I'm on my third attempt at a straight 8' saw guide. Resorted to U-shaped aluminum on a factory edge of bb ply this go-round and STILL not there. Slight bow in it after assembly. Sigh. I might start chopping up angle iron from a bed frame I found. Got any videos on making due? If I get one thing straight, all else will follow.

Another tip is that when adjusting your squares if you make it a habit to hold nearest to the blade during the slide motion they'll stay square longer, further away from the blade technically should cause a microscopic amount of racking tension combined with the sliding motion and rub a tiny bit harder on one adjustment post than the other, a trick I use on my Empire square that I have to tune once a year, maybe I wouldn't have to be as anal if I had an expensive one.

[@maxwellyedor7610]

I like Harbor Freight squares, perfect for checking 89 and 91ish degree angles, and the built in bubble level is perfect for making sure you have some slope in a concrete form for proper drainage.

[@Ferndalien]

Fom the rare few times I've had to do a little bit of concrete patchwork around the home, it seems it would be brutal on many measuring tools, so good enough yet cheap to replace is the way to.

You get a ton of views too so I'm sure you are helping them suckers sell, you should try to get an affiliate link too. Taylor Tools sells on eBay and their own site, and if you look at the item revision log on eBay you can see when the stock is updated when something sells on TayTools.com (presumably). Virtually every blem tool started selling like hotcakes on March the 1st, the date of this video.

Your presentation and delivery are comprehensive to the point I am actually learning enough to understand how all this stuff works. Thanks for lessons well done!

[@hauptmanndosman]

Really wish I saw this before today. I just bought an empire 6" combo. When I got home from work I did some playing around with it and my veritas layout square. Over 4.75" it is out maybe 1/32 of an inch. That is 0.00657. For most of my needs that is sufficient. There is also a slight high spot in the middle of the one side, that I could hone out with my wet stones, but again, it is sufficient. Especially since I will be using this to mostly marking out screw locations near the edges/ends of boards. I am definitely going to go get a BLEM one from the link though. PS from my experience the Empire stuff is not so much for fine woodworking, but more for general carpentry, ie building a deck or a house. I have seen precision doing that to the nearest 1/4" or if you are lucky 1/8"

[@bdm1000]

Great video. Before watching this, I thought I needed an Igaging or Woodpeckers little square, setup blocks, and all these other fancy do-dads, but by using a combination square for all these things and more, it's already paid for itself. Thank you for the first person to give an honest and informed opinion about squares. So far I've watched a half dozen videos that mostly wasted my time.

[@sparky1044]

Hahaha, I wish I could show you what my dad's old combo square looks like...perfect for drawing waves in a uniform manner.

[@missingsock18]

I just purchased a PEC blem combo square and folks, and the difference between this tool and the Stanley/Sears/Irwin models is night and day. The head itself weighs more than an entire Sears 16" stainless steel combo square. There is absolutely no slop in the fit between the blade and head. The markings are super clear and the edges are tack sharp. What you're paying for: 1) better steel 2) extra labor to mill the parts to higher tolerances 3) higher quality control, resulting in a single tool that can serve many different purposes, as Mr. Katz-Moses so elegantly explains. Dude, thank you for helping a brother out! I love your videos and can tell a ton of work went into editing them---you get to the point quickly and clearly and we're lucky to have someone who is not only a talented woodworker but also a teacher (MOST of us cannot teach, contrary to popular belief).

I have a 2 double squares from PEC and Starret (6” and 4”) and a 12” Starret combination square. I use the Starret for machine setups and the double squares for layout and joinery. Good ones help with precision and I don’t regret spending the money on good squares.

[@tomm5256]

I inherited a book called Steel Square Pocket Book from my grandfather. I think it was a his textbook from school. It was from 1903 and has tricks (I call them tricks cuz I’m ignorant) for marking out all kinds of stuff really fast. It’s mind blowing all that you can do. A lot of it is based on the ratios of rise/run of the square.

Man I could kiss you! The info on blem squares is an absolute game changer. I have only been woodworking for a couple of years now, and as of late, I have become obsessed with the facts that cheap squares hurt more than help. I have recently purchased a 6 inch PEC square for full price, and it has honestly become one of my most prized possessions in my shop. Since getting it, I have been determined to purchase a 6 and 12 combo square from PEC, but couldn't bring myself to spend 90 bucks on a 6 inch combo square. I just purchased the 6 inch double blem square by PEC from the site in your link. 35 dollars to my door. That's with shipping and handling. It is one in the morning and I was crouched in my bedroom using the light from my computer to enter my card information because I absolutely don't want to waste another second without such a great tool at an amazing price. This might have been the most helpful video of my woodworking career yet, because it makes these high precision tools, which help me be a better woodworker, much more accessible. Thank you for sharing this link. If you can get a kickback from Taylor Tools from me ordering with your code or something, please let me know because I will be ordering the 12 inch combo very soon. Thank you for sharing this awesome secret!

