The opening question suggested machinists squares were part of this query, and while I’ve got wooden try squares up to about 12”, if we’re talking machinists squares, my biggest has a tongue of 36” and it is so heavy that it takes two men and a boy to lift, It has it’s own protective box, probably not original, Similar to this, but made by browne and sharp http://www.starrett.com/metrology/metrology-products/precision- measuring-tools/squares/Solid-Squares#currentPage=1&displayMode=grid&itemsPerPag e=24&sortBy=wp/asc">http://www.starrett.com/metrology/metrology-products /precision-measuring-tools/squares/Solid- Squares#currentPage=1&displayMode=grid&itemsPerPage=24&sortBy=wp/asc It is so large that it can check rafter squares to ensure inside edges are square with outside edges, and of course inside/outside edge squareness. with a high degree of precision, but when I want portability, I just use the 24” tongue B&S smachinists square. And now I can drill hang holes in them with my MF 666 devils drill (running and ducking!) There are ever so many reasons as to why a try square, or for that matter a square of any type has been abused, that even if the stock looks pretty with it’s wood and brass, that it has to be tested to prove it’s squareness Eric in cowtown |

I could swear that I've seen a photo, old-time work yard, with a man standing next to his try square. It's taller than he is. I can even see using one that size, maybe in shipbuilding. But, since no-one has mentioned such a size, I suppose I must be misremembering a similar tool, or maybe my mind is making it up wholesale. Or maybe it was a tall-tale postcard photo, like the ones of cobs of Iowa corn being carried in railroad log cars.... Tom Conroy |

I would think a square that size wouldn't be for checking squareness of a part, per se, but might be for alignment of parts. But, then again, I see new things every day... *** This message was sent from a convenience email service, and the reply address(es) may not match the originating address |
