## Description

Swanson Tool S0107 12-Inch Speed Square Layout Tool with Blue Book : desertcart.co.uk: DIY & Tools

Review: Fast delivery and good quality - Arrive vey quick wasn't expecting them until after Christmas on delivery date as they were coming from US very heavy weight son is hapoy
Review: Unbeatable for framing work - This is not a replacement for an adjustable combination square and is not suitable for fine work, but for its intended use in framing work it is brilliant. The pencil notches for marking lines parallel to the edge of a board are very useful when ripping wood and the protractor feature is surprisingly usable (though again, not really for marking off 3.25 degrees!) The wide base makes this convenient for checking joints for plumb as it will stand on its own quite securely; this base also makes a really solid rest for when you want to mark a cutting line at 90 degrees - it hooks over the edge of a standard CLS 2x X timber perfectly and gives a far more positive result than a standard combination square (the full length of the side of the square being in contact with the timber really helps here too.) I have not yet used the square for the purpose for which I bought it (laying out rafters for my current project) but hope to do so soon - the accompanying "blue book" seems fairly comprehensive and I'm confident this square will make my life a lot easier when the time comes. Overall the square is well made from nice thick metal and very nicely finished. My only criticism would be that the black paint applied to the markings wasn't particularly thorough; as the markings themselves are deeply recessed into the metal there is no issue in practice. Edit: I have since used it to make rafters and very much more and it was excellent. Once you've figured out the desired roof pitch it's so simple to get every cut at the right angle - not just for rafters but things like barge boards, sheathing, lining, interior trim etc. Worth every penny.

- Heavy gauge aluminum alloy with matte finish to prevent glare
- 1/4 in. and 1/2 in. spaced notches to facilitate scribing lines

## Questions & Answers

**Q: Where is this square made**
A: Dont know but i personally think a framing square with stair guages works better, its kind of cheap quality

**Q: I am not a pro, I just want to do some wood working around the house here and there. Will this tool benefit me more than the 7inch version?**
A: I work as a carpenter and i have both the 7inch and a 12inch version.I carry The 7inch speed square with me all the time and use it a lot, the 12inch sqaure i keep in the toolbox because it's size makes it unpractical to carry with me and to be honest I rarly take it out and use it, maybe once or twice a month.So as for using at home I would go for the 7inch.If you occasionally need to make a longer marking then 7inch you can lay a straight board along the 90 degree side, then remove the square and make your marking. That works really well:)Hope this was useful for you!/Claes

**Q: I just bought the 12" speed square, The slot that is supposed to hold the rise portion is way to large for the supplied 1/4" bolt?  anyone else?**
A: I just bought the same exact item from two different big box retailers.  I bought and returned the first purchase because I assumed that the manufacturer had issued a recall on the item and the retailer had neglected to pull the existing stock from shelves.  Because I was beginning a critical new stair job and I had chipped the pivot point on the 15 year old 12" speed square that I already owned, I bought another one from the second retailer.  The product was defective from both retailers....and this is 10 months after your Sept. 2014 post.....apparently the problem has not been corrected by the manufacturer.

**Q: “first time to buy and use the speed square. should i start off with 6in or the 12in? Beside their size, what other difference do they have”**
A: I would suggest the 7" speed square. If you are going to be cutting a lot of 2x12's then the 12" would be handy in addition to the 7''. The 12" square comes with a layout bar for cutting stairs.

### ⭐⭐⭐⭐⭐ Truly brilliant...!
*by P***S on 5 March 2022*

I've been a carpenter in UK for over 40 years and didn't know that 'speed squares' existed until seeing one being explained on a YouTube video last year. Just goes to show how long I've had my head in the sand believing that combination and try squares were the answer to everything. Firstly, I want to point out that these things are designed for speed and the markings are big to be visible with ease, which I suppose could render them 'good enough' rather than pinpoint accurate (though they are accurate). If anything, I would describe them as being the Swiss Army Knife of carpentry - especially when you get the 7" and 12" twin set, which even comes with a little book of tables for calculating roof and stair angles. The metal is thick and solid. There are loads of markings and scales for measuring lengths and angles. They can be used as horizontal and vertical levels. You can use them as guides for a circular saw. There are pencil notches to drag out parallel lines. I mean, they do it all, apart from cut the wood for you. As you may have guessed, they have become integral - indispensable - tools in my kit. They save so much time that it would be inefficient not to use them. I still use a combi square for the occasional instances that they are required (measuring and marking accurate depths and so on) but it is no longer my primary 'go to' square. All in all, an excellent product at a great price.
