Common rafter and hip/valley rafter scales permit one-number references for all cuts. The square is merely rotated to the proper roof pitch value on either scale to assure the correct angle cut. The slot along the scales will accommodate an adjustable locking pin for repetitive cuts using any 1/4-inch bolt and nut. Comes with a handy, 62-page pocket sized booklet that provides vital instructions, reference diagrams, and tables for the construction of roofs and stairs.

First Timer w/Rafters and "Birdsmouth."
4 Stars
First Timer w/Rafters and "Birdsmouth."
I'm always trying to increase my knowledge of building and carpentry and recently decided to incorporate a rafter (with bird'smouth) design into my window awning project. The Swanson square was perfect for the job and with the book it came with I was able to learn the "One-Number" rule that makes it real simple to build your roof rafters. I'd advise all first timers to do it on a smaller project--such as dog house or small shed--before a home's roof. I'm not a natural numbers guy so only read the book in a few parts, watched a quick video on the Swanson square and then went to work.I went through three sets of 2x4 rafters templates until I got the angle just right for the rafter to sit up against the ledger against the wall and the birdsmouth to land on the lower 'sill plate' that would support the window awning. I think my "ONE" number for pitch was 9 (I was using degrees{36}) and from that number you can essentially build a real roof. It came out great and from this one project I''m pretty sure I can build a real roof for any structure I design at this point. If you know your 'one' number prior to building a new project but we didn't because of other concerns such as making the awning tall enough for my clients to walk under while slope had to be steep enough to provide sufficient shade to window. As a result, my assistant and I had to test angle cuts (and then hold them up against the framing structure) until we got the approximation of 36 degree-which makes all the rafters plumb cuts. Then using the square we got the pitch of 9. More importantly, you can use a simple formula to find the distance for your birdsmouth (where your 'seat' and 'heel' cuts meet the outer edge of your bulding/sill plate). Prior to this project I only used my squares for 90degree cuts. Now, it's opened up a whole world of building possibilities. Thanks for the book, Swanson.

5.0 out of 5 stars La vera "Speed Square"
Reviewed in Italy on October 20, 2020
Davvero fantastica la famosa "Speed Square" della Swanson. Realizzata in alluminio, robusta e leggera. Ho preferito la versione originale da 7 pollici perché la versione in metrico decimale è più grande e leggermente diversa. Per quanto mi riguarda il fatto che sia in pollici non mi crea nessun problema. Non è una squadra per lavori di fino ma da carpenteria (utilizzata principalmente per la costruzione di tetti). come squadra di precisione utilizzo una combinata Starrett. Comodissima per mettere in quadro due pezzi, come guida per fare un taglio a 90° con la sega circolare a mano, per tenere fermo e bene in quadro un pezzo da tagliare con la troncatrice, per tracciare linee parallele lungo un'asse o una tavola... Con un filo a piombo si può anche usare come livella (appoggiando il lato lungo sul piano e facendo passare il filo sul "pivot point", il filo deve passare sulla linea dei 45°, e si è sicuri che il piano è livellato). Nella confezione è presente un libretto in inglese con tutte le spiegazioni tecniche per i suoi svariati utilizzi. Immancabile nel corredo di falegnami, carpentieri o feticisti dell'utensile :D
