I take it then by the no response Doug, that square really isn't square if its a Starrett. But I won't dog you on this as you did me over the word "must" since I knew what your intent was and I don't have to *prove* I was right...;-)

Reminds me of an old one:
In this world, there are often two sides to an issue. One is right, the other is wrong. It can be difficult to determine which is which, and we can debate it for some time. In the interest of brevity, I have a simple solution to determine who is right, and who is wrong. I'll take the former, you take the latter. Case is settled.

Not a case of "no response", Bob -- I haven't been near the computer for 8 or
9 hours. See my other post in this thread.-- Regards, Doug Miller (alphageek-at-milmac-dot-com)

Angle of error = arctangent ( 0.002 / 12 ) = 0.00955 degrees
So it's within less than 1/100 degree of perfectly square.

well, I'm glad you included the Incra, as that's MY "guaranteed square". 'twas a X-mas gift that I ask for when folks asked for ideas. I got the 5" one so that I can place it next to the BS blade to set the table perpendicular. Not that that's the only thing I use it for, of course.

As far as I can tell, there isn't much difference in accuracy between Incra and Starrett; they're both as close to dead-on perfect as I need them to be. I found the Starrett combination square preferable because (a) I needed an accurate, easy-to-read rule as well, (b) it combines accurate 90 and 45 degree angles in one tool, and (c) it's cheaper than buying an Incra 90 *and* an Incra 45 *and* a rule.

Doug, I've got one of the worlds LEAST accurate combo squares; a Stanley. I should probably toss it into the recycle bin. I sure as heck won't use it on a WW project. It's a LITTLE less accurate than
0.00955 degrees! :)dave

You could have done the same job with a pair of pliers and a bottle of whiskey. See how much money you could have saved? :)

That would have been cheaper, but not less painful.

Geez, if it isn't square, make it so. I've filed a bit on my "Japanese" combination square so it matches, and ditto some lumps on speedsquares. You talk all the time about fettling planes, why shy from squares?
The first square I can remember, an old metal Stanley from dad's 50's shop is now square, and in use at my house. I have a feeling dad never used it much after the many drops it suffered from me.

Well ... close enough. My marking knife would make more of a deviation than that over the 12" length.

Au contraire there Dave. There was an article last year in one of the trades where the Stanley was actually rated very highly - if it's the yellow bodied one. The article also showed how to true and tighten them up. I was surprised at how accurate they said some of the lower cost versions were.

Yeah, it prolly was more like 7. Couldn't be helped though: time in the shop, then go pick up the kids from school, run one of them over to baseball practice, fix supper, eat supper, prayer service at church with SWMBO, pick up kid from baseball practice... time flies.
