These versatile drawing instruments essentially consist of two legs. These are usually made of metal. The legs are connected together at the top by a hinge, allowing them to move flexibly. Compasses also have a crossbar at the upper end where the legs meet with opposite-running threads. Compasses with a spindle guide have a wheel in the centre that can be adjusted with one hand. You can turn this in different directions to spread or close the legs. This allows you to quickly and easily adjust the compass to the desired position.
There is also a needle at the bottom of one leg to secure the compass to a surface. At the end of the other leg, there is a replaceable lead for drawing circles or segments on paper. There are also models with an adapter for attaching a short pencil instead of the integrated lead. If you secure one leg to a surface, you can then determine the radius of a circle by setting the distance of the second leg.
Our STAEDTLER compasses are also available in a plastic case with a hinged lid. Depending on the model, this includes a lead box with four HB leads as well as practical accessories for school and professional use:
If you are looking for a compass set to draw mandalas, you are sure to find the ideal solution in this category. We offer practical mandala sets that contain a quick-setting drawing compass along with the right accessories to create fantastic patterns, including drawing pencils, fineliners and lots more.
The problem with modern compasses is that they have plastic parts which invariably wear out. Worst still, really cheap compasses are available that are so badly made that they are not fit for purpose. So what should you look out for when buying a compass?
I always use Sakura Pigma Micron Pens for drawing mandalas. They come in various sizes and colours but most people start simply using black ink. The size I use most is the Micron 05 (0.45mm nib). For finer lines, I use a Micron 01 (0.25mm nib) and I use the Pigma Brush in the same range, also in black, to fill in larger areas.
I use two rulers. A 30 cm clear ruler and shorter clear ruler too. The longer ruler is useful when drawing the template and the shorter one is easier to use when using it for smaller details. I like this particular ruler as it has a raised edge on one side and a bevelled edge the other. The raised edge means I can draw a straight line with an ink pen and not smudge it.
Here at Graphics Direct we stock a range of Technical Drawing Compass Sets for all budgets. Whether it's a bow compass, 6 piece set or rapid adjustment we stock the following brands Rotring and Staedtler so there is something there for every one
Iris gives you the freedom to draw circles effortlessly. Enjoy drawing single, concentric, or even shaded circles with its unique moving aperture. The walnut centring tool allows you to position your circle to a given point or can be used as a stand to display your Iris.
The 4-in-1 drawing tool: draw in circles and straight lines, construct, copy, and read angles, measure in inches and centimeters, and create geometric patterns and designs. Easy to use, just place a finger on the disc, and using pen or pencil in the locating holes in the cursor, draw a circle. 5-3/4 in. long with a 4-1/2 in. measuring scale.
The humble drafting compass has come a long way from that rudimentary two-armed tool you may have used in your first geometry class. Many available today are fitted with extra joints and interchangeable parts to offer users greater utility and better stability. Whether you are trying to draw perfect circles or achieve precise measurements in your drafting projects, you need a reliable instrument that will stay in place and allow you to work efficiently. Our picks will help you choose the best tool for your needs.
A compass, more accurately known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.
Prior to computerization, compasses and other tools for manual drafting were often packaged as a set[1] with interchangeable parts. By the mid-twentieth century, circle templates supplemented the use of compasses.[citation needed] Today those facilities are more often provided by computer-aided design programs, so the physical tools serve mainly a didactic purpose in teaching geometry, technical drawing, etc.
Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a pen.
There are two types of leg in a pair of compasses: the straight or the steady leg and the adjustable one. Each has a separate purpose; the steady leg serves as the basis or support for the needle point, while the adjustable leg can be altered in order to draw different sizes of circles.
The pencil lead draws the circle on a particular paper or material. Alternatively, an ink nib or attachment with a technical pen may be used. The better quality compass, made of metal, has its piece of pencil lead specially sharpened to a "chisel edge" shape, rather than to a point.
Circles can be made by pushing one leg of the compasses into the paper with the spike, putting the pencil on the paper, and moving the pencil around while keeping the legs at the same angle. Some people who find this action difficult often hold the compasses still and move the paper round instead. The radius of the intended circle can be changed by adjusting the initial angle between the two legs.
Distances can be measured on a map using compasses with two spikes, also called a dividing compass (or just "dividers"). The hinge is set in such a way that the distance between the spikes on the map represents a certain distance in reality, and by measuring how many times the compasses fit between two points on the map the distance between those points can be calculated.
Compasses-and-straightedge constructions are used to illustrate principles of plane geometry. Although a real pair of compasses is used to draft visible illustrations, the ideal compass used in proofs is an abstract creator of perfect circles. The most rigorous definition of this abstract tool is the "collapsing compass"; having drawn a circle from a given point with a given radius, it disappears; it cannot simply be moved to another point and used to draw another circle of equal radius (unlike a real pair of compasses). Euclid showed in his second proposition (Book I of the Elements) that such a collapsing compass could be used to transfer a distance, proving that a collapsing compass could do anything a real compass can do.
A beam compass is an instrument, with a wooden or brass beam and sliding sockets, cursors or trammels, for drawing and dividing circles larger than those made by a regular pair of compasses.[2]
Scribe-compasses[3] is an instrument used by carpenters and other tradesmen. Some compasses can be used to draw circles, bisect angles and, in this case, to trace a line. It is the compass in the most simple form. Both branches are crimped metal. One branch has a pencil sleeve while the other branch is crimped with a fine point protruding from the end. A wing nut on the hinge serves two purposes: first it tightens the pencil and secondly it locks in the desired distance when the wing nut is turned clockwise.
A proportional compass, also known as a military compass or sector, was an instrument used for calculation from the end of the sixteenth century until the nineteenth century. It consists of two rulers of equal length joined by a hinge. Different types of scales are inscribed on the rulers that allow for mathematical calculation. 041b061a72
