Starrett tools feature unerring American-made precision and durability. Their century-old dedication to producing only the highest quality tools has earned them the well-deserved title of "the world's greatest toolmakers". This is the tool professionals rely on for accuracy. This combination square features a machine divided, tempered steel rule. A hardened scriber and spirit level are included in the 12" model. It is marked with 4R graduations which comprise, 1/64, 1/32, 1/16, and 1/8 inch graduations.
I never knew Starrett invented the combo square. Nice tidbit, thanks!
Though some earlier 19th century tools were called combination squares, the modern combination square was invented in the late 1870s by American inventor Laroy S. Starrett, and patented in 1879. In 1880 he founded the L. S. Starrett Company in Athol, Massachusetts, United States. The tool was originally designed for machinists, but over time became commonly used in other trades, such as woodworking.
A fine, accurate tool and a delight to work with. I have several and use them frequently.
Also is a level and handy for short spans. Ruler detaches if you need it by it's self. The pin is a scribing tool. Good for tile or metal. I love this tool for those times a regular square is just big and awkward.
One of the most used tools I own and I have a lot of tools! Starrett the last word. Thank you.
In 2022 it feels so weird not to see saw stop, refreshing haha
One of my most used machinist tools.
Dear Master, I have not learned that much in such a short time, thanks for teaching me !!
I think a way to test the combination square would be useful, since every measurement, test and cuts done with inaccurate combination square will remain inaccurate. Also it would help to find a way to fix the combination square if it's out of square. The fine adjustments one should do to any tool, either hand or power, is a must.
There are simple ways to do this. Use Google. :-)
Cesar, as a hobbyist I do far more metal machining than woodworking so I look at tools and the setups shown in this video from that perspective and that's usually well past what any woodworker would need. But simply saying you want to find a way to test the tool or fixing inaccuracy's if there found doesn't help. Just how accurate do you want it? And how much would you be willing to spend to check and adjust it? A Starrett combination square could be sent back to them for checking and even adjustment. Any company that does machinist tool calibration can at least check the tool. And any company that has a CMM (Coordinate Measuring Machine) for checking there machined parts who are willing to take in outside work could check it to a few millionths with a top quality machine.
You can get fairly close checks by drawing a line on a piece of ply and using the factory edge, then flip the square around and draw a line parallel and maybe a 1/16th away from the first. Any inaccuracy will show double what it is on the square. Do a search here on YT for The Tool and Die Guy then search for his video titled squareness checking. But it all depends on just what equipment you already have or are willing to buy and again what your accuracy requirements are. But a good cheap method is checking with a diesel truck repair company and see if they have any used but good condition wrist pins from the largest engine you can find. They work much like a cylindrical square (google that term) and are precision ground to high accuracy limits. I've got a couple of the proper cylindrical squares but I'd doubt you'd be willing to pay what they cost just to check a few tools once in awhile.
As to adjusting something like a good Starrett or other combination square. You won't have the specialty machine tools to do a proper job. You'd need to return it to the manufacturer. Most woodworkers don't fully understand just how delicate precision measuring tools really are if you want dependable long term accuracy. Treat, store, and use them like there an extremely expensive mechanical watch and they'll be fine. Drop them just once on the floor and you can bet there accuracy will be damaged. And I know one thing, despite what's shown on this video I'd never rest even a hardened square on a router bit or saw blade. Make a test cut in scrap and check that. My apology's for the length of this, but you did ask.
Very good
Old man ,classical music , useful video😍😍😍
hi, what you are saying is the Starrett square is very very very precise? Chris
Thank you for these tips. You have an excellent voice and manner of speaking for demonstrating ideas. Oh and the music is fine. Nice choice as it doesn't from the points you were making. :>)
If you put the pencil on the mark THEN bring the square up to it it will work better
Or use a marking knife.
@@Bogie3855 all of the above
I am going to have to get one. Thank you.
They are NICE to have!
very useful tips. thank you, sir!
Muy buen video ahora ya sé cómo se utilizan 😀
thank you very much sir ! now i know how to use it
Pretty much good points info that I learned in such a presentation mahalo (thank you) *
serial and beautif
Pity that the music isn't loud enough
Awesome explanation thanks though you slightly missed to mark the center the circle sir :D
@The Program The lead of that giant carpenter pencil has too much dimension to produce any sort of accurate result. A .9 mm mechanical pencil is a better marking tool for making lines closer to the edge of the square’s blade.
very nice......
I want 1 How much Rs.
what is the sharp little pin used for?
The pin is used for marking instead of using a pencil, a pencil line could throw out your cut line buy 1 to 2mm annoying if you are doing fine work.
@@buddahfingersI'm not disputing you how-ever If the mark is off then you have a scratch mark that may not look so good.
@@buddahfingers what's a mm are talking about candy
@@ADEehrh the scratch line is cut off because the measurement is actually to the side of it.
0.34 = it seems to me to only advantage of it. All the others you can easily with a "classic square".
@Bob Craen sorry my ignorance. Can you tell me how I can find the center of a circle using a classic square?
Is it made in the US, China, Germany, Brazil or England ??
👍👍👍👍👍👍
The music. .
Yeah, sorry. It's an old video. I've been meaning to redo it.
@@WoodcraftSupply
Great video non the less! Exactly what I was looking for
Ho cool 😋
You can tell this is 6 years old ... the bloody music. Barely able to watch this, simply awful.
