Not just any old Satanley square, though. Here's a copy of a WTB request I
sent to the oldtools forum. So far, no bites, but check your squares. If
you have one and want to sell it, let me know.
"This critter may be extremely rare, but if you have one for sale, I'd be
interested if the price was right. I'm looking for a Stanley R100 steel
framing square that has an 18" long short leg instead of the traditional 16"
short leg. I saw one yesterday in a set of tools owned by a local timber
framer. His wasn't for sale, but he pointed it out to me and asked me if I'd
ever seen them. Nope, but now I want one."
It makes them pretty useful, too. 18" side, 24" side, makes 30" across the
hypotenuse of the triangle. 3-4-5. Why this wasn't done with all squares,
I'll never know.

am I the only guy in the world who hooks the *inside* edge of a square
against the edge of sumpin and scribes a line on the *outside* edge of
the other leg?

It's funny (to me at least) that you bring up the 3,4,5, theorem. We throw
a big xmas party every year for our employees. Part of the entertainment
is gambling. We set up a 4,5,6 table for everyone to play. It never fails
(I should do a study) but when the guys are laying out framing or concrete,
or whatever, they frequently use the 3,4,5 theorem. Of course, the month
immediately following the party, that 3,4,5 layout turns into the 4,5,6
layout. Trust me, it doesn't work!

note though that they only claim accuracy ground on (iirc) the inside
edge. whassup with that?

From the online product page: " The angular accuracy is ±0.001
radian (1/17°) for the outside edge."
I would guess that it's a cost trade-off. I hadn't really given
it much thought - but, interestingly, I've only ever /used/ the
outside edge. I bought the LV square for the sole purpose of
truing the gantry on my ShopBot; and for that I only use the
outside. I suspect it may be the most "coddled" carpenter's
square in a thousand mile radius (-:
For squaring (or checking for squareness) stuff that I build in
wood I use either a similarly coddled aluminum drywall square
(looks a lot like a 4' T-square and whether by careful
manufacturing or accident, seems to be 90.000° - from Mayes) or a
Starrett combo with a 24" blade.

To guarantee the same accuracy on the outside edge as on the inside
edge you'd have to maintain a much better accuracy on parallelism
of the inside edge to the outside edge. Like about an order of
magnitude better.
Otherwise, as you true one, you'd 'untrue' the other.

Why is this useful ? Surely the point of a square is that it's, well
"square" anyway, without also needing to be a 3:4:5 triangle.

Andy...
When I bought my framing square from Lee Valley, I also bought a
56 page pamphlet titled "How to Use The Steel Square". Believe it
or not, the framing square can be used as a calculator for
solving an interesting range of math/goemetry problems.
I like the idea of the 18" x 24" square - but I like even better
that the LV offering is stainless steel.
