[QUOTE="Trickymissfit, post: 532108, member: 25383"] the antique beam scales system died almost twenty years ago! Now they are nothing but a paper weight or a door stop. I sent mine to the flea market about twelve years ago, and have never looked back! I fully expect to see them in the Children's Mesuem one of these days! The idea of trusting a dial or digital caliper is OK, but also can be a problem. And trust me Hornaday hasn't got a man in that plant in China checking their output quality! (or RCBS & Lyman) You need something to check them with (forget that idea that they read zero at the zero point, as error tends to stack up during travel). Get yourself a couple dowl pins that are about .500" and maybe 1.000" (almost all are about a half thousandth oversize), and have somebody that works in a machine shope measure them for you. Then use them as a standard to check the calipers from time to time. The calipers you are using are not accurate for measuring small I.D.'s so keep that in mind. The blades have flat surfaces that will lead to error. I measure most of my case neck I.D's with a small hole gauge and a micrometer (a caliper will also work). Down the road buy yourself a good quality micrometer (Starrette, Brown & Sharp, Mitutoyo, or a Fowler), and it will last you a lifetime. gary [/QUOTE]
