I have been looking at purchasing an old Pacific Pistol Powder Measure that screws into the top of a normal press thread, and has a slide bar with small bushings in it. Well, these bushings look similar to those used in the shotgun presses, but much smaller and are not available anymore from Hornady. Could someone that has one of these old pistol powder measures give me the dimensions of these bushings so I can see what it would take to make them on my mini-lathe before I purchase one? I just need the outside diameter and height of a typical bushing, hoping that they are at least cut from a standard size rod like 1/2" or 3/4" diameter.
