Starrett 505A-7 ProSite Protractor



Quality control issues
Sturdy, nicely made tool, very easy to use: Match the arms to the corner, read the scale, set the saw, cut the trim. However, on the first one I received the scales did not match. For example, on a (maybe) square corner the single cut scale would read 0 and the miter scale would read 46. Same thing on inside or outside corners whatever the angle. So which scale is correct? Only way to find out is to cut and then recut the board. The purpose of this tool is to find and measure SMALL inaccuracies. If you can't trust the scales then it is simply an expensive angle take off tool and actualy less useful than a regular T bevel. I returned it to Amazon and very quickly received a replacement - which was no different. Not ready to give up I called Starrett and spoke with a very helpful and knowledgeable guy named John in tech support. He indicatd that the company is aware of the problem and is working to fix it. He suggested I return the tool to them and they would hand pick an...

Should Be A Required Piece Of Equipment
This is the smaller version of the 12-inch protractor, and is a tool more suited to my apron pocket, where it resides with their 6-inch T-square. It is as precise a tool as you could ask for, easy to use one handed, and invaluable for checking the alignment of tools before you make a mistake. It's the perfect protractor for in the shop, smaller work, where the 12-inch model's size makes it a bit unwieldy. It won't cut wood for you, but it will help you make sure that what you want is what you get.

5 star quality, 4 star price.
Look, let's be blunt. No matter how good your hotshot framing and drywall crews are, even new construction is never square. And in old houses, it just gets worse. And this doesn't even take into account irregular angled walls that are anyone's guess.

Now I know the rest of you all payed attention in 8th grade geometry, but for those of us who don't like mulling over math problems on the job site, the Sarrette is as good as it gets. Read the single cut angle off one side. Read the miter cut off the other.

And the tool can (and should) be used to set your miter saw to the exact angle you need. Read it off the wall, set the blade using the tool, cut. Perfect.

Oh, the pain I could have saved myself if only I'd bought one of these earlier. Cutting scrap test pieces and banging my head against the wall wondering how I'd gotten it wrong again.

Basically, if you do a lot of finish carpentry, having one of these will save you a lot of time and...
