This square is the squariest, i mean it. No-picture-s No-picture-s Click the pictures to enlarge them

I went ahead and tested all of my squares for square (I lined them up against a very flat surface, drew a line , flipped them and drew another line; I measured for any difference between the distance between the lines over their length).

The results: surprise, this one actually was square. Over the 7 inches I could not detect any variance. Other squares were longer, other squares were metal, and all but one (which I tossed) was close enough, but only one was actually square.

There are many different reasons why the others were not square, for instance, my pencil line is .02 inches wide. It could be user error, but as I am the user and I managed not to err with the cheap plastic speed square. End result, I use it whenever I can (length and layout permitting).

The reason it doesn’t get 5 stars is because it is plastic and inexpensive and therefore doesn’t feel like 5 stars. No other reason, and it is arbitrary because inexpensive is good and plastic is good because I know it will not hurt a blade if I leave it too close. No clue why I cannot give it 5 starts except it is just a piece of molded plastic. (Maybe I can give the mold 5 stars….)

Edit: When I posted this the first time I got confused between my 12 inch Johnson (yeah, there is a good joke there) Rafter square and the 7 inch Ace. The 7 inch Ace is the squariest. Sorry for any confusion.

As the only purpose for using this inexpensive plastic device is to check for square, and per your own words it functions very well for this single purpose, it should be 5 stars. Sorry to disagree.

If square is square , it should be 5 stars…. That’s what you expected , bought , and paid for : )

I’ve never found a speed square out of square but most of the time I use mine is for construction so it’s not as critical.

I agree with the others, with squares it’s 5 stars or 0. The fact that this one is cheap makes it accessible to many and the fact that it is plastic makes it impervious to corrosion in tough environments. Great buy.

I’d go a step further, the ones that were not square should be called out with 0 stars. Help us avoid buying a mistake.

It’s funny – I just did the same thing this past week with three old (inherited) combination squares, two metal rafter squares and two try squares. I was determined to get any of them out of my shop that weren’t true. My trash bucket ended up with all of them (including the one I most often used!) except one combination square and one of the two try squares.

The remaining combination square, which I had never before used, was all crude and rusty, so I laid it flat on a sheet of sandpaper and cleaned both sides then put a light coat of machine oil on it. It’s now my “go-to” square!

Anyway, I don’t know if the ones I threw away were out-of-square when they were manufactured or if they had been dropped. I’d hate to rate any of them with 0 stars for that reason.

I was being a bit flippant above and i can see how i created some confusion on the ratings For me, 5 stars means perfect in every way. 4 stars is great and you should buy it, 3 is that it does it’s job just fine, nothing special and no major complaints, 2 is it works but I don’t recommend it, 1 star is something to avoid.

With that in mind, a square square should be a 3, this one impressed me by being the only square square I had so I gave it a 4. Maybe I am off and doing your job competently is 5 star territory but that just seems wrong to me.

Also I don’t want to point out the off squares because it could have been something I did or just the way I use the tool. The ledge on the speed square makes registering it against a flat edge near foolproof. While I think I can do the same with an L square I might be off or I could have banged it up a while ago and that is why it is off. I assume that the extra mass keeps the speed square from flexing out of true.

I think this type of square often comes in handy if it’s square. I prefer the ones that are at least made out of metal. I have a Bridgeport and I can make them square if they aren’t. If someone makes a square it should be square don’t you think. Wouldn’t that be the square thing to do?

Here is my two cents as far as ratings go. I believe that a 5 star means something is exceptional. Now a LN plane, for example, is an exceptional tool that is a pleasure to use and such quality does require a certain price (if it was priced at 3 times its current price, it may not justify a 5 star rating). However, a square that is perfectly accurate and inexpensive, though not with the tactile pleasure of the LN plane, can also be an exceptional tool, based on exceptional value.

I’ve got a similar cheap plastic square. I would agree that even though it’s square, and accurately so, it just doesn’t FEEL like a quality square. I know what you mean.

I’ve had this exact square hanging on my wall for years, it’s my go-to square for small jobs. Never let me down. 4 stars, 5 stars, who cares? Great square for not much money…

I would suppose that if it was square, then the 45 angle would have to be exactly 45 as well? Did you look at that?

@ kapanen – I did not test the 45 angle, which would be exactly 45 if the angle is 90 (which this post confirms) and the distance to the corners is the same, and the long side is straight…, which may or may not be the case. As I use a jig for my miters and I don’t rely on the square, I have no real experience on the acuracy of the angle.

@ John – if you want to get a look at my 12 inch Johnson you can always click the link.
Glad I could give you a laugh. No need to point out that it is actually 11 inches.

Have your say...
