I bought a Johnson combination square from Home Depot earlier this year for a few bucks. When I took it home and tested it (by drawing a line perpendicular to the edge of a board, flipping the square around, and drawing another line), I discovered that it was horribly out of “square”; the ends of the two 12” lines that I drew across the board were almost 1/4” apart! I returned the square to HD and discovered that the other squares of the same model were similarly out of whack (sadly, a few days later I observed that the square I had returned had been put right back on the display, even though I explained how awful it was).

Later I bought a Craftsman square at Sears. This one tested out very well; the lines I drew perpendicular to the edge of the board were exactly parallel, at least as far as my eye could tell.

Since then, I’ve read a lot of comments by LJ forum members and by various web bloggers extolling the virtues of Starrett combination squares. My question is this: if the square I already own makes perpendicular lines with the same apparent evel of accuracy as a square that costs five times as much, do I really need a pricier square? Sure, it would be nice to have one, but what advantage does a Starrett square provide that a Craftsman does not?

Also, if I decide to drink the Kool-Aid and buy a Starrett, how good are the used squares on eBay? Does a Starrett square tend to stay true over decades of use, or do they ever get out of alignment, either with use or perhaps being dropped onto a concrete floor?

You don’t need a Starrett.

A cheap square can be made accurate enough for woodworking by
filing the alignment tabs in the casting until it makes parallel lines
when flipped.

Eventually, if you keep your eyes open, you’ll find your Starrett at
a garage sale for a couple of dollars. I’ve found a few.

I bought an expensive Starrett and compared it to my cheap ones. The cheap ones were just as accurate but the Starrett just feels really nice in your hand. Of course, vintage try squares feel even better but mine were WAY off.

Starrett is top quality stuff, and if your budget permits, by all means go for it.

But Loren is right … I use Empire Level ( http://www.empirelevel.com/ ) combination squares that I bought several years ago at Menards. The ones in my shop (I have 5) are dead-on, and cost a fraction of what my neighbor paid for his Starrett.

If I owned a Starrett and knocked it off the bench, I think I’d go apoplectic over the idea of damaging such a fine tool. With the Empire squares … not so much.

I reviewed a starrett square as compared to an Empire (pro) square from HD. both were just as square!

the benefit of the starrett is that the machining is much better, and the operation is much smoother and easier to set at the correct values without fumbling around with it too much, but it is not any more square for sure.

that said, I replaced both my Empire squares with starrett equivalent because they were smother and easier to use but only did so when I found them at reasonable prices (estate sales). For my use and budget I would not buy them new at the store although if your work depends on it you may consider that a good investment.

Accuracy depends on how many times it was dropped.

My thoughts?
Stay away from Sears.
I boiught a Starret at an old shop for nuthin’ (I think $10.00). It was a 4”, and I use it all the time for needed layout.

I had a similar experience with a Johnson square. And I also found Empire to be a superior product in comparison. When I recently compared Craftsman and Empire, I found they looked pretty much identical. I suspect they were manufactured on the same line.

I do like the satin finish that Mitutoyo, Brown/Sharp, and Starrett offer on their rules. I recently bought a lightly used Starrett combination square head, but did not get a rule along with it. Paid $10 and can get a rule for $20-30. I figure its a good way to get into a Starrett at a realistic price.

I purchased a Starrett combination square on e-bay for a relatively modest price (don’t really remember but I know it was a low price). I’m delighted with it.

I can’t justify the price of a new Starrett, but if you find one on e-bay at a good price, give it a try.

Don’t be afraid of doing some clean-up. The best bargains on e-bay just need a little cleaning.

If the tool you have does the job you need it to then it really comes down to what you want, not what you need. I do have to admit though that if you asked me what was my “favorite” tool in the shop, it would be my 12” Starrett Combination Square. It just makes me happy.

Maybe the board you used is not square.

But you can send the starret square back to the factory to be re- aligned again for free.

I have bought many used Starrett squares, scribes, and other machinist’s tools that can be used for woodworking, from a guy at a local flea market. He sells new machinist tools and buys up used tools from guys that retire and resells them at the flea market. If you look for deals, they are out there. I’d rather buy quality used Starrett or Lufkin tools that I know will outlast me if I take care of them. It saves a lot of money.

I have a Starrett #4 combination square set that I have had for over 30 years. It is still accurate and the easiest to use of the many combi squares I presently use. I bought one from Sears a few years ago and couldn’t get rid of it fast enough. It was horrible. I also use a Sowa and a Mitutoyo but the one I always reach for first is my old Starrett.
Another I got talked into buying is a Japanese one called Asimeto. Engineered in europe and manufactured in Japan but very nice as well.
I love tools and make my living with them and find you cant go wrong with Starrett, Brown. And Sharpe or any of the top line names. They may cost more but last a lifetime and you can hand them down and the name still makes them appreciated.
Cheers

I am very disappointed with the 12 and 6” combo squares out there today, mainly Johnson and Empire.

the tightening screw shaft eventually looses it’s ability to hold the ruler and can be pulled out of square. I bought one recently and the notch that holds the ruler actually broke off… no, I didn’t over tighten it.

I’ve been surfing E bay for months and see good deals on Starrett tools, including the box. I know they’re more expensive but – look at what you’re comparing it to. Something that is designed based on a perceived price point.

I also have some vintage Craftsman HQ squares that are really nice. They did make a few good industrial grade tools back in the day. Good prices on E bay too, considering everyone wants the Starrett.

My absolute favorite square is a little 6” rectangular shaped Starrett square I bought new from Woodcraft.

There is something about a Starrett when you hold it in your hand that makes you smile and say,

” My grand kids will own this some day.”

A used Starrett might be perfectly accurate, if it has been taken care of. The nicest square in my shop is probably my Starrett die makers square. I have a drawer full of squares, however, all sorts of brands and types, old and new. As a matter of fact I bought some of the oldest ones new, but that’s another story. I have never found any problem with the Empire and, as someone already mentioned, the present Craftsman squares are the same as the Empire. The square I use the most in my workshop is a six inch,Swanson type, rafter square made by empire. it is quite accurate and I appreciate the simplicity of a triangle square. The tri-square I use the most is a Stanley, the combination square I use the most is an old Lufkin. I have a sixteen inch Swanson combination square that I have been quite happy with. The square I have owned the longest is a six inch Great Neck combination square that I got new in 1979. It has been a great tool. If one can have one square, the combination square is probably the best choice. All that matters is that your square is square.

If they are square that is a great start. I have a new Starrett square and a vintage one as well, along with some other newer makers. While the new ones are somewhat expensive, they do work well and should last a very long time. Plus the vintage Starrett stuff is just cool to me, in the same way as vintage Stanley Bedrocks. I just happen to like them. I look through the ebay listings regularly to pick off any good values on the old Starrett stuff.
