There are many tutorials on making a square to check that corners woodworking square size function 90 degrees, but they all require you to use a square to check. So how can you make a square, without using a woodworking square size function How were they originally made if the accuracy needed to be right, but modern methods of measurement and manufacture were not available?

I'm just starting out with woodworking, and as I don't have a project I want to complete as yet, I'm interested in making many of the tools I'd use as part of the learning process mallets, squares, marker squqre etc.

Budget is very tight, but I don't mind incremental steps to the end goal, such as making a just-about-good-enough bench on which to build a better functiob.

I've been watching a lot of Paul Sellers Youtube videos and they have spurred me on. How were they funcrion made if the accuracy needed to be right, but modern methods of measurement and manufacture were not available.

A long time woodworking square size function, the Great Pyramid of Giza woodworking square size function built. This was way before any modern, recognised system of working out a square - and yet it is square. I guess you have a piece of woodworking square size function to hand? If you feel that is cheating, you woodwirking use a ruler woodworking square size function draw that ssuare, woodworking square size function make it yourself with string.

Well, to start, today's squares really are pretty cheap and it wouldn't cost much more than the materials if you are going to make it out of metal.

However, making one out of wood, if you have a rectangle with the opposite sides the same length, then measuring the distance between opposite corners funnction the way to go. When both measurements are equal, all corners are 90 degrees.

If accurate measurement is available you can rely on the rulealready referenced in the Answers you've received. Assembling the parts dry I marked 6cm across on the short arm the stock and 8cm up the blade.

Then I applied glue and inserted the blade into the stock and lightly clamped, adjusted the position until I measured 10cm precisely between the two marks and left it until the glue had set. After the glue was hard I drilled through the joint for three pins to lock the joint securely. I used copper here wooeworking other metals can be used as well even mild steel, e.

There isn't fujction significant difference in strength or stability for a piece like this going with wood over metal, I used the copper purely for looks. Woodworking square size function second method can fnction be used where you have a qsuare enough working window on the adhesive used, or you don't glue and are merely holding the blade in the stock e.

What you do is directly compare the squared line drawn by the try square against itself. I'm just starting out with woodworking, and as I don't have a project I want to complete as yet, I'm interested in making many of the tools I'd use as part of the learning process mallets, squares, marker gauge etc.

This is an excellent idea and you'll learn a great deal doing this, in addition to creating a host of useful tools, jigs and accessories in the process of course. Please be sure to ask further questions if you'd like input on other things you might like to build. Here's an existing Question about a that you might find informative: What's a bench hook? If you can draw straight lines, you can make a perfect right angle using a compass - see this simple diagram:.

Draw straight line 1then owodworking of a circle 2 and 3 - as long as they are centered on the same line and overlap, their woodworkiny distance doesn't matter. Join the two points A and B siize they intersect with straight line 4.

You now have two lines at a woodworking square size function right angle Drawing an accurate circle is as simple as putting a pin at the center, a string with a loop at each end with one loop around the pin and the other around the tip of a pencil. The larger the scale on which you do this, the smaller the error will be. This is how I am learning woodworking, and eventually metalworking, as well. It's a good way to go.

Building squares is a nice little project. Squafe is possible to make an woodworking square size function square without having an accurate square to check woodworking square size function, but you need things that are straight. Suppose you can obtain two pieces of wood that have at least one flat, straight side. Those will be the outer sides of your square.

Use one of the pieces to draw a straight horizontal line on something flat. Temporarily join the two pieces together such that wquare can still be rotated with respect to each squar -- like, put a single screw through them, or a single dowel, or whatever.

Get them as square as you can. Then put one side along the line you just drew with Woodworking Ruler Square Layout Update the square arranged like the letter L, and use your new square to draw woodworking square size function perpendicular line.

Now flip the whole thing overso that it is now a backwards L, and try to draw the exact same perpendicular line. If the square is accurate, the perpendiculars will coincide. If it is not, you can estimate how far out sizd square your square is, adjust it, and try again. Keep doing that until you get something that is as close to functoon as you want it to be, and put another fastener into the square so that it woodworking square size function no longer rotate, woodqorking hey, you have an accurate square built out of only an accurate straight line.

Now of course the question is woodworking square size function do I produce an accurate straight line? You do not say how far back in squars you want to go.

The ways that the ancient Egyptians made sure their building blocks were square are rather woodworking square size function than the ways that medieval carpenters used to make square buildings, and those are rather different than the techniques used to build square, accurate machine tools fnuction the industrial revolution. Make your question more precise if you are interested in the history of tool building. If you want to see how it was done years ago without fancy modern tools you should really start woodworking square size function "The Woodwrights Shop" with Roy Underhill it's on PBS and has a lot of content available for streaming.

In funvtion simplest form pace it on the edge of a table and draw a pencil line. Flip the square over to see how far off it was, use a plane or chisel to remove just enough wood to get it closer. Then Flip it around and draw another pencil line, etc.

Until it is as accurate wwoodworking you want. This will give you one 90 degree corner. From there just measure two sides that are the same length and functuon. But I'd suggest woodworking square size function a try-square or other such tool. They are accurate, not too expensive and very useful. I like Roy Underhill. I haven't watched that episode, but if you want to check a homemade square for squareness, it seems like the squarre way would be to take four pieces of material that are the same, for instance 4 6" sections of free paint stirrers from your local big box store, lay them over lapping in a square, put a nail through each corner and shift the frame till the diagonals measure the same.

You square things up in a similar manner in carpentry. If you want to woodworking square size function if something woodworking square size function functioj, you measure the diagonals and adjust funcgion they're the same. When they are, it's square. No math involved. I think the answer you're looking for is simply woodwworking.

When this happens. A straight stick inserted perpendicular into the level ground will NOT create a shadow. Woodworkig the shadow is located exactly in the hole in which the stick is inserted. If woodworking square size function is done with a stick and a shallow pool of water, the result is a perfect right angle with relation to the surface of the water and the edge of the stick.

How can they create a triangle like this? Tie 12 knots in a piece of rope, equally spaced: And then make it into a triangle: And that gives a right angle.

Although theoretically correct, the rope with equally spaced knots is extremely impractical for woodworking - first there is the issue of tying equally spaced woodworking square size function -good luck; then there is the Woodworking Measuring Square Number issue of woodworking square size function woodwoking rope or string constantly taut since any tension on the rope is going to produce a measurable change in length - still it's kind of fun to fantasize about.
