![]() Good old fashioned Pink Pearl erasers work well for this, as do Magic Rub white vinyl erasers. Carving your own eraser refills is an option. Rulers work fine for this, but if you have a caliper, it will work even better! If all else fails, and no erasers are the correct diameter for your pencil (yes, it happens!), you may have to consider creative alternatives. If the eraser is gone, take a measurement of the opening where the eraser goes. The easiest way to determine what size eraser you need for your mechanical pencil is to measure the diameter of your old eraser in millimeters. Unfortunately, as with most writing things, erasers were not very standardized over the years, nor are they now! However, there are a few common sizes that fit a good many of the pencils made. Today, many of the early formulas for graphite are still in use by pencil makers. Other early pencil inventors were Corte of France and Hardtmuth of Austria who worked on perfecting the graphite composition. Faber Castell continues to make pencils and other writing instruments today. ![]() Kaspar Faber first commercially produced pencils in 1765 in Stein, Germany by binding graphite with Bavarian clay. In 1662, Friedrich Staedtler opened a pencil shop in Nurnberg, Germany. Scheele in Sweden discovered that plumbago was a form of carbon and named it graphite. A sharpened pencil point can withstand writing pressure of about 3700 pounds of pressure per square inch before breaking off.Įarly references to graphite date back to around 1564 when plumbago was discovered by shepherds and used to mark their flocks. A wood pencil can write on average a line abut 35 miles long - about 45,000 words. Not to mention they are inexpensive and easy to acquire. Wood pencils may very well be the most user friendly writing instrument in the world! Generally non-toxic, wood pencils are leak-proof, can delete your errors and are not subject to electronic snafus. As always with vintage writing instruments, exceptions will crop up! Those that feed from the barrel (below the eraser) are a fairly modern invention! Don't be fooled by leads in the barrel, in older pencils, that was simply a space to store a few extra leads, but that's it - just storage. Most mechanical pencils made before the late 1960s and some even after that are refilled by feeding lead in from the Point End. Refilling your Vintage Mechanical Pencils Here's a listing of lead designations we've compiled: There was no standard for this, so it's always best to try and spec out your lead diameter with an electronic micrometer or caliper. ![]() Many old pencil makers such as Mordan, Baker and others and especially in England and Europe used a letter designation to indicate the diameter of the lead used. Of course, today, there are much thinner diameter leads made, but we're talking antique pencil leads! 1.1mm leads were frequently referred to as "thick" lead and the 0.9mm size was often referred to as "thin" lead. The most common sizes of lead for vintage mechanical pencils were 1.1mm and 0.9mm. 2 pencilī - soft, dark writing, equivalent to no. 3 pencilį - hard, light writing, equivalent to no. H - hard, light writing, equivalent to no. The more B you see in the degree, the softer and darker the lead will write. General rule of thumb to remember is that the more H you see in the degree, the harder and lighter the lead will write. We've noted below wherever were able, the degree of the leads we offer for sale. You can draw anywhere on the screen without getting interrupted.Leads come in a variety of different degrees, also known as hardness which determines how dark or light they write.

Tap to auto-minimize the tool palette and see more options. You can drag the tool palette to a different edge of the screen. When you draw, you can tilt your Apple Pencil to shade a line and press more firmly to darken the line. Choose from several drawing tools and colors, and switch to the eraser if you make a mistake. Double-tap the eraser to view erasing options on your iPad. You can also start by tapping to open the tool palette. Made a mistake? You can erase by object or even by pixel. Use the ruler tool to create straight lines, then rotate them with your fingers. The tool palette has different tools, depending on the app you're using. With iPadOS, move the tool palette around the screen or minimize it so you have more space to draw and sketch.
