learn all of what was withheld from me then. Thus, I LOVE that your videos are very basic and cover proper tool use, tricks, safety issues. This one in particular about "squareness" was fantastic precisely because it did not assume a lot of prior knowledge. Thank you and keep it up. I am working my way through all your old videos and look forward to new ones. (How much do we love the internet?!)

Thanks, I knew all about the 3-4-5 triangle, but never thought of using it like that. I also like the trick about nailing a temporary brace once you have it square. Really great content; there are a lot of flashier wood working videos with big sponsors making a lot of money off of them, but yours always feels like I am learning something from someone on an actually job site. The minute I see a new video from you I always watch it. Great job.

Great video, it is good to brush up on things like this! I live in France in an old castle but their build a new building within the castle and to do that the new building is total not square by almost half a foot and believe it or not I have seen buildings with over a full foot out of square and still standing! I am Franco-American building engineer trained and worked state side, I only did this trade state side; this building is a price of art; getting it in here within two older building of over hundred years old I am only half French, and I don't know how it was done!

It may see like wasting time to check for squareness, but as you say, it is a time saver in the long run. Great information for new woodworkers and a timely reminder for us old guys!

[@kennethmiller2333]

I didn't know there was a term for pulling corners, but it's something I did a lot when I was a Damage Control Petty Officer - making sure our quick acting water tight doors were square in their frames. Granted, if they weren't, it was a job for the shipyard, not for us... but the idea still was the same. Rather than a tape, we used two strings and measured them. We also made sure the strings touched in the middle to make sure the two diagonals were in the same plane - meaning the door frame (and door - same idea worked) wasn't warped.

[@garykorzelius5930]

This is definitely an important part of woodworking. My Grandpa was a cabinet maker and before I could build anything I had to build a square box! I finally did after many tries and to a 11 year old that seemed like forever. Tell someone to do this and they think no problem, but believe me it is harder than you think.

I remember high school wood shop teacher who taught us that ,"if you can make a true square " you can build anything correctly! He was so right! One of the first lessons we learned was how to make a perfect square. Our teacher graded us aggressively! Lol! He also taught us how to correctly use a "speed square " and all its features! These two things alone has helped me tremendously throughout my life.

In the 70's I took wood shop. We made large wooden spanking paddles and walked around school swatting other students. We drilled holes in the paddle so it stung more!😮 Nothing square about them.😊

[@number1pappy]

@gwb8445 lol! Yeah, we as students were not allowed to make paddles. However, the shop teacher did make the vice principal a wood paddle with holes in it, and it had "board of education" engraved on it! It sat on a custom-built holder on the wall behind his desk. Corporal punishment was alive and well in the 80s in Texas, where I grew up. They can say what they will about paddling kids in school, but we never had school shootings, and our Schools were not full of disrespectful entitled punks. We even had student driven pickups with rifles in gun racks in the student parking lot. We even had a school sponsored shooting club. With all that, not one negative incident with guns ever. Makes one wonder what went wrong in society nowadays 🤔.

[@waynesligar5948]

I really think you are helping people. I wish i could do videos to help people I'm just not good at talking and now that I'm hurt i can't do much anymore. I loved working in construction and figuring out ways to fix things

[@bobfp910]

Very clear. Nice job. For anyone that is a beginner, remember, opposite sides must MUST be the same length. Repeatability is key. Making multiple boxes requires the use of stop blocks to ensure lengths are the same. On large cases check the backside for square as well. If you don’t have a tape measure, use 2 sticks long enough to cross on inside of box from opposite inside corners. Put face to face. Mark a line across both on edge were they overlap. Use sticks and check the opposite diagonal corners. If square the lines on each edge should line up. If not adjust as needed.

[@dwayne7356]

Building small square boxes took me a long time to learn. Tip one, view the video on saw kerfs. Tip two, use a sharp pencil and learn to hold the pencil and mark the boards the exact same way. Use stops on your saw if you can instead of measuring each board or trim to the final length as a group if you can. Check everything along the way. You would be surprised what happens if your blade is not square to the table. A little 1/32 th gap becomes 1/16th when mated to another piece at times. The smaller and more detailed the project, the less forgiving it seems to me. Sometimes it is better to take the lost instead of trying to make it work.

[@TheHonestCarpenter]

All very good points, Dwayne, especially how mated mis-cuts will compound!

[@n8sot]

Great topic!!!!! This should be discussed more!!!!!!!!!!!!!!!

