WTB: Stanley framing square

Get me one too. . . ;~)

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

I like the idea of the 18" x 24" square - but I like even better that the LV offering is stainless steel.

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.

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! SH

...

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.

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?
