I need a dead on square.... I like the versatility of a combo square.... I have looked at Starrett combo square and have never heard a bad review.... They are pricey but u get what u pay for.... Are there any others out there with the same reputation? What do u use?
Ok....so here's where you need to make a decision.....there is NO dead on square.......a starret may be accurate to .0001 degrees square......but its still technically not square....
If your using it for woodworking......you likely don't need anything more accurate than that. I have found that the empire true blue squares are extremely accurate for their price.....This is the one I use.
They're available at Sears and Menards.....and can be had for under 15 bucks. Before spending more....i'd look at one and see if it meets your needs....

Ok I guess I misuse the phrase dead on lol.... But yes you are correct and I would like to get as close as I can.... I mainly want it to set my tools up as accurately as possible... Thanks for the suggestion.... The price of the starrett is why I don't own one
You can get inexpensive engineer's squares, Rockler carries some. These are perfect for machine set ups. Save the combo squares for other work that they are more suited for.
If anyone wants a nice looking rosewood handled square with brass rivets and edge, which is guaranteed to not be square, let me know. Looks pretty. Great for gathering dust. :laughing:
There are many others out there that have the capability to be perfectly square. I have a very old, cheap and not even sure of the brand that will be on 90 degrees every time.
Take a sheet of cardboard with you to the store. Be sure there is one good, solid straight edge. Also have a sharp pencil. If you see a combo square that looks likely give it a "test." The test will not hurt the tool and will tell you if you want to buy that specific item.
Loosen the set screw and reset it a few times just to be sure of repeatability.

PS Also take an engineer drawing/architects 45degree triangle with you to check the angle measurement. They are cheap.
we keep a starret in the drawer for reference. it is dead on enough for woodworking. then we buy cheaper ones and tune them to the starret, and use them everyday. so if we drop one it doesn't hurt as much.
Why do you need a reference square to check against? It is very easy to get an exact check using the subject square. The 45 degree point is mostly easily checked usinf an accurate triangle.
I ordered both the empire 12" square and 12" combo square from amazon for $17 and $10 respectively. I will comment on them in a few days but they look like crazy good value for the money.
Yes plz let us know bob.... I like Tims idea of using the starrett to check the others.... Plus it will be nice if I drop a square it don't make me cry lol
So since I'm brand new to woodworking I can't really give it a 'check' for perfection as I wouldn't have the tools to give measurements within fractions of an inch, however these seem to be well built.
The combo square has a really nice bubble level and the ruler can also come completely out if you unscrew it far enough.
When the knob is at maximum tightness I pulled on the ruler edge and with about 25pds of force and it didn't move from it's place, very sturdy.
I particularly like the speed square and it's thick 3/16''s of solid aluminum. The finish was also a bit nicer and cleaner than the combo square which had a different color and tone to it, although i'm sure that means nothing.
It just has such a nice heavy solid feel to it. I think I will probably use that more often until I figure out better uses for the combo square.
for $27 shipped free for both (I have amzon prime), I'd have to recommend them to anyone. (make sure it says "ships from and sold by amazon.com" so you can avoid third party sellers).
Here's some pics to enjoy.
I have at least 8 squares I use in the shop. They are:
6" try square (old metal Stanley)
8" try square (old metal Stanley)
16" (est.) Craftsman Try square
3" machinist square (for machine setup)
6" combination square (Swanson Loews(?)
12" combination square (older Starrett)
Framing square
Drywall square
Drafting triangles
Of all the combination squares I have used, the Starrett, and a Union, one I had are by far a lot nicer than the others. Both have a hardened rule. They slide a lot smoother than the others.
The 6" combo. square is a handy size to measure set backs etc. 12" can do the same, but the smaller size is easier to handle for jobs it can do. I just found a smaller size one with a 8"(?) rule. It has the smaller head, and rule. Not sure if I will use it much.
I read, that something about the newer Starrett combo squares, being not as good as the older ones.
If I didn't buy tools at estate and yard sales, I wouldn't have the Starrett! Or most of the others!
As far as keeping the Starrett as a standard, and not using it, for actual work. Why have it? I never used a square to check another. Just use the flip it over, method.
Pirate.... Do u have any luck with your Swansen? I have bought 2 from lowes and checked them and the 12" was almost 1/8" off just doing the flip-over!!! The second was still pretty bad.... I only use them for a story stick.....
I have a grand Idea.... If I have a square that is way off but I use it for EVERYTHING from setting tools up to final assembly how would I ever know somthing was off?! Bahahaha
The Swanson combo square is accurate as tested with a flip test. I mainly use it for marking set backs.
My sizes were of a little off on my squares.
6" Swanson was 7"
2, metal try squares are 7" and 9"
small frame combo square is 9"
Machinist square is 4"
Wood/metal Craftsman try square is 18"
I just use them and don't measure them!
If I was just starting out on a budget, I would look for an accurate 12" combo square, first. Bring a 12" x 12" piece of wood with jointed edges, and check any square before buying.

I've got a 6" and a 16" Empire combination square. Both claim to be guaranteed square within 0.0005". I can't test that, since I don't have anything that precise, but within my ability to test they're just about perfect.
To test a square, find a board with a perfectly straight edge: the factory edge of MDF or plywood work well. Extend the square all the way, put the head on the edge of the board, and draw a line out to the end of the rule. Flip it over, and draw another line. If they're parallel, the square is square. If they're not, the error is one half of what you see.
Also: please, PLEASE shrink your photos. This page is practically unreadable for people like me who try to read the site on a small laptop.
I have the 7" Incra that I use only for squaring my machines.
I also have a few other Incra/Woodpecker squares including the T square and I love them all

Ok so I have many different ones as well, the ones I have from homedepot and lowes are ok but not great for real accurate fine woodworking I invested in a starrett and will never go back to anything else once you realize the others are not great or square i can't trust them, I can only use something I know is square and the starrett is dead on square in my humble opinion. I also have an incra t square for working off of stock and incra machinist 6" for checking my machines and the starrett for everything else I love it