[@JackKirbyFan]

I smiled seeing that as I helped both my kids with geometry. Ya the 3-4-5 is the Pythagorean triple which are numbers you memorize for different triangles so if you don't want to use the Pythagorean equation you just memorize those numbers. There are a lot of them but multiples of 3-4-5 is the one every geometry student has to endure (I mean enjoy memorizing). Second, those diagonals take advantage of another geometry property. The diagonals are the same in any quadrilateral which all sides are 90 degrees (in other words, rectangles and squares) You can take a deep dive if you want but I thought it was fun to see Geometry applied in a practical way instead of on a chalkboard. Nice job!

[@TheHonestCarpenter]

That’s the explanation I was looking for, Dave 😆

[@phillambert8472]

We're Aussies and bought and live in an old house in France. I swear the builder used the French version of 3-4-5 which is 3.25 - 4.82 - 6.07! 🤣 Everything is out of square and rhomboid! Got to tell you, it made things challenging when we installed square cabinets in the kitchen! Thank goodness for trim mouldings or cornices to hide the gaps. Love your channel and am learning a heap 🙌

[@Bigelite094]

Very important to check your squareness when building on a foundation. You can pull diagonals, be perfect, but a wall can be bowed. Can happen too once you start stacking your roof and a wall bows out. Every once in a while, check to make sure you're still square, true, and plumb.

[@csimet]

Agree. We all know foundations are poured square and plumb! ;) LOL. Some walls of mine are nearly 1" out of plumb over their 7" height. Found that out when I started to frame the concrete walls of my basement. Check everything, more than once, as you go.

[@DJtheLoungeLizard]

I haven't found a square wall in my house yet. And every house that I've seen that is over 20 years old is the same. Wood moves. Dirt settles. Concrete will crack or sag slightly (or more). Today all neighborhoods dig dirt and move it out to level areas. Then, bring in dirt to move the houses back up above the street level. Time goes by and the dirt settles, etc.

[@brucea550]

@@DJtheLoungeLizard You’re confusing dirt and gravel. Dirt, called overburden, is bulldozed off because it’s not good to have under a slab or foundation. Then gravel is brought in to raise the final grade.

[@joshcowart2446]

It’s amazing how many problems an out of square foundation can cause. I’m a plumber. When we’re putting drain lines under a slab we use the forms as a reference. If they aren’t square our measurements may be off. Then we may have pipes coming up halfway outside walls. This can cost lots of money to fix. I don’t do many rough ins these days but when I did, I’d always check the forms for square. If a pipe comes up in the wrong spot, you have to jackhammer and move the pipe or furr out the wall. Both of these things cost time and money. So if I can’t get accurate locations because of forms then I don’t want to be responsible for the plumbing being off.

This is super helpful! I built my first cabinet last year with a sloped garage floor and no workbench. Of course, it was out of square. When I put the face frame on that I had built separately, it had those triangles of blank space you were referring to, only it showed up in an inconsistent reveal along edge of face frame. I have a quarter inch at the top and nothing at the bottom (obviously horribly out of square). It was a learning experience and I hate to scrap the project but I do think it is salvageable at this point so instead of having it continue to take up floor space in my tiny gag rage, I will probably cut it apart and try to reclaim the wood for smaller projects.

[@TheHonestCarpenter]

It’s easy for that to happen on sloped floors, Sarah!

[@vociferonheraldofthewinter2284]

One of my favorite kinds of videos to watch are finish carpenters fixing all of the mistakes of the builders and/or time. Just a slight settling of the foundation can make a HUGE difference when it comes to placing trim. I've seen some old houses with HORRIBLE issues. Try to put in cabinetry that goes almost up to the ceiling when the ceiling is way off kilter. It's an art to make it work. This has always been a lingering question in my mind. When the structure is out of square and out of level do you match the lines of the house to continue the illusion that it's consistent or do you go with plumb, level, and square despite the fact that it'll be glaringly obvious.

[@douglasreid699]

I build flooring cassettes in the UK, usually the drawing has square size on it in millimeters, some if the flooring cassettes are up to 10 or more meters long. But sometimes the timber is wet and has expanded or its not a rectangle or square shape so only one square size, so i use the handy man app which has lots of different calculations in it but one is 3-4-5 rule, you put your dimensions in and click convert and it tells you what it should be. Square it too before putting dwangs or noggins in as easier to do rather than belting it with a sledge hammer to get it square again lol
