Erasers (ink) - Pendemonium!

Which Eraser Do I Need?
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. 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. If the eraser is gone, take a measurement of the opening where the eraser goes. 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. Carving your own eraser refills is an option. Good old fashioned Pink Pearl erasers work well for this, as do Magic Rub white vinyl erasers. If you're handy, you can also make a metal "punch" and punch out refills from a larger block style eraser. A piece of paper makes a good shim, if a ready made eraser almost fits, sometimes all it takes is a small piece of paper wrapped around the base of the eraser to make it fit just right. On the opposite end of this theory, sometimes taking a ready made eraser that is just a tad bit too big and shaving off a little bit will provide you with the correct fit. You just need to think outside the box a little bit when it comes to refilling erasers on your vintage mechanical pencils. Click here for a list of Mechanical Pencils and Eraser Sizes
6mm diameter Erasers are Back!!! Small things make a difference!
Many vintage pencils including Parker 51, Parker Vacumatic, Sheaffer Snorkels & other Sheaffer models plus a wide range of other older mechanical pencils use 6mm diameter erasers. Slowly, but surely, most of the companies stopped offering this popular size eraser, until finally, within the last year, the last company still offering the erasers, Sheaffer, dropped them from their line up, too. So many of these pencils are still in circulation and in use, what to do if you make a mistake? The only option was hand carving an eraser one at a time yourself. That is quite a chore, we've done that many times for odd sized erasers. Instead of hand carving erasers, we decided to talk with a friend who is a tool and die guru - extraordinaire and see if he could come up with some kind of machine where we could somewhat easily make 6mm diameter erasers. Lo and behold, a few weeks later, an amazing machine arrived on our doorstep and we once again have 6mm erasers made from pink pearl eraser blocks - so you know they erase very nicely. We were thrilled and to be honest, even if it isn't the most exciting thing in the world to do, it's pretty darned satisfying being able to turn out perfect 6mm diameter erasers!