What you are calling a t-square is actually called a double square.

I have at _least_ a dozen assorted squares including three 12 inch combination sets (a Starrett, a Mitutoyo and a cheap Chinese) two small combination squares (an Empire which is surprisingly good for what I paid for it, and a cheap one) plus three engineers squares, a precision square (which I bought from Wish and wished I hadn't because it is shite) various framing squares, a big woodworking square, four magnetic welding squares, pairs of 1-2-3 and 25-50-75 blocks which count as squares and are incredibly useful, and I must have forgotten about others like the T-square and plastic tech drawing square. These were collected over 40 years as a toolmaker, and 15 years of retirement now loving working with wood. I loved the tip about using the grove in the combination square as a pencil notch. That was genius and something you wonder how I never thought of it years ago. A tip I would like to seen is how not to lose the retain nut from combination sets. In my case its from the protractor, and thinking about it, I could easily make one, but I am restricted to my home shop during lockdown - which our PM has just told us is now likely to extend well beyond the initial four weeks. We can't even order in tools as they are not delivering that sort of thing - I must have half a dozen items stuck at the border with absolutely no idea when they will be released. It could be months! Are you allowed to mail out your stuff right now, and if yes, does that include international (New Zealand in my case)? Anyway Jonathan... Thanks for keeping us entertained and informed.

I made it but not so proud of it since the 4 leg not square yet paralel to each other.

[@leehaelters6182]

At 7:15, you are right that the engine divisions can be used for extremely accurate layout, but it is kind of a goofy way that you do it. Opens you up to error and excessive wear of the divisions, or dulling of your knife on a hardened rule. Instead, stand the rule on edge and guide the scribe, or the unsharpened back edge of your knife, down the division to the surface. This eliminates what is sometimes called parallax error.

[@beckermen]

Thanks KM! I just found the great accuracy of using a marking knife along with a good square!

Honestly, when I began live as a mechanical designer, first thing I bought myself was a set of squares, a set of micrometers, steel scales and was talked out of buying a dial caliper by the guy at the store. He told me, get a Vernier Caliper and you will have it all your life, because no one will steal it. He was totally right, and once you get use to using it it's no slower to use than a dial caliper. I have actually walked off and left my calipers out on a machine, then went back and they were still there and they had been moved. picked up, looked at and put back down. Over the years guys have walked over and looked them over and asked why I haven't gotten a "good set" of calipers. I'd tell them, "Those ARE great calipers". I still have them.

@@OvertravelX Back in my machinist and mechanical engineer life I started with Mitutoyo dial calipers and mics.

I later picked up a set of 6" Etalon dial calipers out of curiosity, I like them alot too.

[@jimapaschis]

You voiced down aluminum squares as a carpenter's 24 X16. But they out there. They may not be square but can be adjusted using a hammer and cold chisel. If the internal is acute (less than 90) hammer the interior with the chisel a bit and the angle will open. If the interior angle is (greater than 90) hammer the exterior corner with the chisel and it will begin to approach 90. Of course a reliable square template is need and may be factory cut sheet of plywood.

[@joshmckinney3254]

My personal advice: buy whatever square you can afford; they are a must. If you can afford one of those nice squares, by all means, get one. But for people like me (just out of college, newly wed, living in a 1 bedroom apartment) a cheap combo square is better than no square. I have been trying to wood work as much as I can and I am amazed at how much better I have gotten with the aid of an Ace Hardware combo square. I thought I was doing okay with a small measuring tape and pair of digital calipers, but I was sorely mistaken.

[@mikesmicroshop4385]

While the grove in the beam of an adjustable square can be used to mark a line that way,, make no mistake about the fact that you can be off your intended mark if you do it that way! If your marking point is able to go under the blade past the end edge it will be under marked as easily as you can over mark by placing your marking pencil or pen to far from the edge! That grove is there so that the knurled knob in the head of the square can tighten the clamp inside the head down on the blade when setting the square and not for the purpose of making a mark.

What do you need a double square? Can’t you just use a small combination square? I use a 4 and 6 inch machinist and 6 and 12 inch combination. Isn’t that enough? I would like to get the compass though. BTW, I say again, I love your videos. Keep making them. Thanks.

Thanks bud. Everyone has different work flow. I like the t-squares as opposed to the machinist squares because they do the same thing but also so much more.

Just ordered a 4 piece kit and a 4” from Taylor. Thanks!

How for off was the protractor? Mine is off 3 degrees! Precision they say?

Nice overview, I learned a few things.
